Comparing Bowden Extruders and Direct Drive Extruders

The extruders of a 3D printer can be divided into two types according to their different feeding methods: Bowden Extruder and Direct Drive Extruder. The following will compare and contrast the two types of extruders.

Bowden Extruders

3D printers with Bowden Extruders have the extruder and stepper motor installed on the printer outer shell. The filament is fed remotely through the Teflon tube to the nozzle.

Two common 3D printer brands that feature the Bowden Extruder are Ultimaker and Delta 3D printer.

 

 

 

Bowden Extruder

Bowden Extruder

Advantages of a Bowden Extruder

  1. The extruder is lightweight, with small inertia giving it precise movement and positioning
  2. The moving speed of the extruder can reach 200~300mm/s, resulting in fast printing speed
  3. The nozzle and extruder can be separated for easy maintenance

Disadvantages of a Bowden Extruder

  1. The feeding distance is relatively long, the resistance is high, meaning the stepping motor of extrusion is required to have a higher torque.
  2. The extruder and the nozzle need to be connected with a Teflon tube and a pneumatic connector. This design is more likely have a failure than the Direct Extruder.
  3. Both the filament and the Teflon tube are elastic. Additionally the pneumatic connectors has a certain amount of movement space. Therefore, the required retraction distance and speed are greater, which is not as accurate as the Direct Extruder.
  4. The distance between the extruder and the nozzle is long, so the filament in the feeding tube is more difficult to use up.
  5. It is not very convenient to change the filament, especially when replacing the old filament with new filament without pausing the printing process. The printing process must be paused because the head of the filament cannot be withdrawn when it is in the feeding tube.
  6. Because the feeding distance is too far, once elastic filament is used, the filament cannot be fed normally. Therefore 3D printers with Bowden Extruders generally cannot print elastic filaments.

Direct Drive Extruders

 

3D printers with Direct Drive Extruders usually have the extruder and stepper motor installed on the nozzle and the filament is fed directly to the nozzle.

Examples of 3D printers with Direct Extruders are Raise3D’s E2, Raise3D’s Pro2 Series, Raise3D’s Pro3 Series, and Raise3D’s E2CF.

Direct Extruder

Direct Extruder

Advantages of a Direct Drive Extruder

  1. The Direct Extruder has more precise control of the loading amount than the Bowden Extruder, and the retraction is more precise. This results in a better surface on the printed model.
  2. The torque requirement of the extrusion stepper motor is relatively low.
  3. It is easier to change the filament.
  4. It has a better printing performance for elastic filaments.

Disadvantages of a Direct Drive Extruder

  1. The hotend of the nozzle, the extruder, the stepper motor, the cooling fan are integrated, making it inconvenient to disassemble and maintain
  2. The extruder is heavier, especially for dual-nozzle printers, which have large inertia when moving. It is relatively difficult to accelerate and decelerate, so the printing speed is generally lower than that of the Bowden Extruder

What Are Dual Extruder 3D Printers and IDEX 3D Printers?

Dual extruder 3D printers perform advanced functions to accommodate a wide variety of 3D printing projects, making a 3D printer an important asset. Dual extruder 3D printers have many applications and can be incorporated into business operations to improve prototyping, production, and manufacturing processes. A comprehensive understanding of a dual extruder 3D printer’s mechanical setup and functionality is crucial for businesses to decide whether they need a dual extruder 3D printer, and if so, what type of dual extruder 3D printer will be the right one for their needs.

What is an Extruder? What is the Function of the Extruder in a 3D Printer?

FFF 3D printing is the process of melting and extruding a 3D printing material, also known as filament, then building up thin layers of the melted material to create a physical object. The system of parts that operate together to melt then release the melted filament to build up the layers of a 3D printed part is generally known as the extruder or extruder system of an FFF 3D printer. The two main parts of an extruder system are the cold end and the hot end.

The 3D printer feeds the spool of 3D printing filament to the cold end. The cold end generally consists of a motor and gear. The motor runs to turn the gear. The gear then grabs and guides the filament strand through a tube that connects to the hot end.

