Tough Resin

Durable 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.

Durable

Sturdy prototypes that will deform under pressure where other 3D prints fail.

Responsive

Parts that absorb force; flexing and returning to form.

Rugged

Prints that can tolerate mechanical friction and strain.

Stress-Strain Curve

None

In engineering, toughness is defined as the area under a stress-strain curve. 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.

Note

To achieve desired durability, prints made with Tough Resin should be post-cured approximately 30 minutes at a 45°C temperature under a 405 nm wavelength light source. Read our Material team's post-cure recommendations.

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. Find out more about using Tough Resin.

Handling & Safety

Our resins have been designed to be as safe as possible, but nevertheless, working with them requires care, similar to working with common adhesives or household cleaners. They do not have volatile solvents so special ventilation is not required, though skin contact should be avoided.
