Tough Resin simulates the feel and many of the important mechanical properties of Acrylonitrile Butadiene Styrene (ABS) plastic.
ABS is a very common thermoplastic that provides a good balance of strength and flexibility.
Tough Resin creates strong engineering prototypes and has been developed to withstand high stress and strain. Consider using this material for “works-like” prototypes and assemblies, including designs with snap fit joints and living hinges.
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.
Toughness directly correlates to the amount of energy each material can absorb before failure.
