Media blasting, shot peening, isotropic superfinishing, electropolishing are processes we apply to improve both functional and aesthetic finishes.

Finishing

The surface roughness of a Selective Laser Melting part depends on the material, particles size, layer thickness, laser parameters, part orientation, as well as the presence of support structures.

Finishing might be required to smoothen surfaces, reduce surface roughness, clean internal channels or remove the partially melted powder. A variety of post-processes can help reduce the surface roughness of additive manufactured parts. Some techniques involve mechanical action (such as shot peening, tumbling and media blasting), whilst others involve the combination of both chemical and mechanical action (such as electro-polishing). Each method must be evaluated based on how well it works, how much material is removed, cost as well as the level of finish required.

Media Blasting is a surface treatment that forcibly propels a high-pressure stream of ceramic material against the surface of the part to smooth it.
The process provides a satin, uniform matte finish with approximately 2,5÷6,0μm Ra.

Vibro finishing can generate smoother exterior surfaces. This is a wet process that involves ceramic materials submersed in a surfactant compound. The process results in surface roughness between 0,8÷3,2μm Ra.

ISF® – Isotropic Superfinishing is a chemically accelerated finishing method developed by REM Chemicals, that generates a non-directional low Ra surface. The process is an ideal combination of chemical and mechanical surface finishing: by using accelerated refinement chemistries that are non-hazardous and environmentally friendly, a thin oxide layer is applied to the components, then removed by using ceramic abrasives. This creates a superfine finish (0,2÷0,8μm Ra), reduces friction and wear on the surface, increases part durability, and improves corrosion resistance.

We have all the equipment and machines in house to perform these surface treatments. Moreover, we have strong relationships with experienced third parties that can perform other finishing processes according to your specific requirements (i.e. electropolishing, anodizing, cataphoresis, varnishing, etc).
