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.

Typical Use

Aluminum can be used for full functional parts, spare parts and jewelry.



The technique used to build your design with Aluminum 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 aluminum support structures have to be removed manually. 

Additional Information

  • This is a Trial Material. Since it’s experimental, design rules or pricing can be subject to change as we learn more about this material.
  • It's possible to make non-rectangular, organically shaped objects that are not able to be produced by any other process.
  • Because supports have to be removed manually, some evidence of removed support structures might remain on your model.
  • Any “overhanging” structures such as the bottom of a table built with this process will tend to be unattractive.
  • Any angles less steep than 35° will tend to be less attractive with this process.
  • The most ideal shape to make with this process is that of a “mesh with holes”. This makes it easy to design with this process and delivers the best results.

Sample Kit

Learning about our materials is one thing, seeing and touching them another. That's why we've designed sample kits based on our Periodic Table of Materials.