The hot end receives the filament that is passing through the tube from the cold end. It passes the filament into a chamber that is already heated to the melting temperature of the filament. This heated chamber is also known as a heat block. The melted filament is then ejected through nozzles onto the build plate.

What is a Dual Extruder 3D Printer?

Why Are Dual Extruders Important?

In short, the benefit of having a dual extruder 3D printer is performing dual extrusion 3D printing. Dual extrusion printing means both extruders will be used during the printing process. This capability enables a dual extruder 3D printer to perform more advanced functions and processes to accommodate a wider variety of 3D printing projects than a 3D printer with a single extruder.

 

Two typical uses of a dual extruder 3D printer are printing are for:

  1. dual-color model
  2. dual-material model

Dual Color Model

A dual-color model is when one model has a 2 different color pattern. The two different colors can show an image or information. An example of a dual-color model is the Raise3D coin, which is printed in the colors red and black. The red and black colors function not only to create the Raise3D logo but also to distinguish the company’s contact information.

Dual Material Model

A dual-material model is when one model uses two different materials, also known as filaments*.

*Not all materials can print with another material. To learn more about which materials can be printed together, please contact Raise3D.

A good example of why being able to print dual-material models is important is in printing a model that needs a support structure. Support structures are usually required for parts that have an overhang or bridge geometry. A support structure will prevent the overhang or bridge geometry from breaking before the filament has a chance to cool off and solidify. Support structures are created in the 3D slicing software with the model and assigned to an extruder and 3D printing material to print this support structure.

Dual Material 3D Printed Parts

A support structure can also be printed with a second extruder and material. This means one extruder and material will be assigned to print the model, while the other extruder and material will be assigned to print the support. This method of printing a support structure is another example of printing a dual-material model.

 

Side Note: A support structure can also be printed using the same extruder and material as the model part. This means the same material and extruder will print the model and the support structure.

PLA Printed Part After Dissolved PVA Structure

It is important to remember that not all 3D printing materials can be paired together. Therefore, the material of the support structure will depend on what can work with the material that is used for the model.

Two common combinations of materials used for printing a model with a support structure are:

  1. PLA filament for the model with PVA as a support material
  2. ABS filament for the model with HIPS as a support material

However, removing the support without causing damage to the model is an important concern to keep in mind. PVA filament is a popular and practical material for support structures when applicable.

Dual Material 3D Printed Part

Dual Material PLA and PVA 3D Printed Part

PVA is water-soluble, meaning it dissolves in water. Therefore, when a model with a PVA support structure is submerged in a water bath, the support will eventually dissolve, leaving behind the model. In general, using soluble supports will make the process of removing the support less painful and less of a hassle. However, soluble supports are invaluable for models whose design makes it difficult or impossible to remove the support structure if the support’s material is not dissolvable. Below is an example of a model that would be difficult to remove the support structure if the material for the structure was not soluble.

PLA 3D Printed Part

Close Ups of 3D Printed Parts

Another common example where dual-material printing is necessary is in producing 3D printed parts with texture. Dual extrusion can achieve this result by printing with two materials: for example, one hard material and one flexible material. The hard material extrudes from one extruder while the flexible material extrudes from the other extruder. As a result, the printed part will be partially soft and flexible, and partially rigid.

 

There are times when a part can be dual material, with each material being a different color, making it dual color as well. An example of a dual material and dual color model is this Rigid Heel Insole. It is printed in the materials TPU and PLA, in the colors red and white.

A dual extruder 3D printer’s capability to print models in two colors or two materials gives its users more freedom when designing the models and more applications.

What are the Types of Dual Extruder 3D Printers?

A dual extruder 3D printer will feature one of two types of dual extruders, dependent or independent extruders, also known as IDEX. For this guide, we will refer to non-IDEX extruders as dual extruders and non-IDEX 3D printers as dual extruder 3D printers.

 

People mainly categorize the dual extruder 3D printer by how the dual extruders are set up.

