UnionTech RSPro 800: Technical Overview
Laser & Light Engine
The RSPro 800 features a dual 355 nm Nd:YVO4 UV laser system with a maximum scan speed of 15 m/s: significantly higher than the 4–8 m/s typical of competing SLA systems. The RSPro 800X (announced Formnext 2025) introduces a four-laser configuration for further throughput gains at the same build volume.
Optics & Scanner
Dual galvanometric system with F-theta objectives covers the 800×800 mm aperture. Dual-laser configuration requires one stitching zone calibration; the four-laser 800X requires three independent CMM-verified stitching zones.
Platform & Z-Axis
Ball-screw Z-axis (vs.
Calibration: RSPro 800
1. Dual Laser Power: Measure independently; difference ≤2%; spot size verification at full 800 mm aperture.
2. Multi-Laser Stitching: CMM verification; offset ≤0.05 mm in stitching zones. RSPro 800X: three zones, 4–8 hr full calibration.
3. Ball-Screw Z Repeatability: Laser interferometer or dial gauge over 50 lift cycles; repeatability ±0.01 mm.
4. XY Absolute Accuracy: CMM matrix 800×800 mm, 25+ points; tolerance ±0.12%.
5.
Defects, RSPro 800
Stitching Seam (multi-laser), Lines in stitching zones → CMM calibration + power equalization + reduced speed in stitching zones.
Undercure at High Scan Speed: Soft zones at 15 m/s → reduce speed, recalibrate Jacobs parameters.
Panel Warping: Warping at 800 mm flat sections → angled orientation, lattice supports.
Recoater Streak: Horizontal bands from contaminated/damaged blade → inspect and replace recoater blade.
Use Cases, RSPro 800
Automotive Body Panels, Full-scale doors, bumpers, hoods in a single build without splitting.
Aerospace Components: Interior parts with certified aviation resins and ball-screw repeatability.
Production Tooling: Jigs and fixtures for production lines at ±0.12% accuracy.
Aerodynamic Models: SLA surface quality (Ra <1 μm) for wind tunnel testing.
