The M660G, with a 660*660*1300mm build size and 1.2m printing height, leads in large-scale pure copper and copper alloy 3D printing. Equipped with four self-developed single-mode green fiber lasers and precision optical calibration, it ensures high accuracy and consistency.
Its small spot diameter enhances detail, while advanced multi-laser stitching keeps performance variation under 5%, boosting stability. Bidirectional recoating and thick-layer green laser technology achieve speeds of 65-140 cm³/h.
Designed for long-term, high-load operation, it excels in producing large, high-quality pure copper and alloy parts, ensuring efficient, reliable 3D printing.