 

  1. One type is when both extruders are attached and moving together when printing, which is called dependent dual extruders. However, dependent dual extruders are also known as dual extruders.

 

  1. The other type is when both extruders are detached and able to move individually along the axis when printing. This type of extruders is known as independent extruders or IDEX.

 

For this guide, we will refer to non-IDEX extruders as dual extruders.

Dual Extruders

Since dual extruders are attached and move together during printing (also known as contact design), there is a risk of the nozzle interfering with the print job during the printing process. To minimize this risk, the dual extruders must have electronic lifting technology. A lifting nozzle technology leads to a higher quality print job because it will lift a nozzle up to minimize the risk of the nozzle interfering with the print job. The Pro2 and Pro2 Plus from Raise3D are examples of dependent dual extruder 3D printers with a 1.5 mm lifting nozzle technology.

Pro2 Dual Extruder 3D Printer

Pro2 Dual Extruder 3D Printer

Independent dual extruders are detached and can move individually along the axis when printing, giving a dual extruder 3D printer with IDEX added capabilities.

 

It is important to note that while both types of extruders produce high-quality print jobs and can perform advanced processes, a dual extruder 3D printer with IDEX can perform even more specialized functions.

What is an IDEX 3D Printer?

An IDEX 3D printer is a 3D printer with independent dual extruders. An IDEX 3D printer, such as the E2 from Raise3D, is capable of even more specialized functions such as printing in Duplication Mode and Mirror Mode.

E2 Desktop 3D Printer

E2 Desktop 3D Printer

Duplication Mode is printing in a synced pattern. Duplication Mode one extruder creates a part, and the second extruder creates an exact copy of that same part. This advanced feature will double production within the same timeframe.

 

Mirror Mode is when the independent extruders work individually to print a part and an inverse of that part. This means one extruder prints a part while the second extruder simultaneously prints the inverse of that part. This advanced feature will create two 3D printed parts at the same time, increasing production, while shortening a project’s timeline.

 

When printing in Duplicate or Mirror mode with IDEX, both extruders will move independently along the axis in a synced (duplicate mode) or mirrored (mirror mode) pattern. This also means that even with an IDEX 3D printer, it is not possible to print 2 different models from 2 different extruders at the same time (unless the two models are mirrored).

If the IDEX 3D printer is not printing in Mirror or Duplicate Mode, one of the extruders can remain off to the very of the other side while the other extruder prints. This means an IDEX printer can perform print with one extruder without the risk of damaging the print job with the motionless extruder.

If a dual extruder 3D printer is well designed and manufactured and has the proper software settings it can produce high-quality dual extrusion prints, regardless of whether or not the printer has IDEX. However, IDEX opens up the printer’s functionality beyond producing high-quality dual extrusion prints, to printing in Duplicate mode or Mirror mode increasing the productivity per machine per print round.

Different dual extruder 3D printers can perform dual extrusion printing and more advanced functionalities. This opens up their capabilities making these 3D printers important assets capable of improving operations such as production and manufacturing in a wide range of industries.

How to 3D Print PVA Supports with a Perfect Surface

PVA filament is a 3D printing material mainly used for support structures for models printed in other filament. Common PVA can only be printed well with PLA. Higher grade product like PVA+ from Raise3D is compatible with many more popular materials such as PETG, PA (nylon) and PA12 CF. PVA is water-soluble, meaning it dissolves in water. This characteristic makes it a popular 3D printing material for support structures because it can be easily removed, especially for models whose designs make it difficult or impossible to remove the support structure by hand.

However, when printing with PVA filament, it is important to remember that it’s a material that absorbs moisture easily. If it is not processed properly, there is a chance the printing will fail.

PVA is not the only type of 3D printing material that can be removed by dissolving. Other filaments that can be dissolved include BVOH and HiPS from BASF, but these 3D printing materials usually suffer from a lower printing success rate. Also, these materials have a printing time that is 2-3 times longer than usual. Therefore, users need to do what they can to lower the risk of printing failure.

