Additive Manufacturing is a printing technique for metal components starting from pure metal powder. Untreated AM components are often characterized by a little rough and grainy surfaces from 5µ to 10µ Ra roughness. Therefore LayerWise developed its SILC TREATMENT to improve the surface quality.

The list belows give a short summary of available surface finish options:

• SILC BASIC: a matte, uniform finish (Ra 4-7 µ)
• SILC MEDIUM: a uniform finish (Ra 2-3.6 µ )
• SILC POLISH: a smooth, shining finish (Ra 0.8-2 µ)
• SILC HIGH POLISH: a smooth, mirror finish (Ra 0.05-0.8 µ)
• SILC ELECTROPOLISH: a shining finish that makes it easy to clean parts
• SILC CLEAN: for particle free components in high demanding applications
