2014 Concept Laser M2 Series 3+ Metal Powder Bed Dual Laser Fusion 3D Printer

Key Features & Benefits:
Dual-laser system with overlapping scan fields for significantly faster build rates (up to ~80% productivity gain vs. single-laser equivalents).
Patented Laser USING® process with excellent inert-gas management and powder handling.
Open architecture for full process parameter customization.
Reliable for series production, functional prototypes, and complex geometries.
