What is TUFF™ Crystal Clear?
Please welcome the newest member of the Monocure3D PRO Resin Range – meet TUFF™ Crystal Clear. This resin is based on our advanced TUFF™ formulation, giving the same incredible high tensile strength. Still, it boasts non-yellowing properties that allow for a high level of clarity through the printed model.
For the best results, use fresh ResinAway® for cleaning away any excess resin after printing, then post-cure gently using only a 405nm LED UV light source. We recommend using 15watt lights or less for around 5mins to keep the part as clear as possible. If extra strength is required, then you may need to increase your post-cure duration.
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.
Impact and tensile Strength – What is the difference?
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.
Ok, so where are the official strength test facts and figures?

TUFF™ Printing Tips – How do I use this resin?
M3D TUFF™ Crystal Clear 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.
Finishing – What’s the best practice?
For best results after printing, use fresh 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. Allowing water to come in contact with the printed part before it is post cued will make it look frosted.
Post-cure gently using only a 405nm LED UV light source. We recommend using 15watt lights or less for around 10mins to keep the part as clear as possible. If extra strength is required, then you may need to increase your post-cure duration.
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.