In this guide, we will introduce the basic settings in ideaMaker for specialized support filaments such as PVA, BVOH, and HiPS. These specialized support filaments can be effective for 3D printers from Raise3D as well as printers from other brands*.

*Disclaimer: When reading through this guide, keep in mind that while Polysupport is another kind of specialized support filament, it is not dissolvable. Therefore, the slicing settings in this guide do not apply to it.

Support Settings

Support settings for PVA are different from conventional filaments, because PVA supports dissolve and can be removed.

When applying PVA supports, the most commonly used settings are marked by red boxes shown in the above picture.

Infill Pattern

(Left: Lines, Right: Grid)

You can choose the pattern of the support structure. These patterns have a default setting of Lines. However, while it is easy to break them by hand, supports using this pattern are also less stable and it is easier for them to deform and collapse.

Since PVA filament can be dissolved, there is no requirement for manually removing the resulting supports. Therefore, an advantage of PVA is that users have the option to choose more stable patterns, such as the Grid and Triangles, which otherwise would be less desirable options for supports that need to be removed by hand.

Horizontal Offset

(Left: 0.2mm, Right: 1.0 mm)

Users can set the distance of the gap between the support and the object. By reducing the distance, the support structure will stick more tightly to the overhang surface. This helps to prevent collapse and raise the smoothness of the downward-facing surface.

(Left: 0.2mm, Right: 1.0mm)

Vertical Distance Between Object to Top\Bottom Surface of Support

(Left: 0 layer, Right: 1 layer)

The vertical distance between the object and the support top/bottom surface can be changed, and users can set the distance in layers. With 0 layers, the object and the support will stick together. This helps reduce the risk of prints failing, such as the overhang area collapsing.

When applying the same printing material for both object and the support, such as PLA filament, a distance setting of 0 layers will result in the support not easily breaking away from the object. But if the support is printed with PVA, the PVA support can be dissolved rather than broken away, which is far more useful and convenient.

The gap distance is calculated by the number of layers and the layer height. (If layer height is 2.0 mm, gap of 1 layer is 2.0 mm).

Dense Support

Dense support is created by increasing the density of a few interface layers between the object and the support structure. It can prevent extruded mesh from falling into intervals of the support structure.

Although such settings will increase the printing time and cost, these settings are still recommended if you want to increase printing stability and surface quality.

To change the setting, you can click on “Dense Support” tag next to “Support” tag.

Number of Dense Support Layers

The green part is normal support, and the blue part indicated by the red arrow is dense support.

You can change the number of dense support layers between the regular support structure and the object.

Generally, three layers are enough, but if you want to entirely remove support, it is suggested to increase the number of layers.

Dense Support in Bottom

Users can add dense support as initial layers in the bottom of the support structure.

Although dense support results in more printing time, it helps reduce the chance of printing failure by increasing the stability of PVA support.

Dense Support Infill Ratio

(Left: 80%, Right:100%)

You can set the density of the dense support area. This works the same as the infill density of the model itself. As density increases, the support structure grid will gradually become tighter while the interface between the model and support improves. Reducing the density can shorten printing time but it is suggested to keep density at least at 80%.

How to Apply Texture in ideaMaker

With ideaMaker Texture, the user can skip lengthy CAD processing and generate a 3D texture directly from a 2D greyscale image, and can apply it to the model’s surface. Examples of 2D images that can be spread over a model’s surface include patterns, figures, or logos. ideaMaker uses slicing to automatically convert any image into a 3D texture to be printed as a unique surface finish. ideaMaker Texture expands the possibilities of a model’s appearance while broadening the appeal of it.

What can Texture be applied for?

Texture can easily turn any 2D image into 3D texture on a model’s surface. This enables the user to try out an unlimited amount of images for a huge range of appearances. This is useful for any scenario that requires customization, with customized digital product appearances benefitting especially. Examples of customized digital product appearances include headphones, controllers, automotive interior parts, artistic crafts, household products, miniature architecture, and computer mice.

