TUFF™ Resin
Monocure 3D TUFF™ resin is a unique blend of advanced urethanes specifically designed to produce a 3D printed model with increased tensile strength and long-life durability. These properties provide the right balance of fine detail, strength, flexibility and a hard surface finish.

WHY CHOOSE TUFF™ RESIN?
High Tensile Strength
When measuring the Tensile strength of our material, the pressure is applied to it gradually until it gives. TUFF™ resin has a much higher rating than most resins on the market.
Hard Surface Finish
A hard surface rating of Shore D 92, without being brittle, gives TUFF™ its unique properties. When post-cured, the smooth surface finish is perfect for painting if required.
Longevity & Durability
It’s important that your model lasts the test of time, we have done comprehensive aging tests and TUFF™ has passed with flying colours.
The Offical Test Figures
We had an independent lab do this report on our TUFF™ resin, printed at different heights and with varying cure times. You can download the test report here.
WHAT MAKES TUFF™ RESIN SO UNIQUE?
Monocure 3D TUFF™ resin is a unique blend of advanced urethanes. It was specifically developed to produce a 3D printed model with high tensile strength and long-life durability. These properties provide the right balance of fine detail, strength, flexibility and a hard surface finish.
We recommend using TUFF™ resin if you intend to 3D print models that you want to remain rigid and hard yet withstand stress and strain without being brittle. Once post-cured, it can be machined, painted or polished for further finishing.
Our development team has created TUFF™ resin to be low in viscosity (thinner), so it doesn’t require heating like other resins on the market. Thinner materials can reduce the build-up of resin that can get trapped behind supports.
TUFF™ has a low odour formula to suit confined spaces such as home offices, garages and family living spaces.

TUFF™ PRINTING TIPS
Ensure a long post-cure to increase the tensile strength.
Printing at a lower layer height will increase the overall strength.
Print the part solid, not hollow for the strongest results.
Always print models on a 45 degree angle to help the part release from the FEP sheet.
TUFF™ resin is versatile and can be printed between 5 & 100-micron layer heights. To achieve the best results, 3D models should always be designed solid, if hollowing is required, ensure drain holes are included to remove any trapped resin.
Always print large flat areas on an angle to help with print deformation due to the adhesion to the FEP film. To assist with unsupported areas, ensure you use well-positioned, solid supports.
We recommend you add a 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 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.

TUFF™ FINISHING TIPS
- For best results after printing, use ResinAway® for removing uncured resin from the part. Place part in a pre-wash bath filled with ResinAway® and use a soft brush to remove excess resin. Follow by placing the component into an ultrasonic cleaner with ResinAway® for 3-5mins to help remove the resin trapped in the finer detail.
- Ensure parts are dry by using compressed air or patting gently with a lint-free cloth before post-curing – Warning: leaving excess IPA or ResinAway® on parts might result in surface cracking.
- TUFF™ requires post-curing to reach its optimal mechanical properties. We recommend using a 405nm LED Ultraviolet light to post-cure the model. It is recommended to post-cure for a few minutes, then remove the excess ResinAway by washing with fresh water. Then place it back in the curing chamber for at least 30 mins to improve the tensile strength of the resin. (2 hours will further enhance the mechanical properties. These properties will also increase over a few days).
- When exposing a part to external elements, apply paint to the surface to improve longevity. Alternatively, the components can be machined, sanded and polished to create a tough scratch resistant surface.
