Beam shaping with multi-plane light conversion to increase the process speed in laser powder bed fusion

Laser Powder Bed Fusion (LPBF) is a critical additive manufacturing process known for its accuracy and complexity in producing intricate parts. However, challenges like limited production speed, hot cracking, and material restrictions hinder its efficiency. This study explores the use of Multi-Plane Light Conversion (MPLC) as a beam shaping solution to improve LPBF. By applying MPLC, we achieve faster printing while maintaining high-quality parts. Comparative analysis demonstrates the superiority of MPLC-based beam shaping in enhancing process yield and manufacturing efficiency.
