Colibrium Additive M Line: Technical Overview
Laser System
Four Yb fiber lasers (~1070 nm) rated at 4 × 400 W (standard) or 4 × 1 kW (2024 upgrade for non-reactive materials). Each laser operates with an independent 2-axis galvanometer scanner; overlap zones are managed by the Colibrium Build Processor for smooth stitching.
Platform and Build Volume
Build envelope 500 × 500 × 400 mm: among the largest LPBF platforms in serial production. Modular architecture: build module (printing), processing station (depowdering and cooling), and setup station (next-job preparation) operate independently, minimising machine downtime.
Protective Atmosphere.
Calibration Protocol: M Line
Multi-Laser Calibration
All four scanners are calibrated independently and then verified in overlap zones. Use the official Colibrium calibration kit; recalibration is mandatory after laser module or optics replacement.
Powder Bed
At 500×500 mm, small recoater deviations are visible. Recommended powder D50: 25–45 µm; inspect recoater blade daily in production mode.
VED per Material.
Common Defects: M Line
Overlap Zone Porosity
Mismatched laser parameters in scanner overlap zones cause bands of elevated porosity. Solution: precise overlap zone calibration; use Colibrium-approved multi-laser parameter sets.
Hot Cracking
Typical in IN718 and IN625 for thick walls. Solution: preheat platform; optimise scan strategy; HIP + aging post-print.
Distortion and Build Plate Detachment
Significant residual stresses at the 500×500 mm scale.
Use Cases: M Line
Aerospace Serial Components
500×500 mm allows production of entire engine sections or hundreds of small parts in a single job; qualified to GE Aviation standards for Ti-6Al-4V and IN718.
Medical Implants
Hundreds of orthopaedic Ti-6Al-4V ELI implants in a single job: maximum throughput for a medical manufacturing facility.
