Monocure 3D TUFF™ resin is a unique blend of advanced urethanes specifically designed to produce a part that possesses high tensile strength. These mechanical properties provide a right balance of strength, flexibility and a hard surface finish. Use M3D TUFF™ if you intend to 3D print robust engineering prototypes; it was designed to withstand high stress and strain. Once fully post-cured, TUFF™ can also be machined, painted or polished for further finishing.

TUFF™ requires post-curing to reach its optimal mechanical properties. We recommend using a 405nm LED Ultra-Violet light to post-cure the model. It is recommended to post-cure for at least 30mins to improve the tensile strength of the resin, but up to 2 hours will further enhance the mechanical properties.
