Custom manufacturing is never a problem for DMLM. Many medium-sized to small-sized parts and inserts can be constructed in hours-and-days versus days-and-weeks using traditional prototyping processes.
After the Direct Metal Laser Melting process, the parts can be post processed (machined, welded, heat treated, polished, etc.), if desired, as any cast or billet material can be. In fact, the process yields parts with physical properties that fulfill the needs of final production parts and in cases of smaller volumes, DMLM is being used as an alternative to the traditional manufacturing processes.
By manufacturing the part with DMLM, it allows the engineer to optimize their design, because the traditional rules of “design for manufacturing” do not bound them. Direct Metal Laser Melting grow internal passages that curve, or multiple piece assemblies built as one.
