A versatile, high HDT master pattern material for jewelry silicone molds and high visualization detailed prototypes of complex and fine designs.
Stunning surface finish and high definition for jewelry pieces prototyping and production with RTV/silicone molding.Figure 4 JEWEL MASTER GRY is a versatile master pattern material for high volume jewelry RTV/silicone molds and for prototype/fit models. The material’s high heat deflection temperature (300°C) ensures compatibility with a range of silicones for creating molds used in jewelry casting production workflows.
This material also delivers exceptional precise surface quality for design and functional prototyping, as well as snap-fit and stone-in-place testing. Figure 4 JEWEL MASTER GRY meets biocompatibility standard ISO 10933-5 for cytotoxicity, making it safe for try-ons and fittings.

General Tips
General Best Practices apply.
- The most important factor to ensure printing success is getting the supports correct.
- Check the catch-tray glass inside the printer often and clean as needed.
- Pour unused print material through a paint strainer funnel to remove any print debris to keep material in optimal condition. Follow the recommendations here for funnel usage.
- Use the JEWEL MASTER GRY Master Pattern support style with the 30µm Master Pattern print mode to print high-resolution, master-pattern parts.
- Use the JEWEL MASTER GRY ProtoType support style with the 50µm ProtoType print mode to quickly print lower-resolution prototype parts.
- The JEWEL MASTER GRY print modes are optimized for jewelry type parts. These print modes may not be reliable for large, non-jewelry type parts. Increase cure depth as needed to avoid delamination between layers. Add 1-2 seconds to the Interval Pause Time and the Interval Down Time values to improve printing reliability. Use the general purpose support styles instead of the jewelry support styles for non-jewelry type parts.
