Making a Platinum Silicone Mold of an SLA Printed UV-Cure Model

Making rubber molds and multiple castings of 3-D prints made with SLA is often a goal of model makers. As 3-D printing technology using SLA resin continues to evolve, there are best mold making practices that can help you be successful.

Platinum silicones offer the advantage of dimensional stability and long-term library life. However, platinum silicones are more subject to cure inhibition against a UV cure resin model that is not fully cured.

Smooth-On platinum cure silicones will work against most SLA 3D print models with one caveat; the printed model must be fully UV cured. When models are done printing, they are not fully cured.
