Are You Experiencing These SLS Production Challenges?

For many teams, the question is not whether SLS can make functional parts. The harder question is whether the process can support predictable production.

Unstable lead times: When an outsourcing partner or supplier changes their schedule, project milestones become reactive and delivery promises are harder to keep.
High communication overhead: Repeated requirement confirmations and back-and-forth around process limitations consume engineering time while the timeline stays uncertain.
Slow iteration: Every design revision has to wait for another outsourcing cycle, increasing trial-and-error cost and slowing new project development.
Unclear total cost: The quote may look reasonable at first, but rush fees, post-processing, rework, and coordination time often push the real cost beyond expectations.
Inconsistent quality: Batch-to-batch and supplier-to-supplier variation can lead to more assembly issues, extra inspection, and frequent rework.

Industrial SLS, Made Practical — Why RMS220

RMS220 is an industrial SLS 3D printer built on Selective Laser Sintering (SLS) for teams looking for an affordable SLS printer for repeatable batch production. Instead of positioning SLS as a one-off prototyping process, RMS220 is designed around a complete production workflow: job preparation, printing, Build Unit exchange, external cooling, depowdering, powder refresh, and post-processing.

In 30 Seconds: the Essentials

If your team is evaluating an SLS 3D printer, the decision is rarely only about machine specs. It is usually about whether you can make SLS production predictable enough for real delivery schedules.

Predictable Delivery Rhythm

Bring SLS production in-house with a workflow designed around Build Unit exchange, external cooling, depowdering, powder refresh, and post-processing, so teams can plan delivery schedules with more confidence.

Lower Cost per Finished Part

Reduce the hidden cost of outsourcing, rush fees, coordination time, rework, and inefficient powder usage. RMS220 is positioned to help teams build a more controllable cost structure for small-batch and production SLS parts.

Repeatable Part Quality for Functional Use

Produce parts with visible detail, stable surface quality, and functional material performance across validated nylon and TPU powders, supporting prototypes, functional prototypes, fixtures, and small-batch end-use parts.

Fine Detail without Sacrificing Production Rhythm

Support sharper edges, finer structures, cleaner surface details, and visible small-feature definition while keeping the workflow suitable for batch production.

FAQ

RMS220 is positioned as an affordable SLS solution for businesses, studios, and production teams—not as a personal desktop SLS machine. Compared with many industrial SLS systems, RMS220 offers a lower equipment entry cost, a more compact footprint, and an average material cost reduction of around 40%. These factors make it a more accessible way for professional users to bring SLS production in-house while still supporting a complete production workflow.

RMS220 is designed to bridge the gap between compact SLS systems and industrial SLS production. Compared with many small-format SLS printers, its advantages are mainly in part performance, speed, production capacity, and material flexibility.

First, RMS220 uses a 75 W fiber laser and a larger 220 × 220 × 350 mm build volume. Many compact SLS machines use 30 W or lower-power lasers, which can limit energy delivery, part strength, printing speed, and the ability to produce larger or batch-production parts. RMS220 is better suited for teams that need stronger parts, faster throughput, and the ability to print both batches and moderately larger components.

Second, RMS220 supports an open material strategy. Customers can choose a fully open-material version, which means they can work with selected or self-qualified materials without paying annual material authorization fees. This is important for companies that want to protect their product competitiveness, control long-term material costs, or use specific materials such as FDA-certified powders for regulated applications.

Dimensional accuracy in SLS is not a single fixed number. Even with leading industrial SLS systems, including EOS and other established platforms, accuracy is usually not published as one universal value—not because manufacturers are trying to hide it, but because SLS accuracy depends heavily on the material, geometry, nesting strategy, thermal behavior, and production workflow.

Similar to injection molding, the final tolerance comes from the combination of material behavior and process control. Flexible materials such as TPU can show more noticeable expansion or deformation, while PA11 may reach around ±0.1 mm on certain feature types and part geometries under suitable conditions.

For this reason, we help customers validate accuracy through sample printing. By testing representative parts, we can check real dimensional performance, identify which material is more suitable, and recommend the right process route for the application before moving into production.

Air processing can be possible for some materials and applications, but it does not always deliver the same surface yield as a controlled nitrogen environment. During SLS printing, oxygen in the chamber may react with powder while the material is being heated. In some cases, this can create visible burn marks or discoloration lines on the printed part surface, reducing the surface pass rate and increasing the need for sorting or post-processing.

This is why “air printing” should be understood carefully. A material may be printable in air, but the surface quality and production yield may be lower than when the same process is run in a nitrogen-controlled environment.

The built-in nitrogen generator helps reduce the need for external equipment in many common workflows. In many cases, customers do not need to purchase a separate nitrogen generator, which saves floor space, simplifies installation, and makes RMS220 easier to deploy in a compact production environment.

However, not every material has the same oxygen-level requirement. For materials such as PA11, or applications that require a lower-oxygen atmosphere for better forming stability and surface yield, users may still need an additional higher-capacity nitrogen generator to support the required process conditions.

For this reason, the nitrogen setup should be selected based on the material, target part performance, surface quality requirements, and production yield expectations rather than treated as one universal configuration for every application.

For most first-time RMS220 users, the recommended starter setup is not only the printer itself. A practical entry configuration usually includes 1 × RMS220 main printer, 2 × Build Units, 1 × Cleaning Station, 1 × blasting system, and 1 × vacuum / dust collection unit. This combination covers the basic production workflow: printing, Build Unit rotation, cooling, depowdering, powder recovery, and surface cleaning.

Two Build Units are important because they help keep the production rhythm moving. While one build is cooling or being depowdered, the printer can be prepared for the next job, reducing idle time and making the workflow more suitable for batch production.

If you need a better surface finish, polishing equipment can be added to the setup. Depending on the finish requirement, customers can choose between standard polishing and vibratory / mass-finishing polishing options.

If your local power quality is unstable, we may also recommend adding a UPS to help stabilize the power supply and protect the production process.

The final configuration should be selected based on your materials, production volume, surface finish requirement, facility conditions, and expected production schedule.
