Sanding involves smoothing the surface of a printed part using sandpaper to remove layers of excess material, print streaks, and defects.

Coats of paint, varnish, lacquer or other coatings can be applied to the printed surface to improve its appearance, color.

Sandblasting involves blasting abrasive particles onto the surface to remove imperfections and create a uniform texture.

This involves covering the printed surface with a thin layer of metal by electrolysis. This adds conductive properties, better corrosion resistance and a metallic appearance.

Certain chemicals can be applied to modify the surface of the printed material, allowing smoothing, or giving it specific properties, such as hydrophobicity or adhesion.

It involves filling a 3D part with colored epoxy resin to obtain a perfect result.

Hydrography is a process where images printed on water-soluble film are transferred to objects by dipping them in water, creating decorative or textured designs.
