Tough

Product catalog summary

Material Overview: Tough Resin is designed for rugged prototyping, balancing strength and compliance. It is ideal for creating strong, functional parts and assemblies that endure brief stress or strain. The resin is priced at $175 per liter.

Mechanical Properties: The resin exhibits an ultimate tensile strength of 34.7 MPa when green and 55.7 MPa post-cured. The tensile modulus is 1.7 GPa green and 2.7 GPa post-cured. Elongation at break is 42% green and 24% post-cured. Flexural strength at 5% strain is 20.8 MPa green and 60.6 MPa post-cured. The flexural modulus is 0.6 GPa green and 1.6 GPa post-cured. Notched IZOD impact strength is 32.6 J/m green and 38 J/m post-cured.

Thermal Properties: The heat deflection temperature at 1.8 MPa is 32.8°C green and 45.9°C post-cured. At 0.45 MPa, it is 40.4°C green and 48.5°C post-cured. Thermal expansion between 23 – 50°C is 159.7 µm/m/°C green and 119.4 µm/m/°C post-cured.

Solvent Compatibility: The resin shows varying degrees of weight gain when immersed in different solvents for 24 hours. Notable results include 2.8% weight gain in 5% acetic acid, 2.1% in hydrogen peroxide (3%), and 6.6% in diethyl glycol monomethyl ether. Some solvents like acetone caused cracking, and strong acids caused distortion.

Additional Information: Material properties can vary based on part geometry, print orientation, settings, and temperature. Data was obtained from parts printed using Form 2, 100 µm, Tough settings, with and without post-curing.
