Sacrificial & Mold-Making 3D Resins

Overview

This collection includes sacrificial mold making 3D resins developed for indirect additive manufacturing workflows using SLA, DLP and LCD technologies. These materials are designed to print sacrificial molds and tooling elements that can be removed after processing, enabling the fabrication of complex components with internal cavities, undercuts and geometries that cannot be produced using conventional mold fabrication methods.

Key features

The sacrificial resins in this collection are engineered to provide precise printing, stable geometries and controlled removal behavior depending on the selected material grade. They support indirect manufacturing by enabling sacrificial molds to be eliminated by thermal processing, solvent-based removal or dissolution-based strategies depending on the process requirements. These materials are designed to maintain sufficient integrity during injection or casting operations while allowing clean release of the final component without damaging critical features.

Typical applications

Sacrificial mold making resins are recommended for indirect manufacturing workflows such as silicone molding, wax casting, polymer injection, composite part fabrication and advanced tooling concepts requiring complex internal geometries. They are suitable for industrial, dental and research environments where sacrificial removal enables the production of intricate parts that cannot be demolded or assembled using standard manufacturing approaches.

Custom resin solutions

If your project requires a specific resin performance profile, tailored viscosity, defined curing wavelength range, enhanced functionality, biocompatibility targets or printer-specific parameter optimization, 3Dresyns can support custom material development and formulation optimization. We provide technical support to adapt resin chemistry and additive packages for specialized applications and advanced printing technologies, including exposure calibration guidance and validation-driven development for high reliability and production-scale workflows.
