3D-priting comes with crucial advantages. Complex geometries which are hard to realize with other methods of production can be easily produced. Complex undercuts, re-entrant angles, hollow spaces and drilled holes that change directions can be realized in the geometry of the silicone product.
Additionally, 3D printing can drastically reduce production time due to the fact that you can produce a prototype without a tool.
Also in the area of Rapid Prototyping, 3D-printing adds additional value: Geometries can easily be changed digitally via a CAD-Software and the resulting tool is quickly printed again. Therefore, the time required for prototyping of silicone products as well as the cost and risk are significantly reduced.
