Post-processing on plastic additive manufactured parts

Pieces and components made of plastic material lend themselves to various post-processing treatments and finishes aimed at obtaining excellent aesthetics, particular effects or specific technical and functional characteristics.


For technologies that require it, such as stereolithography, the post-extraction phase begins with the removal of the supports, for other technologies it starts by simply cleaning the pieces extracted from the machine. Afterwards, a uniform surface is obtained by using special treatments such as micro-shot peening and sandblasting.   [ Learn more ]


Out of all the possible finishes, without doubt painting is the most common post-processing activity and can be used in a multitude of cases. Painting allows you to establish a series of characteristics including the colour, from RAL or Pantone, the level of finish, glossy, matt or embossed, and other specific parameters.

Smoothing considerably reduces surface roughness of the piece achieving the values required for the project and can also be used to prepare the substrate for an aesthetic paint finish. Polishing is crucial when the prototype must be transparent as in the case, for example, of a light guide.

Vacuum metallising allows the piece to be coated with a thin layer of metallic material, making the surface metallised; successful metallising requires good preparation of the substrate.

Aesthetic finishes available for pieces made of plastic material include flocking, soft-touch, screen printing and pad printing, laser-etching, PVD and sputtering.

For some materials it is possible to carry out a special treatment to make the piece water-repellent. Other examples are copper plating and metal encapsulation.    [ Learn more ]
