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.
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.
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.
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.
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.
Support sharper edges, finer structures, cleaner surface details, and visible small-feature definition while keeping the workflow suitable for batch production.
Compare SLS Powder Properties Not sure which SLS powder to start with? Use this hub to quickly check whether each material can cover your needs—color options, oil resistance, heat resistance (HDT), toughness / flexibility, and small-feature detail—then shortlist the right powder before requesting sample parts or discussing a production case.
Raise3D support real production and engineering workflows across multiple industries. Our service and solution experience includes customers such as CATL , Advantech，Schaeffler , among others.
This is a full blog article with a complete cost model. Use the 100 kg finished-parts reference scenario to compare outsourcing vs in-house RMS220, and Industrial SLS vs RMS220—covering cost per part (including material cost, labor, energy, depreciation, and key consumables)
A clear path from evaluation to stable production. We guide you step by step: first validating feasibility with sample parts, then deploying the system together with the local reseller. Many of our reseller partners have worked with Raise3D since 2015, helping ensure long-term, localized service and reliable after-sales support.
Use these examples as reference scenarios to discuss your own production case with an SLS expert. Actual cost per finished part depends on material price, powder refresh ratio, packing density, labor, energy, depreciation, post-processing, and part geometry.

Not sure whether in-house SLS makes sense for your parts? Share your application, target quantity, material needs, and finishing requirements with our experts. We’ll help you review the key cost drivers, workflow considerations, and whether RMS220 is a good fit for your production goals.
RMS220 is designed to keep SLS production moving—from part preparation and build packing to printing, external cooling, depowdering, and post-processing. With a 220 × 220 × 350 mm build volume, Build Unit switching, and a workflow built around parallel cooling and powder handling, teams can reduce downtime between jobs and improve batch production efficiency.
Import files, nest parts, set packing density targets, and confirm material settings.
Run high-speed scanning with a stable process window for repeatable builds.
Use Build Unit switching and external cooling to reduce printer idle time.
Separate parts from powder and prepare reusable powder for the next cycle.
Use blasting, polishing, or other post-processing options for the required surface finish.
Follow between-build maintenance steps to protect repeatability and production rhythm.
The main laser processing system. It handles the core SLS printing process, including laser sintering, scanning, heating control, and print-job execution.
The removable powder/build chamber. For each new job, teams can exchange the Build Unit and then moves through the workflow for cooling, depowdering, powder recovery, and preparation for the next build.
Supports powder separation, recovery, and preparation for the next build.
Supports surface finishing for end-use, presentation-ready, or dye-ready parts.
Large-format SLS systems often need careful scheduling because teams may wait to fill a full build before starting a job. RMS220 helps teams keep production moving with a more flexible build strategy for both batch production and smaller urgent jobs.
For large SLS builds, cooling can often become the bottleneck. RMS220 targets a shorter cycle rhythm with a 12-hour cooling cycle, compared with the 18–24 hour cooling cycle commonly seen in larger-format workflows.
For prototype or validation parts, PA NEXT with sandblasting can often deliver a usable surface finish without requiring extended downstream finishing (such as dyeing, coating, or intensive polishing).
With SLS batch nesting, Build Unit switching, and external cooling, RMS220 can deliver far more finished parts per cycle than typical FFF/FDM setups—so you can meet production demand without running multiple printers in parallel.
Clear the powder hopper and switch materials within ~1 hour for rapid print trials—ideal for universities, labs, and R&D teams that need to test different powders and run small-batch production without long changeover downtime.
Smoother look and better hand feel, close to well-finished nylon or injection-molded parts; a strong choice for visual prototypes, fit-check models, and functional prototypes that need a more refined surface finish.
Glass-bead reinforced nylon with better toughness and structural stability; suitable for structural prototype testing, functional validation, fixtures, and parts that need stronger performance while keeping the refined PA NEXT surface quality.
Better suited for fine-detail structures with added toughness; ideal for high-precision parts such as electronic components, connectors, orthotic insoles, snap-fit features, and functional parts that need both detail and durability.
Flexible elastomer for applications that interact with people or objects; suitable for factory soft grippers, humanoid robot shells, prosthetic components, protective padding, footwear, and other flexible functional parts.
Flexible elastomer with slightly better toughness than TPU 86A; suitable for bending applications, flexible functional parts, protective components, and parts that need repeated deformation or impact resistance.
High-performance nylon material with good dimensional accuracy; suitable for general-purpose small-batch production parts, including complex components such as automotive intake manifolds and other parts that require reliable assembly tolerances.
Glass-bead reinforced PA12 with higher performance and better HDT heat resistance than standard PA12; a preferred material for small-batch production parts and for replacing low-volume nylon injection-molded components that need stiffness, dimensional stability, and reliable performance.
