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