    MonoSteps to Success

      1. Preparation of Resin: Shake the resin container well to ensure uniformity. Carefully remove the protective seal. Pour the resin into the printer’s vat and allow bubbles to dissipate before proceeding.
      2. Calibration Test: Print a calibration model to ensure the printer is dialled accurately for the new resin. This helps fine-tune the settings for optimal printing success.
      3. Model Placement and Support Structure: Given the elastic nature of PRO Rubber-like resin, proper model placement and support structure are vital. Set the supports to be heavy and dense, ensuring strong contact points. Place models directly on the build plate whenever feasible to enhance print success.
      4. Design Considerations for Hollow Parts: For hollow parts or designs prone to creating suction, create 1-2mm holes near the build plate in the model using your slicer software. This allows air to escape during printing and facilitates resin drainage from hollow sections post-printing.
      5. Lift heights and speeds: Since the material is prone to stretching during printing, we recommend increasing the build plate lift heights and reducing your print speeds. This will aid in the printing process and reduce the failure rate considerably.
      6. Post-Printing Cleaning: Start with a pre-wash using ResinAway or Isopropyl Alcohol to remove uncured resin. Follow up with a thorough cleaning in an ultrasonic cleaner or wash unit. Dry the print completely using compressed air or a lint-free cloth. It’s important to avoid water contact until post-curing is complete.
      7. UV Post-Curing: Expose the print to UV light in a curing unit, ideally with a wavelength range of 365-405nm. A 60-minute exposure is recommended, although larger parts may require a longer duration.
      8. Heat Curing for Enhanced Properties: Heat curing is recommended for optimal mechanical properties. This involves curing the part at 70°C for 60 to 120 minutes.
      9. Final Inspection and Finishing: Inspect the print for imperfections or uncured resin after curing. If necessary, perform light sanding or trimming to refine the surface or remove any support marks.
      10. Storage of Unused Resin: If unused resin is in the vat, filter it and store it in an airtight container. Please keep it away from direct sunlight and in a cool, dry place.
      11. Maintenance of Printer and VAT: Regularly clean and maintain your printer and VAT to ensure consistent printing quality. Check for resin spills or debris and clean accordingly with ResinAway Ezy Wipes.

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


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


    Tensile Springback occurs as atoms revert to their equilibrium positions following elastic deformation.

    Always shake resin well before printing. It’s recommended to wait for the surface bubbles to pop before starting your print. PROTIP: A lighter or heat gun can speed up this process.

    The new large format printers can 3D Print massive models but have tend to have low volume vats. Ensure you have enough resin to complete the print job, and remember to top up the resin vat if necessary.

    When stored correctly, Monocure 3D resins can last up to 36 months. Remember to keep your resin in its original bottle, in a dark, cool place away from direct sunlight. Do not allow the materials to freeze.

    For the best result with Crystal Clear, always post-cure using 405nm UV light for a short time only. Polishing or using a clear gloss acrylic spray paint, will give you see-through results.

    All Monocure 3D PRO resins are versatile and can be printed between 10 and 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.

    Check our printer setting page to see if we have your printer listed to give you a good starting point. (Not all slicers have this setting, check with your software provider). Use a calibration model to dial in your printer with our resin.

    Wash Up



    For best results after printing, use ResinAway® to remove 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.

    1. 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.
    2. PRO™ resin 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.
    3. 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.
