Tough Resin is our most durable, adaptive, and impact-resistant material. Similar to ABS, it is ideal for engineering prototypes and has been developed to withstand high stress or strain. This material is perfect when you require great impact resistance for rugged prototyping, and can also be used for snap-fit joints, living hinges and parts that require post-print machining. Tough Resin can be printed at 50 and 100 micron layer heights.
Toughness refers to a material’s ability to absorb energy before fracturing. When a tough material yields, it will undergo some deformation rather than just shattering. In other words, tough materials have a little more “give” than brittle ones.
Toughness is also defined as the area under a stress-strain curve. Tough materials generally have a good balance of strength (the amount of stress a material can withstand) and ductility (the elongation or percentage strain). Because of this, the area under a tough material's stress-strain curve is much larger than that of a very strong material with low elongation. This has a direct correlation to the amount of energy each material can absorb before failure. Formlabs Tough Resin has lower stiffness than the Standard Resins while withstanding more elongation.

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. For best results, alter your model to reinforce or thicken parts. You can use the Design Guide as a reference.
Wash your tough parts as recommended for parts printed with Standard Resins:
The Tough Resin coloration comes from a pigment, not a dye, so tough parts will not color the IPA.
Especially with tough resin, leaving parts in IPA too long may cause the parts to become flexible and weak.
Tough parts require about 2 hours of post-curing under a 30 W, fluorescent lamp emitting in the UVA range (such as a nail spa). You may use a lower wattage curing chamber (eg a sterilizer), but your post-cure time will increase. Time to reach full post-cure may also be longer for larger parts.
Your tough part will not reach its full mechanical properties without a thorough post-cure.
