Engineering Resins

Specialty photopolymer resins for precision, high-temperature, flexible, and biocompatible applications.

Engineering Resin Properties

Resin Type Property Profile
Standard Grey/White High detail, smooth finish — visual prototypes and display
Engineering (Tough) Impact resistant, ABS-like toughness — functional assemblies
Flexible (Shore A 40–80) Rubber-like flexibility — gaskets, grips, seals
High-Temperature HDT 238°C — oven fixtures, automotive, under-hood
Dental SG Biocompatible, Class I/IIa — dental models, surgical guides
Castable Burns out cleanly — investment casting patterns for jewelry/metal
Transparent Optical clarity — lenses, light pipes, clear enclosures
Ceramic-Filled Stiff and smooth — master patterns, tooling applications
Resin Selection Guide

The right resin for
every application.

Engineering resins extend the capability of photopolymer 3D printing far beyond standard visual prototyping. Specialty formulations now cover dental, medical, high-temperature, flexible, and casting applications — each tuned for specific performance requirements.

ExCom stocks and actively uses 12+ resin formulations. Our engineers match resin to application based on mechanical requirements, post-processing needs, and budget.

Standard vs. EngineeringStandard resins are optimized for appearance. Engineering resins trade some surface quality for mechanical performance.
Post-Cure CriticalAll resins require UV post-curing to achieve specified mechanical properties. We calibrate cure time per resin.
Shelf Life & StorageWe maintain strict resin inventory management to ensure material freshness and property consistency.
Custom PigmentationMost resins can be pigmented to custom colors. Pantone matching available for production orders.
