SPATTER REDUCTION LASER SCANNING STRATEGY IN SELECTIVE LASER MELTING

机译:选择性激光熔化中的减少散射激光扫描策略

摘要

An additive manufacturing system wherein a gentle sintering run on heat-fusible particles is followed closely by a selective laser melting run. The laser sintering run slightly sinters the particles and causes the particles to adhere to each other, but not necessarily deform and lose their original shape. The particles become connected via bridges between each other, which holds them in place. During the laser melting run, the powder melts in place, with minimum particle ejection or mobility, since the particles form a network of connected particles.
