¶ RMS220 Related FAQ
1. What type of laser is used?
75W fiber laser with a wavelength of 1064 nm. Competitors typically use lasers averaging 10–30W; higher power enables faster printing and broader material compatibility.
2. What is the laser spot size?
##0.2 mm##. This size strikes an optimal balance between print speed and detail resolution: too small reduces efficiency, while too large compromises fine features.
3. What is the scan speed (galvo speed)?
Up to 30,000 mm/s. Competitors average around 15,000 mm/s, with top models reaching only 20,000 mm/s. Equipped with high-performance industrial-grade galvanometers for significantly improved efficiency.
4. What is the maximum chamber temperature?
Up to 220°C (competitors average ~200°C), enabling stable sintering of advanced engineering materials such as high-temperature nylons or composite powders.
5. What is the actual usable build volume?
The nominal build volume of 220 × 220 × 350 mm represents the net usable space, already accounting for safety margins. While the physical chamber is slightly larger, exceeding this range may compromise print quality or feasibility.
6. What are the N₂ (nitrogen) supply requirements?
Peak flow rate: 15 L/min; average flow rate: 7.5 L/min; pressure range: 0.1–0.9 MPa.
7. Does powder recoating use a roller or a blade?
A roller is used for powder spreading, ensuring uniformity and repeatability.
8. What is the material hopper capacity?
Internal hopper capacity is 31.5 L; with the C220 material cartridge expansion, it reaches 40 L—sufficient for full-chamber prints.
9. What are the power requirements?
Single-phase power supply supported; a dedicated circuit is recommended. Peak power consumption: 2800 W; average: ~1000 W.
10. What equipment is needed to run a complete SLS system (e.g., RMS220)?
- SLS 3D Printer: e.g., RMS220, for laser sintering powder into parts.
- Cleaning Station: e.g., Raise3D C220-P Powder Cleaning Station, for safely extracting parts from the “powder cake” and recovering unsintered powder. Manual cleaning is inefficient, wasteful, dusty, and risks damaging electronics.
- Blaster: e.g., Raise3D B520 (recommended but optional), for deep cleaning and light surface finishing to significantly enhance part quality.
- ATEX-Certified Industrial Vacuum: e.g., Delfin 301, designed specifically for ultrafine powders. Household vacuums must never be used—they can be damaged or cause hazards.
- Nitrogen Supply: Not mandatory, but improves print speed and part quality. Options include nitrogen cylinders (low cost but cumbersome) or nitrogen generators (more convenient, starting at ~$5,000–$6,000).
- Air Compressor System: Atmosphere Mode: Air Mode/Nitrogen Mode (RMS220 has a built-in nitrogen generator; compressed air is required).
Recommended nitrogen mode parameters: Pressure 0.1-0.8 MPa, flow rate ≥ 20 SLPM, purity ≥ 98%.
Recommended compressed air parameters: Pressure 0.5-0.8 MPa, flow rate ≥ 20 SLPM. Inlet air must be oil-, water-, and dust-free. We recommend installing a three-way fitting. - Personal Protective Equipment (PPE): N95 or higher-grade respirator and safety goggles are recommended to prevent inhalation or skin/eye irritation from fine powder.
11. What is the turnaround time between two prints?
- With an extra Build Unit 220: Turnaround can be kept under 1 hour.
The printer features optimized internal airflow to minimize airborne powder, reducing contamination on viewports and laser optics. Dedicated service ports allow rapid maintenance of optical and critical components. - Without an extra Build Unit 220: The “powder cake” must cool naturally to room temperature before depowdering and cleaning—typically 6–8 hours, significantly extending downtime.
12. How long is the downtime when switching materials?
- With an extra Build Unit (Build Unit 220): Material change and system cleaning can be completed within 1 hour, enabling highly efficient workflows.
- Without an extra Build Unit 220: The entire print chamber must be thoroughly cleaned of residual powder and dust, which takes considerably longer depending on cleanliness standards and operator experience.
13. Can the RMS220 produce end-use parts?
Yes. Thanks to its excellent mechanical properties, material stability, and support-free design, SLS is widely used to directly manufacture end-use parts, especially for low-volume, customized, or geometrically complex applications. Examples include:
- Fluid ducts in automotive systems
- Custom orthotics in healthcare
- Wear-resistant gears or connectors in industrial equipment
As long as the chosen material meets the application’s environmental requirements (e.g., temperature, load, chemical exposure), SLS parts are fully suitable for final-product use.
