Material
Tough Resin
Tough resin is an impact-modified photopolymer that trades some of standard resin's stiffness for significantly better elongation and impact resistance. This makes it better suited to functional parts that need to withstand stress without cracking.
Manufacturing processes
About
Tough resin is a photopolymer engineered to resist impact and mechanical stress better than standard general-purpose resin.
Standard resin is stiff and detailed but brittle, prone to cracking under sudden force. Tough resin trades away some of that stiffness and tensile strength in exchange for noticeably higher elongation at break, which allows parts to flex somewhat before failing rather than shattering. The exact balance varies meaningfully between manufacturers, as some formulations prioritize a more moderate toughness gain while retaining more rigidity, and others push elongation and impact resistance much further at a greater cost to stiffness.
Tough resin suits functional prototypes, snap-fit enclosures, brackets, clips, and mechanical assemblies that need to survive handling, impact, or repeated use without breaking.
