The coloring of your parts in additive manufacturing

Dyeing is today a real alternative to painting for the coloring of your parts. It can be used on parts made from powders (Sintering, Multi Jet Fusion HP) as well as on parts made from liquid resins (Stereolithography, Polyjet, vacuum casting). The result is amazing, it can quickly give a deep and uniform color to your parts. Here are some elements that will help you choose between the two.

It allows to obtain all the colors of the RAL color chart. It is applied with a spray gun on a part or all the part. There is no limit to the size of parts that can be prototyped. It is available in a variety of finishes: matte or glossy but also with a grained effect. It is necessary to take into account the extra thickness obtained after application.

The choice of colors is limited and the size of the pieces cannot exceed 400 mm in length, 250 in width and 100 mm in height. The pieces are dipped in a dye bath, then drained, rinsed and dried. The pigments penetrate deeply and completely into the walls of the part, which guarantees a better resistance to abrasion.
