Directed Light Fabrication (DLF) was developed in the early 1990’s at Los Alamos National Laboratory. The original notion for the technology stemmed from solving joining issues in autogenous and dissimilar welds, where filler material was often used in the fabrication process. With the growing utilization of CAD and CNC technology, the goal was to fuse gas delivered metal powders within a focal zone of a laser beam to produce fully dense, near-net shape, 3-dimensional metal components from a computer generated solid model. Over the next decade, the technology evolved to 5-axis control, and parts from aluminum to tungsten were fabricated, including many intermetallic systems (even from elemental blends). Solidification studies indicated continuous liquid-solid interfaces with cooling rates from 100 K/s to 100,000 K/s, and mechanical properties were comparable to conventionally processed commercial product. Cost, surface finish, and component qualification issues ended the DLF process in the early 2000’s.