Benefit of Texture

ideaMaker Texture is user-friendly and saves a significant amount of time when compared to conventional modeling requirements and procedures. Textures can be modified by applying a 2D image and changing a few settings. This easy-to-use feature gives those still learning modeling skills the possibility of customizing the surface of a 3D printable object with a texture. There is a Texture module in ideaMaker Library which provides a vast number of 2D texture images, and where the user can import a texture image from an online library to ideaMaker with one click, as well as also having the option of uploading a local image they designed to ideaMaker Library, and share the texture, the model appearance design, and customization experience.

Texture is easy to use and only takes a few steps to generate the 3D texture on a model. All that is necessary is to import an .STL into ideaMaker 4.1.0, then click the Texture icon in the toolbar and choose an image. Then adjust the texture mapping by degree, position, and number of duplicates until achieving the desired parameters. After that, the user can slice and preview the resulting application of the 3D texture on the surface of the model.

 

How to use Texture

The process of applying Texture is designed so that beginners and non-professional designers can fully utilize this feature, only needing 4 steps.

Step 1Import Model

  1. Open ideaMaker 4.1.0 and import your model for slicing. If your ideaMaker version is lower than 4.1.0, please visit Raise3D Download Center and download the latest ideaMaker.
Import model

Step 2: Add and Adjust Texture for Model

  1. Select the model and click the Texture icon in the tool bar. Select “Custom Texture” from the pop-up menu to select customized texture image.

Add and Adjust Texture for Model

 

  1. Click “+” in the “Custom Texture” menu, then upload a texture image. ideaMaker will automatically generate a 3D texture according to the information in the image. ideaMaker provides the user certain parameters to adjust the wrapping of the image. Basic and advanced settings will be discussed in later chapters.

How to Apply ideaMaker Texture

 

There is no image requirement for size, format, color or resolution (supported format includes .jpg, .jpeg, .bmp, .png, .texture). ideaMaker will convert information in the image to greyscale values. The greater the contrast in the picture, the more notable the 3D texture will be on the model.

Based on image content, the user can apply Texture to a variety of situations including pattern (left), figure (middle), text and logos (right).

Steps to Apply ideaMaker Texture

 

In ideaMaker 4.1.0, Texture cannot be applied on a flat surface of the model that is parallel to the print bed. Therefore, when adding a textured image, the user should consider the model’s orientation and the mapping of an image on the model’s surface.

Basic Tuning for Texture

ideaMaker 4.1.0 provides several useful settings to easily customize the application of a texture.

1. How to shift texture on the model?

Changing values in “Move” will shift the texture on the model. Please note, texture in ideaMaker 4.1.0 is wrapped according to axial symmetry. A value in the first box will decide the horizontal offset between the texture and the axis.

Positive value: Textures will move closer to the axis; Negative value: Textures will move away from the axis

Positive value: Textures will move closer to the axis; Negative value: Textures will move away from the axis

 

A value in the second box will decide the offset in the vertical direction.

Positive value: Texture moves downwards; Negative value: Texture moves upwards

Positive value: Texture moves downwards; Negative value: Texture moves upwards

 

2. How to Adjust the Repetition of Texture

Adjusting the value of “Repeat” changes how the texture repeats. A value in the first box adjusts the way the pattern repeats in horizontal directions while a value in the second box decides repetitions in vertical directions.

3. How to Rotate the Texture?

With “Rotation”, the texture will rotate clockwise or counter-clockwise along the axis.

Positive value: Counter-clockwise rotation

Positive value: Counter-clockwise rotation

 

Negative Value: Clockwise rotation

Negative Value: Clockwise rotation

 

Advanced Settings of Texture

Besides adjusting the arrangement of texture on the surface, a user can also change settings in the “Texture” category of slicing templates. Some useful options include Texture Resolution, Texture XY Offset and Texture Outside Only.

Advanced Settings of Texture

 

Texture Resolution decides how accurate the image will be when converted into 3D texture. The higher the value is, the sharper the 3D pattern will be.

