Industrial SLS 3D Printer for Batch Production
The Raise3D RMS220 brings production-grade SLS in-house, combining:
- speed
- productivity
- repeatability
- ease of use and maintenance
To meet the needs of design offices, workshops, manufacturers and R&D teams. Supplied with its Build Unit 220, the RMS220 processes engineering plastics and composites and reaches a throughput of up to 5 kg of parts per day at full capacity, making it possible to produce end-use parts efficiently.
Key Technical Specifications

- Build volume: 220 × 220 × 350 mm (17 L)
- Laser: 75 W infrared fiber laser, 1064 nm
- Printing speed: up to 2.2 L/h (20% packing density by weight)
- Layer height: 0.05 – 0.40 mm
- Connectivity: Wi-Fi, Ethernet, USB with real-time camera
Advanced Technical Performance
High-speed laser system
The RMS220 is equipped with a 75 W, 1064 nm fiber laser and an industrial-grade, high-precision galvanometer with a scanning speed of up to 30,000 mm/s. This combination suits both intricate prototypes and high-throughput batch production. A 4-zone self-calibrating IR heating system limits dimensional deformation across the build platform, for consistent and repeatable results. Preheating starts during slicing, so the printing temperature is reached within about 20 minutes.
High-efficiency batch production
With a 220 × 220 × 350 mm (17 L) build volume, the RMS220 supports multi-part builds and high nesting efficiency, delivering up to 5 kg of functional parts per day (PA12, standard parameters, 20% packing density by weight). For fine details, the printer can reach a minimum wall thickness of 0.5 mm in thin-wall mode (requires technical support from Raise3D).
Extended material compatibility
The RMS220 prints a range of industrial and functional SLS powders:
- Raise3D PA12: general-purpose material, easy to print, with balanced mechanical performance and high accuracy
- Raise3D PA12 GB: improved stiffness and temperature resistance, higher modulus and HDT, matte black finish
- Raise3D PA11: tough material for impact-resistant parts, snap-fits and soft hinges, suited to thin walls and fine structures
- Raise3D TPU 90A and TPU 86A (black or white): strong, elastic and durable elastomers for flexible functional parts
Through the Open Material Program (OMP), selected third-party materials are also supported, and an optional fully open material license is available.
Industrial Design and Workflow
Build Unit 220 and External Cooling
The Build Unit 220 is an independently powered module designed to maximize uptime. Its vertically movable build cylinder allows smooth handling and faster cooling without damaging parts. The unit cools down to below 100 °C in about 30 minutes, so cooling takes place outside the printer. With a second Build Unit, the next print can start immediately.
Quick-Detach Modular Design
Material switching is reduced to about 45 minutes, roughly one third of the time of a traditional SLS process. The system can be cleaned thoroughly with no hard-to-reach areas, for flexible use of different powders.
RFID Powder Management
The integrated RFID system automatically identifies and configures the powder in use, which simplifies material management and helps ensure part quality.
Powder Handling with the C220-P Cleaning Station
The Raise3D C220-P cleaning station semi-automates powder separation, recovery and preparation. Each print cycle requires only 20 to 45 minutes of labor, and one operator can process more than 50 kg of parts per shift.
Large Build Volume, Compact Footprint
Despite its build size, the RMS220 occupies only 0.58 m² of floor space. A built-in nitrogen generator supplies the protective atmosphere (compressed air required), with no need for gas cylinders in common workflows.
Ergonomics and User Experience
Interface and Connectivity
Equipped with an 11.5-inch touchscreen, Wi-Fi, Ethernet and USB connectivity and a real-time camera, the RMS220 makes it easy to monitor prints. Jobs are prepared in the ideaMaker software (STL, OBJ, 3MF, OLTP, STEP, STP, IGES, IGS), including part positioning and nesting to optimize density, print time and material use.
Comfort and Safety
An adjustable elbow rest reduces fatigue during cleaning, a transparent protective cover keeps the work area visible and safe, and a HEPA and activated carbon filter is built in.
Applications
- Functional prototypes and design validation
