Silicone was the first material printed by the prototype 3D-Bioplotter in 2000.
This very versatile material can be used for numerous demo applications: from trying out new shapes and patterns using a cheap material; through making technical parts (e.g. gaskets); to medical device casings.
There are also many medical applications for silicones: from soft implants (e.g. ears, noses, breasts); through wound dressings; to surgical planning models, amongst others.
With curing directly during printing using UV, this medical grade silicone (USP Class VI) is mainly aimed at research applications as well as direct skin contact for a maximum of 29 days. This silicone displays low shrinkage, a medium hardness around 60 Shore and has no smell. By adding LSR color pastes prior to printing, the transparent material can be colored to the specific application requirements.
