摘要: Directed Light Fabrication (DLF) is a rapid prototyping process being developed at Los Alamos National Laboratory to fabricate metal components. This done by fusing gas delivered powder particles in the focal zone of laser beam that is, programmed move along or across part cross section. Fully dense built up layer time form desired represented 3 dimensional solid model from CAD software. Machine ``tool paths`` are created command movement and processing parameters specific DLF so can be one time. The result fully dense, near net shape solidifies under solidification conditions.
