Monocure 3D RAPID TUFF™ - 500 ml - Clear

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 (see below for more details).

Our development team have created this unique material to remain rigid and hard, yet withstand high tensile pressure. The strength improves with the increased thickness of the printed part. For more delicate, thinner models, it is recommended to add FLEX100™ to increase the flexibility if required.

To test the durability of a material when it is dropped or hit with a sudden force is done by performing an Impact Strength Test. It is essential to understand that this is very different from a Tensile Strength Test.

In an impact resistance test, the material is subjected to a force suddenly without any warning. When measuring the Tensile strength of a material, the pressure is applied to it gradually. Failure for both phenomena happens through entirely different mechanisms. In tensile testing, stress exceeds fracture/ultimate value, and in impact testing, the energy transferred is too much for the material to handle.

If you require a high impact resistant parts, you can mix our TUFF™ resin with our FLEX100™ resin to increase the impact resistance properties as needed. We will be launching premixed TUFF/FLEX100™ resin in our PRO range which is coming soon.

M3D TUFF™ resin is very versatile and can be between 10 micron and 100 micron layer heights. 3D models should always be designed solid without any hollowing. Always print large flat areas on an angle to help with print deformation due to the adhesion to the FEP film. To help with unsupported areas, ensure you use well-positioned, solid supports. We recommend you add 1-2 seconds’ wait after print’ setting to allow the material to cool after curing before starting to lift the build plate. (Not all slicers have this setting, check with your software provider) This resin will print faster than our rapid model resin, please adjust your settings accordingly. Use a calibration model like this one, to dial in your printer with our resin. Check our printer setting page to see if we have your printer listed to give you a good starting point.
