How 3DPMolds uses the Raise3D DF2 to speed up low-volume injection molding

3DPMolds Background

3DPMolds is a company fully dedicated to the use of 3D printed molds in the development workstream of injection molders. More than a decade of hands-on experience has provided 3DPMolds an in-depth understanding of the factors that determine successful manufacturing outcomes.

Challenge: Ensuring Precision and Repeatability

As 3DPMolds expanded its mold production capability, maintaining consistent quality and process control across multiple iterations became a challenge.

• Each new resin and design requires different exposure, curing, and heating parameters.
• Mold lifetimes are short, sometimes just one or a few shots per mold, increasing the need for print process repeatability.
• Manual handling of files and settings increases the risk of errors during process setup.
• Any printer downtime can disrupt tight project timelines.

Solution: Adopting the Raise3d DF2

In early 2025, 3DPMolds adopted the Raise3D DF2 solution, a complete resin printing workflow that includes printing, cleaning, and post-curing systems. Optimized for high precision and repeatability, the DF2 features several elements particularly valuable for 3D printed mold manufacturing:

The DF2 system is optimized for industrial applications requiring precision and repeatability, providing:

• An open-material program that allows users to run certified third-party engineering resins to meet a diverse range of needs
• An integrated RFID workflow that links slicing, printing, washing, and curing data to each job
• A traceable workflow, ensuring that every process follows pre-defined parameters

Implementation: Traceable Workflow and Material Flexibility

With his background in the medical device industry, Lasse Staal was particularly drawn to the DF2’s focus on process control and traceability.

“I look for flexible manufacturing systems that help me drive down variation and ensure compliance with protocols. The DF2 solution is an open system that provides me with the flexibility to select the materials I want to work with as I develop a new mold manufacturing protocol. At the same time, it supports my compliance with manufacturing protocols by providing an integrated end-to-end data workflow that allows me to ensure that the process parameters defined in my protocol are applied at every manufacturing cycle, eliminating the risk that I inadvertently skip a step when I start a job. Also when I have to do a new round of manufacturing six months after the first job I did”.

The workflow that Lasse Staal refers to is built around the RFID-tagged build plate of the DF2 printer:

Using ideaMaker, parameters for printing, cleaning, and curing, such as chamber temperature, drying times, and curing intensity, are defined and stored on the plate. When the plate moves from printer to washer and then to the curing station, each machine automatically loads the correct parameters with a simple swipe over the RFID reader. This touch-free, traceable process not only improves consistency but also results in a much cleaner resin printing experience.

Results: Reliability, Flexibility, and Faster Iteration

Dedicated to staying at the forefront, 3DPMolds has taken full advantage of the DF2 features.

“The first thing we started exploiting was the open-materials capability of the DF2” says Lasse Staal. “While it comes with a set of pre-installed resins, we needed to set up profiles for the xMOLD and 3DPmolds IM 2.0 resins we routinely use in our manufacturing of complex molds. The off-the-shelf Idea-maker slicer that comes with the DF2 turned the set-up into a walk-in-the-park, providing us with all the handles we needed to dial in exposure times, light intensities, print speeds and chamber heating profiles.

Note: Access to the full ideaMaker DLP slicing settings requires prior approval.

The second thing noticed by 3DPMolds was the reliability and repeatability of the DF2 printer. “It took us a couple of weeks to realize what was missing” recalls Lasse Staal. “Normally, when I start up the run-in of my resins on a new printer, I expect to see a couple of failed prints at some point. But the DF2 started working straight out of the box, took everything I threw at it without missing a build”.

Reliability is of particular importance in the manufacturing of 3D printed molds. For one, applications are typically close to the domain of manufacturing, and printer downtime is not an option. Another complication is the extreme range of materials and designs, which makes it critical for 3DPMolds to be quickly able to establish a baseline. “We run in a lot of new materials – in mold designs that may change several times over the course of a one-week design cycle. The nature of 3D printed molds means that we are often down to one or a few shots per mold, and I therefore need to know that each mold I use is identical to the others, in order to build my molding parameters”.

On average, 3DMolds reports in a study conducted by Deloitte on average:

• 80% in cost
• 80% in time
• 75% Reduction in greenhouse gas emissions
