 The FLEX100™ has an extremely high level of flexibility so you can 3D print compressible and bendable models.


The FLEX100™ has an extremely high level of flexibility so you can 3D print compressible and bendable models.

The thinner the part, the more flexible it will be. FLEX100™ can be used on its own or by mixing with our other resin systems to produce varying degrees of flexibility and firmness. By adding a small amount of FLEX100™ to our other resins would create a less brittle and more durable part. By adding larger amounts, the more flexible it will become.

Remember to use scales to weigh the resins so results can be repeated. We recommend you make 100grams at a time to keep the ratios simple. For example, for a firm, durable resin try 25:75 mix – 25 grams of FLEX100™ to 75 grams of hard resin. For a very flexible version, you could try 90:10 mix 90 grams of FLEX100™ and 10 grams of hard resin.

IMPORTANT: When mixing FLEX100™ with our other resin systems, please ensure that you cure for a long enough time to fully cure the flexible resin. This is a slower curing resin and takes more UV exposure to fully cure. Although the part might look perfectly formed, if it hasn’t been cured for long enough, cracks may appear due to the resin being under cured.

All Monocure 3D resins have a very wide range of reactivity, UV wavelengths of 225nm to wavelengths of 420nm. By incorporating a blend of photo-initiators, monomers & sensitizers, almost any UV light source can be used to initiate the polymerisation process of our resins.

Truly Flexible
A 3D Printing resin that is fully flexible when printed. Perfect for Prototype models that require these properties.

High Impact
Adding as little as 10% FLEX100™ into your hard resin can allow it to be dropped without breaking.

Ultimate Additive
FLEX100™ can be used to mix with hard resins to give you different degrees of hardness and flexibility.

Low Viscosity
This formulation is on 30cps (water is 0cps), it can also be used to help thin down resins when a better flow is required due to colder climates.


  • Use thick, dense supports when creating models using only Flex100.
  • Lower the layer height to 25um get a better result.
  • Use our CMYK pigments if you would like to create your own custom colours.
  • If using as an additive, remember to use scales to weigh the resins so results can be repeated.


  • 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.
  • FLEX100™ requires post-curing to reach its optimal 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 durability of the resin.