Left: Resolution=0.1mm; Right: Resolution=0.5mm

Left: Resolution=0.1mm; Right: Resolution=0.5mm

 

Texture XY Offset decides how much of the model surface will be extruded or pulled based on the texture image within a certain grey value. The larger the number is, the more pronounced the extrusion or pull will be. A negative value inverts the direction of the extrusion or pull.

Left: Offset=1.00mm; Middle: Offset=0.5mm; Right: Offset=-1.00mm

Left: Offset=1.00mm; Middle: Offset=0.5mm; Right: Offset=-1.00mm

 

A user can enable Texture Outside Only to allow ideaMaker to identify inside the surface of the model and add texture to only to the outside. For typical geometry, like a vase, ideaMaker can identify its inside and keep in its original, non-textured state.

Left: Texture Outside Only=Disabled; Right: Texture Outside Only=Enabled

Left: Texture Outside Only=Disabled; Right: Texture Outside Only=Enabled

 

In addition, the user can add modifiers to block certain areas from generating texture.

Texture is not applied in an area blocked by a modifier

What Are the Quality, Standard and Speed Templates?

ideaMaker has built-in three slice templates with set parameters, namely Speed, Standard and High Quality. You can choose the appropriate slice template according to your needs.

1. How to Find the Slice Template?

  1. Open ideaMaker, click “Slice” in the menu bar, and then click “Manage Templates”.

    Open “Manage Templates"

    Figure 1 Open “Manage Templates”

  2. In the “Select Template” interface, select your printer type and filament type. When you select the filament in the menu bar, each filament followed by “template” in brackets on the right side is the built-in slice template of ideaMaker.

    Select ideaMaker built-in filament template

    Figure 2 Select ideaMaker built-in filament template

  3. Take the printer Raise3D E2, filament “[Raise 3D] PLA 1.75mm (3 templates)” as an example, ideaMaker provides you with three template types, namely Speed, Standard and High Quality.

    Three kinds of templates

    Figure 3 Three kinds of templates

2. The Basic Differences Between the Three Slice Templates

  1. Speed: The “Speed” slice template is designed to increase the printing speed of the model, and you can obtain the printing results in the shortest time, thereby greatly improving the productivity. But the pursuit of fast printing will sacrifice some printing accuracy, because the “Speed” template has a higher layer height and a faster printing speed, so the printing effect and dimensional accuracy are the lowest.
    Speed slice template is suitable for:

    • Printing models with fast product iteration speed; printing models for updating the product.
    • Small batch production, fast production to maintain the highest productivity.
    • Printing the initial model to verify the design concept.

      Speed slice template

      Figure 4 Speed slice template

  2. The printing speed and printing quality of the “Standard” slice template is medium. The printing quality is higher than that of the speed template, and you can print models with medium precision requirements, such as auto parts, spare parts and tools.

    Standard slice template

    Figure 5 Standard slice template

  3. The “High Quality” slice template aims to pursue the highest precision and the highest printing effects. Because the printing speed is low, the productivity is relatively low. The “High Quality” slice template is suitable for printing:
    • Models with high precision, rich details and high surface quality
    • Appearance verified products
    • Converting the design drawings into entities to show the details of the design

      High Quality slice template

      Figure 6 High Quality slice template

  4. Take “[Raise 3D] PLA 1.75mm (3 templates)” as an example. The table below shows the differences in the basic parameters of the three slice templates Speed, Standard and High Quality. For more parameter differences, please refer to Appendix 1.

What is An Industrial 3D Printer?

Businesses need industrial 3D printers for their quality 3D printing results. However, the necessary high level of 3D printing quality ultimately requires a more expensive 3D printer. Therefore, industrial 3D printers have a higher price tag. Depending on the kind of specialized functionalities needed in the 3D printer, budgets for an industrial 3D printer is at least $5,000 – $10,000. However, depending on other characteristics such as print size and materials, it is not uncommon for an industrial 3D printer price to be over $1 million. For this article, we will focus on industrial 3D printers priced on a $5,000 – $10,000 budget since they are within reach of businesses of all sizes.

