What Is 3-D Metal Printing?


Quick Answer

In 3D metal printing, parts are manufactured by a laser fusing together high-performance metals, layer by layer. This process is also known as Metal Additive Manufacturing or Direct Metals Laser Sintering.

Full Answer

3D metal printing uses a laser beam to melt 20 to 40 micron layers of metal powder on top of each other. Similar to other forms of 3D printing, metal printing uses metal powder that is spread and melted across a building platform instead of extrusion of plastic filament. Produced directly from 3D CAD data, parts are strong and lightweight with complex internal features such as internal voids, undercuts, tubes within tubes and channels through sections. It is a fast, accurate and cost-effective method for the production of one-off prototype components. Parts created using this method are dense and have excellent mechanical properties.
