Tough Resin

Our Functional Resin for Engineering Applications

Tough is durable, adaptive, and impact-resistant. Perfect for engineering challenges, this sturdy, ABS-like material has been developed to withstand high stress or strain. It’s ideal for snap-fit joints and other rugged prototypes.

Stress-Strain Curve

In engineering, toughness is defined as the area under a stress-strain curve. The graph above illustrates how Tough Resin compares to our Standard resins. As illustrated in the graph, Standard resins are quite strong, but will snap under too much force. Tough Resin, however, balances strength and ductility (elongation). Under enough stress, parts printed in Tough will absorb energy and begin to deform before they snap or shatter. This characteristic allows these parts to be more durable and impact resistant than traditional 3D printed parts.


To achieve desired durability, prints made with Tough Resin should be post-cured approximately 2 hours under a 30W, fluorescent lamp emitting in the UVA.

Tough Resin has a low Tg (glass transition temperature) and low heat deflection temperature. This means that thin parts under constant load may deform over time. Tough Resin is not intended for applications at elevated temperatures.