Industrial 3D Printer Features

An industrial 3D printer is designed to be a high-quality machine with mechanical as well as hardware and software features in place to ensure a high success rate and high print quality.

Some mechanical features that contribute to an industrial 3D printer being a high-quality machine include:

  1. A full metal frame for smooth movement during the 3D printing process
  2. A metal build plate for even heat distribution
  3. The design of an extruder system repeatedly tested and still be able to perform over the long run to show its reliability

Some fail-safe measures that help ensure a high success rate include:

  1. A design to be able to resume the status of print job in the case of a power outage
  2. Filament runout sensors that pause the print job when the lack of filament triggers the sensor

A feature that contributes to a high print quality includes a 32-bit ARM Cortex motion controller board for high position accuracy and smooth movement for the motion system during the printing process. A motion controller receives the instructions for creating a 3D printed part and segments the instructions into manageable steps. Each step will include a set of actions performed by the 3D printer. An industrial 3D printer will have a high performing controller, such the 32-bit motion controller on Raise3D printers to segment the instructions into smaller steps. By having smaller steps the 3D printer will be performing less action within each step. This allows industrial 3D printers to have more accuracy and smoother movement while being regulated by the 32-bit motion controller.

The high-quality design of an industrial 3D printer is important because the quality of the build of the machine will affect the 3D printing process, which will affect the quality of the final product.  For example, every 3D printer has a flat, heated surface, called a build plate where the printer layers the 3D printing material to create a 3D printed part. A high quality and well-designed build plate and printer bed will ensure a successful print.

It is important to understand that since the build plate is where parts are created, the design and structure of the build plate can affect the 3D printing process, and ultimately the final result of the 3D printed part. Therefore, an industrial 3D printer’s build plate will be designed to a higher standard.

For example, all Raise3D printers are designed with a metal build plate. The metal build plate is very flat and provides even heat distribution. The flatness and even heat distribution make the print model stick to the print bed well, with less of a chance of warping off the print bed. The even heat distribution ensures that all 3D printing materials, filaments, are not damaged during the printing process due to unequal heat distribution across the build plate.

For the industrial 3D printer’s design and features to be performed to a high standard, the printer needs to be built in a high-standard factory. For example, the Raise3d factory is ISO certified under ISO 9001 and ISO 14001.

Industrial 3D Printers Have Dual Extruders

Most industrial 3D printers feature dual extruders because dual extruders expand the printer’s printing capabilities. First, it is important to understand that depending on there are two types of dual extruders available.  Industrial 3D printers can feature dual extruders which work in unison or independently of one another. Extruders that work independently of one another are known as Independent Dual Extruder System, IDEX. Depending on which kind of dual extruders are featured on the industrial 3D printer, leads to even more specialized functions.

In general, dual extruders enable the printer to process a wider range of 3D printing materials, also known as filaments. The ability to process a wider range of filaments allows the industrial printer to create more kinds of 3D printed parts. This includes 3D printed parts made up of two colors, parts made of two different filaments, and parts that require a support structure during printing.

Support structures are only created using a filament that can act as a print support material. Two examples of support material include HIPS which is commonly paired with ABS, and PVA which is commonly paired with PLA. PVA is a specialized filament that is a water-soluble 3D printing material. It is often used in support structures and for water-soluble 3D printed parts. However, PVA can only be processed if the 3D printer has dual-extruders. Industrial 3D printers, like those from Raise3D, are designed with dual extruders and can accommodate filaments with processing requirements, like PVA.

Simply because the industrial 3D printer has dual extruders does not mean that both extruders must be used for each print job. There are times when print jobs only require one nozzle to produce the 3D printed part.  However, a 3D printer operating with one extruder runs the risk of accidentally hitting the part with the extruder/nozzle that is not in use, causing issues or print failures. Industrial 3D printer manufacturers implement two common methods to prevent this problem.

