- [Female Instructor] There's several ways to 3D print metal that involve metal powder; with or without a binder. In this movie, we discuss what types of parts are most appropriate for the different processes, which include direct metal laser sintering, or DMLS, binder jetting, and processes that use filament. - [Male Instructor] Direct metal laser sintering, or DMLS, uses a laser to sinter very fine powder. The technology's expensive because the fine metal powder it uses requires protective equipment for staff handling the material. Printing typically happens in an inert gas atmosphere to prevent oxidation. It does have the virtue that everything happens in one step. The print comes off the printer fully sintered, though it may still require annealing to relieve internal stresses. Powder based 3D printing with nylon or similar plastics does not need support, since the power provides the support. However, DMLS needs support.…
