Powder Bed Preheating in 3D Printing
Efficient powder bed preheating is essential for reducing thermal stress and improving build quality in metal additive manufacturing. Photonics solutions play a key role by delivering uniform, high-power laser energy across large working areas.
Focuslight's customized beam shaping systems are designed for both single and multi-laser preheating configurations, featuring off-axis beam shaping, compact design, and high integration flexibility. Our system projects a large spot up to 300 x 300 mm with >90% uniformity at a max. 25° incident angle, rapidly heating the powder bed up to 600°C, significantly improving the efficiency for high-precision metal 3D printing process.