The first method is to lift the non-printing nozzle higher to the model layer that is being printed. Nozzles stick out of extruders and can hit the part being printed when they are not in use. Under the design of the first method, an industrial 3D printer will enable nozzles not in use to lift into the extruder to not hit the printed part. For example, Raise3D’s Pro2 dual extruder 3D printer and the Pro2 Plus large format 3D printer lift nozzles to produce high-quality dual extruder prints. Both of these Raise3D printers have a 1.5 mm nozzle lifting distance, meaning the nozzles will lift 1.5 mm away from the printed part.

The second method requires an industrial 3D printer featuring an independent dual extruder system, IDEX. The IDEX printer will prevent print issues from the unused extruder by moving the unneeded extruder/nozzle away from the part being printed. For example, the E2 desktop 3D printer from Raise3D is an industrial 3D printer with IDEX. If the E2 was printing with only one extruder, the E2 will use its IDEX capability to separate the two extruders. Then it would push the unneeded extruder off to the side, away from the print job. By separating the two extruders, the E2 can continue printing without running the risk of damaging the print with the unneeded extruder.

Both methods are proficient at printing 3D printed parts designed for an industrial 3D printer with dual extruders. Regardless of the kind of dual extruders an industrial 3D printer features, it will produce a high-quality 3D printed part. However, depending on the production and manufacturing needs of a business, IDEX can offer additional features such as the E2’s Duplicate or Mirror Mode. Duplicate mode is when the E2 prints a part and a copy of the part at the same time. Mirror mode is when the E2 prints the part and the part’s inverse at the same time. Both Mirror Mode and Duplicate Mode use IDEX to print one part on each extruder. Both processes lead to faster and more efficient production. If faster production and manufacturing is important, IDEX may be a function to keep in mind when searching for an industrial 3D printer.

How the High-Quality Design of an Industrial 3D Printers Improves Printing Accuracy

The high design standard of industrial 3D printers leads to better accuracy during the actual 3D printing process. A high degree of accuracy is crucial in the printing process because it helps produce a better final product.

3D printing is a process where thin layers of material are built up to create a part. To build these layers, the 3D printer needs to be able to smoothly glide back and forth without malfunctioning or losing its position. Therefore the machine itself needs to be built to protect against these types of issues during the printing process. Industrial 3D printers are designed to a higher standard to have a smoother printing process and produce a high-quality 3D printed part.

For example, Raise3D industrial 3D printers are all built with a full metal frame which acts as a reliable motion system for smooth movement and precise positioning during the 3D printing process. The full metal frame on Raise3D’s printers is made of aluminum. Aluminum is both lightweight and durable to withstand the force of the 3D printer’s back and forth movement during the printing process. If a printer’s frame is not metal, it may not be strong enough to withstand the force from the printing process. If the frame can not handle this type of force, it can be damaged by the back and forth movement during the printing process. If the frame is damaged then the X, Y, and Z axes will be altered. The X, Y, and Z axes are used to measure the part’s design and size. If the X, Y, and Z axes are altered, they can not follow the design and size instructions for the part. Axes that can not match the instructions for a part’s design will lead to an inaccurate final 3D printed part. However, a full metal frame like that found on Raise3D printers is strong enough to withstand this type of force to lead to an accurate final 3D printed part. Raise3D’s full metal frame gives our printers a smoother movement. The beneficial combination of the metal frame’s accuracy and smoother movement results in a better 3D printed part. A better 3D printed part results in a better performing 3D printed part.

Industrial 3D Printers And 3D Printer Filaments

More than one 3D printing material, known as filaments, may be necessary to accommodate varying structural or functional requirements (some such requirements include flexibility, and strength). An industrial 3D printer will be designed to accommodate a wide variety of filaments to meet different kinds of project requirements.

One capability of an industrial 3D printer will be a higher nozzle and printer bed temperature. Higher nozzle and bed temperatures give the ability to print more materials and engineering plastics. Being able to accommodate more printing materials and engineering plastics will give the industrial 3D printer more uses, also known as applications.
