About silicone

Silicone is a biocompatible elastomeric polymer with excellent mechanical and chemical properties. The ability of 3D printing industrial parts in real silicone is one of the major technological breakthroughs in the additive manufacturing world of the last 5 years. Until recent years, the alternative was to use either injection molding or other materials that attempted to mimic the rubber-like properties of silicone.

Silicone is an extremely versatile material with unique properties that can be used for many high-performance applications due to its resistance to extreme environments. For instance, 3D printing in Silicone enables the creation of end-parts with a high degree of flexibility and precision that can be sterilized. It can withstand high extremes, it offers good electrical resistance and the possibility of printing parts with different levels of elasticity.

In comparison to injection molding, 3D printing offers a higher degree of customization and enables the production of parts that are higher in complexity. For those reasons, silicone printing is very popular in the automotive and medical industries.
