What is metal 3D printing? 3D Metal printing is a revolutionary technology that produces “impossible-to-make” end-use metal parts directly from your CAD data. The mechanical properties of DMLM parts are comparable to cast parts or machined component. The advantage of the process is that the more complex or feature rich the component, the more economical the process becomes. 3D metal printed parts are fully dense, incorporating complex geometries and precise internal features that cannot be made with traditional machining alone. Designs can be made quickly with a minimum of material waste while maximizing strength, making them ideal for next-generation applications in aerospace, medical, automotive and other industries.
