VARIABLE BEAM GEOMETRY LASER-BASED POWDER BED FUSION

Systems and methods of adapting the geometrical shape of a laser beam in laser-based powder-bed fusion (PBF) are provided. An apparatus for laser-based powder-bed fusion includes a depositor that deposits a plurality of layers of a powder material. The apparatus further includes a laser beam source that generates a laser beam having a variable beam geometry. A laser application component applies the laser beam in one of a plurality of beam geometries to fuse the powder material to construct a build piece. 提供了调整基于激光的粉末床熔合(PBF)中的激光束的几何形状的系统和方法。用于基于激光的粉末床熔合的设备包括沉积多层粉末材料的沉积器。该设备进一步包括生成具有可变光束几何形状的激光束的激光束源。激光施加部件以多种光束几何形状中的一种来施加激光束，以熔合粉末材料来构造构建件。
