Getting Started with Printing KeySplint Soft™ Clear for the Carbon© Platform


With 10 million TMJ patients in the USA,[1] and Bruxism impacting 10 to 20% of the population,[2] there are so many patients that could benefit from KeySplint Soft™ Clear. This Revolutionary night guard and splint 3D printing resin is a unique patent-pending technology that combines strength needed to protect teeth with the added flexibility for better patient comfort. The formula is precise, strong (not brittle), biocompatible, color stable, and has a shelf life of 3 years. Here are some tips to get started printing KeySplint Soft™ Clear for the Carbon© Platform:

Dispensing Resin

  • Check the cassette and pour required resin amount into cassette using preferred measuring technique.
    • *Make sure resin is well shaken and at room temperature before use.
  • After printing, reuse, discard or filter and save resin for later use. Make sure to remove parts from platform shortly after printing to prevent deformation.
  • Always check liquid resin for solids between prints.


  • Remove parts from the platform while also removing supports.
  • Place parts in dedicated container of fresh IPA. The solvent should cover ¾ of tallest parts.
  • Insert for 3 minutes in an orbital shaker at 140 RPM and remove parts from washtub.
  • Place parts in second dedicated container of fresh IPA and wash additional 2 min on orbital shaker at 140 RPM.
  • Transfer to paper towel lined tray.
  • Wipe entire intaglio surface of each part with IPA-dipped swab.
  • Air dry for 30 min or use compressed air.
  • If glossy areas remain, repeat swabbing and drying.

Pro Tips for Washing

  • Post treatments recommended immediately following a completed print.
  • Washing should occur no later than 8 hrs after print completion.
  • Wash parts in dedicated container (only for cleaning parts printed in KeySplint Soft Clear for Carbon printers.)


  • Cure in UV post-cure unit immediately after parts have dried.
  • Parts are safe for handling after UV curing.
  • Check part for tackiness with a clean glove after curing cycle is complete.
  • Move part to contamination free zone.
  • After curing, polish/finish as needed.
  • Wash with soap and water before delivery to the patient.
