Formlabs is excited to announce Castable Wax 40 Resin, our new resin for direct jewelry investment casting. Formulated from the ground up, Castable Wax 40 Resin is highly loaded with a blend of solid and liquid waxes that work together to achieve low expansion and exceptional casting performance. 

With this resin, we have combined industry leading castability with the intuitive workflow Formlabs is known for. Castable Wax 40 Resin is a force multiplier for your jewelry business, whether you are a beginner or expert, and for small custom shops and factory-scale production alike. With Castable Wax 40 Resin, we aim to reduce the barrier to producing 3D printed jewelry, making production more accessible and efficient.

Advanced Chemistry and Production Grade Reliability

We’ve engineered Castable Wax 40 Resin for jewelers who value casting reliability above all. Castable Wax 40 Resin has been stress tested in the lab and on the casting floor to provide clean castings under a wide range of conditions. Spend less time refining your process and save money on scrapped castings or repairs.

Formlabs has partnered with Rio Grande Jewelry to validate Castable Wax 40 Resin for the most intensive professional use. Casting is complex enough without your resin adding uncertainty. Castable Wax 40 Resin delivers proven reliability for your peace of mind and your bottom line.

Clean Castings for a Wide Range of Jewelry

Jewelry investment molds haven’t changed much for hundreds of years, but the patterns we put in them have. Jewelry investments were made for wax, so it's no surprise many jewelers find that their mold can’t stand up to a relatively taxing resin burnout. Resin casting has its unique challenges: investment compatibility concerns, metal loss from aggressive finishing, and unpredictable casting quality. Many jewelers find themselves asking: resin casting is known for exceptional detail, but what good is detail if it doesn’t cast? 

Castable Wax 40 Resin changes the playbook. Formlabs tailored Castable Wax 40 Resin to play well with fragile investment molds. How? Its resin patterns shrink away from the mold as the wax filler melts, providing oxygen and accelerating combustion while relieving expansion that causes casting defects. 

That means heavy jewelry is now within reach: cast engraved text, stone holes, and channels with confidence using Castable Wax 40 Resin. 

On the other end of the jewelry spectrum, Castable Wax 40 Resin can support the smallest and most intricate features, making it ideal for bridal jewelry.

Exceptional Results Anywhere

We know that each caster’s process is a little different and think that shouldn’t matter. Castable Wax 40 Resin can be used with your standard resin burnout for the majority of jewelry designs. Better yet, Castable Wax 40 Resin works well anywhere in the world—we’ve proven compatibility with investment powders common to the US, Europe, and Asia. 

Castable Wax 40 Resin was also made for jewelry designers. When you ship resin patterns that are compatible with your caster’s production line, your costs go down. Less polishing, less laser welding, fewer rejected designs and test cycles. Castable Wax 40 Resin helps you achieve excellent castings quickly.

Integrate Castable Wax 40 Resin Into the 3D Printing Workflow

Compared to the traditional wax carving workflow, the digital 3D printing workflow can significantly save time. Digital design means endless possibilities for jewelry, enabling designers to efficiently create even the most complex models with high accuracy. Furthermore, it is easy to preserve custom designs, which can be modified or recreated as needed. Producing results similar to injection wax, Castable Wax 40 Resin and 3D printing make a powerful combination.
