Tough 1500

Product catalog summary

Overview: Tough 1500 Resin is a resilient material designed for prototyping, offering a balance of stiffness and pliability. It is part of Formlabs' Tough and Durable Resins family, suitable for creating parts that require flexibility and strength similar to polypropylene.

Material Specifications:

Mechanical Properties: The resin exhibits an ultimate tensile strength of 33 MPa (4786 psi) and a tensile modulus of 1.5 GPa (218 ksi) when post-cured. It has an elongation at break of 51%.
Flexural Properties: Post-cured flexural strength is 39 MPa (5656 psi) with a flexural modulus of 1.4 GPa (203 ksi).
Impact Properties: Notched IZOD impact strength is 67 J/m (1.2 ft-lbf/in), while unnotched IZOD is 1387 J/m (26 ft-lbf/in).
Thermal Properties: Heat deflection temperature is 45 °C (113 °F) at 1.8 MPa and 52 °C (126 °F) at 0.45 MPa. Thermal expansion is 97 µm/m/°C (54 µin/in/°F).

Solvent Compatibility: The resin's resistance to various solvents is measured by weight gain over 24 hours. Notable results include:

Acetone: 19.07% weight gain
Isopropyl Alcohol: 3.15% weight gain
Minimal weight gain with Isooctane (0.02%) and light mineral oil (0.05%)

Usage Notes: Material properties can vary based on part geometry, print orientation, settings, and temperature. Data provided is based on parts printed with Form 2 at 100 µm and post-cured at 70°C for 60 minutes.
