Tough Resin balances strength and compliance, making it the ideal choice for prototyping strong, functional parts and assemblies that will undergo brief periods of stress or strain.
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.
