Printing Process

Selective Laser Melting (SLM):
Selective laser melting (SLM) is a metal additive manufacturing (AM) technology that uses a bed of powder with a source of heat to create metal parts.

Laser Solid Forming (LSF):
Laser solid forming (LSF) is a typical laser direct energy deposition additive manufacturing technology based on the powder feeding method with a high deposition rate.

Wire Arc Additive Manufacturing (WAAM):
Wire arc additive manufacturing (WAAM) is a wire-based DED approach that uses an electrical arc as a source of fusion to melt the wire feedstock and deposit a part preform, layer by layer.

The BLT Intelligent Manufacturing Factory is equipped with 380 sets of machines and systems, with nearly half of them being large-format systems. The build dimensions of the large-format systems range from 400mm to 1500mm, while the build dimensions of the small and medium-format machines and systems range from 160mm to 400mm. Machines and systems of all sizes are capable of meeting the manufacturing requirements for various aerospace parts.
