Standard silicone formulations are optimized to be used by extrusion and injection moulding machines and are not applicable in LDM-based 3D printing. The rheological behavior and the pot life need to be adjusted for use with LDM. [12] 3D printing also requires the use of a removable support material that is compatible with the silicone rubber.

RTV silicone rubber can be used to cast materials including wax, gypsum, low-melt alloys/metals, and urethane, epoxy, or polyester resins (without using a release agent). A more recent innovation is the ability to 3D print RTV silicones.
The mold is created via a master pattern. Master patterns for cast urethanes can be created with CNC machining (which is a common process for injection molding) but cast urethane master patterns are often created with additive manufacturing (or 3D Printing) and the reasons for this vary.
A custom resin cast Pinky:St part and two-part silicone mold. Resin casting is used to produce collectible and customized toys and figures like designer toys, garage kits and ball-jointed dolls, as well as scale models, either individual parts or entire models of objects like trains, aircraft or ships.
Injection molding of liquid silicone rubber (LSR) is a process to produce pliable, durable parts in high volume. Liquid silicone rubber is a high purity platinum cured silicone with low compression set, good stability and ability to resist extreme temperatures of heat and cold ideally suitable for production of parts, where high quality is ...
