My resin of Choice

Finally having gotten around to using the TUFF resin on my Mono 4, I can say that the quality of prints exceed what I had been churning out previously. As my parts are mainly model railway items, the need for resisting handling and the odd crash is essential. So the combination of toughness and the retention of detail makes this resin uppermost in my mind when ordering new consumables.

Tuff resin

Nice resin once dialed in with minimal voxel lines on an Anycubic Mono 2K, works excellent on an Anycubic M3 Max. You must keep your print environment at around 28C+ for best results. I print a lot of 3D sculpts so the Tuff resin allows for handling without breaking.


I love the Rapid Tuff resins, I do alot of functional 3D prints that need to be strong and not brittle and this resin does the job. I also enjoys printing toy figurines like from the 80's and 90's to actually be played with and this tuff resin works so well and the prints seem to be more durable then the original toys from back then. Keep up the good work guys.


This resin is probably the best resin I've used. I print alot of functional prints that need to be durable and the prints hold up. I also love printing toy figurines like what you would have got back in the 80's and 90's and this resin allows me to have the be played with as intended and not worry about the toys breaking. Keep up the good work.


its one of the best resins I have used not get many fails and when I do it's the machine not the resin, it's not smelly like same resins. it's good stuff

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.



rapid tuff resin

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.

Tensile Strength (MPa)


The tensile modulus of a solid material is a mechanical property that measures stiffness.


Tensile elongation is the stretching that a material undergoes as it is pulled in tension.

Flexural Stress

Resistance of a material to breaking when bent.

Shore Hardness (D)

Shore D Hardness is a standardised test consisting in measuring the depth of penetration of a specific indenter.


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.

Wash Up



  • 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.
