Supports are employed in 3D printing when the 3D model being printed features critical angles, overhangs, or intricate geometries that may collapse during the deposition of the still-viscous silicone (thin walls, tall stems…).

Supports are temporary structures that provide a stable foundation for the critical parts of the object until curing takes place. Once the cross-linking process is complete, the supports can be removed, leaving the final part in silicone with clean and accurate details.
