About SH3D Factory
SH3D Factory SA is a company specialised in the design, engineering and manufacture of parts and products, based in Les Acacias near Geneva. Its service portfolio covers the additive manufacturing of prototypes and series using 3D printing with SLS and FDM processes, as well as the post-processing of printed parts through chemical smoothing, in which a solvent vapour smooths the surface of nylon parts without altering details or geometry. In addition, the company offers UV printing on substrates such as glass, wood and metal, as well as laser engraving and laser cutting with a 55 W CO₂ laser for materials such as wood, acrylic and leather. The machine equipment allows it to handle a broad spectrum of requests, from one-off pieces to series production. Visits to the site at Rue François-Dussaud 17 are only possible by appointment.

Materials & Processes
Nylon
Material for SLS 3D printing; printed parts can subsequently be chemically smoothed.
UV printing
Printing process with inks that cure instantly under UV light, for substrates such as glass, wood and metal.
CO₂ laser (55 W)
Contactless engraving and cutting of wood, acrylic and leather with high precision.
Chemical smoothing
Manufacturing process using solvent vapour that smooths the surface of 3D-printed nylon parts.
