Models made in titanium are printed in titanium powder that is sintered together by a laser to produce end-use metal parts that are as equally good as machined models. 3D printed titanium (unpolished) doesn’t look like the traditional shiny milled titanium. Instead it’s a bit grayer and more matte with a slightly rougher and less defined surface. Models in titanium are very strong, precise and can have feature size as small as 0.25 mm.

The technique used to build your design with titanium is direct metal laser sintering (DMLS). It's similar to the selective laser sintering technology but instead of polyamide, a fine metal powder is used build your model layer by layer. The powder is sintered and solidified by a laser beam that moves over a box filled with powder in minute layers. After each layer a new layer of powder is applied. Your intact model is then lifted from the powder bed. If your model needs support structures to keep the model structurally sound or to support it while the 3D printer builds it, the titanium support structures have to be removed manually.
