Product Description
The rubber molding resin has a high hardness and strength, and also has a very smooth surface. It can be used for ordinary silica gel to continue to heat at high temperatures, then to be a prototype of silica gel mold, instead of silver mold.
High definition, strength and precision
Capturing complex details without worrying about features that are too small to print, it is ideal for small holes and fine pins, and it also can create challenging and unique models.
Smooth surface quality
No need to polish, the printed model with a smooth surface can achieve perfection with minimal polishing.

Frequently Asked Questions
Q: What is 305S silicone mold resin used for?
A: 305S is a 3D printing resin formulated to create hard, dimensionally accurate master patterns for making silicone molds. Printed masters are cast in silicone to produce reusable molds for wax, resin or urethane casting.
Q: How do you print with 305S resin?
A: Print it on any 405 nm LCD, DLP or SLA printer at typical layer heights of 25-50 µm. After printing, wash with isopropyl alcohol and post-cure in UV for 1-5 minutes to reach full hardness.
Q: Can 305S masters be used for production silicone molds?
A: Yes. Its low shrinkage and smooth surface keep mold cavities precise over many pours. The rigid, cured master releases cleanly from platinum- or tin-cure silicone.
Q: Is 305S resin meant for direct lost-wax casting?
A: No. 305S is a model/master resin, not a burnout casting resin. For direct investment casting you should use a dedicated casting or white wax resin designed to burn out with minimal ash.
Q: What resolution works best for 305S?
A: Print at 25-50 µm layers to balance detail and speed; finer 25 µm layers capture more surface texture for high-detail jewelry or craft masters while keeping polishing to a minimum.
