Raise3D RMS220

The Raise3D RMS220 is an SLS 3D printer from Raise3D with a 220 x 220 x 350 mm build volume.

Specifications

Laser: 75W (type unspecified by manufacturer, likely CO₂ or fiber); significantly more powerful than compact SLS systems (14–30W), enabling higher scan speed and throughput.

Scanner: Galvanometric system; four-zone self-calibrating IR heating system covers the full 220×220 mm build area.

Platform: Build platform 220×220 mm; Z travel 350 mm; swappable build chamber (~45 min. swap time).

Chamber: Active thermal enclosure with four independent IR heater zones; slow-cool profile for PA12/PA11; programmable material profiles.

Build Volume: 220×220×350 mm; build rate 2.2 L/hr at 20% fill density; up to 5 kg PA12/day.

Calibration

IR zone calibration: Self-calibrating system balances four zones after each chamber swap; verify ±2°C homogeneity across build area.

Laser optimisation: Test artefact at 60–75W with various scan speeds for PA12/PA11; 75W provides headroom for faster scan speed vs. 14W CO₂ systems.

Chamber swap procedure: ≤45 min.; verify Z-axis alignment and recoater position after installation.

Common defects

Orange-peel: Cold chamber or unbalanced IR zones → recalibrate + extend pre-heat.

Warping: Fast cool-down → slow-cool ≥2°C/min; ≥15 mm powder around part.

Recoater streak: Contaminated/scored blade → clean or replace; check previous layer.

Porosity: Low power/high scan speed or degraded powder → adjust ED or replace powder batch.

What it is used for

Small-batch PA12 production: 2.2 L/hr and 5 kg/day: highest throughput in class under €35k.

Modular continuous production: 45-min chamber swap = near-zero downtime between builds.

PA11 medical/sports parts: Good ductility and validated profiles for biocompatible applications.
