Ultracur3D® xMOLD

Dissolvable Tooling. Real Injection-Molded Parts.

Ultracur3D® xMOLD is a dissolvable photopolymer resin engineered for Freeform Injection Molding (FIM). It enables the rapid production of 3D-printed molds for real injection-molded parts.

With high dimensional accuracy, low viscosity, and rapid residue-free dissolution, xMOLD helps teams move from CAD to molded parts in hours or days instead of waiting weeks or months for conventional tooling.

Material Details

Material Overview

Ultracur3D® xMOLD brings a faster and more flexible approach to injection molding development. By replacing conventional steel or aluminum tooling with fully dissolvable 3D-printed molds, it can reduce tooling costs by up to 90% while dramatically shortening lead times.

The material is designed for Freeform Injection Molding workflows where speed, design freedom, and simplified mold removal matter most. Because the mold is dissolved away after molding, users can create complex geometries that would be difficult, expensive, or impossible with traditional tooling.

xMOLD is ideal for fast validation, bridge tooling, and rapid iteration of molded thermoplastic parts.

From CAD to Injection-Molded Part

Ultracur3D® xMold supports a streamlined digital tooling workflow from mold design to final molded part. The mold is designed digitally, 3D printed, post-cured, and then used as a dissolvable tool in the injection molding process.

After molding, the tool is dissolved to release the finished thermoplastic part. This workflow accelerates iteration, reduces tooling investment, and opens new possibilities for complex part and mold geometries.
