Soft Splint Resin

Soft Splint Resin is a transparent, biocompatible material for 3D printing night guards and occlusal splints. Its lower hardness and high elongation give the cured appliance a softer, more resilient feel than rigid splint materials, while impact and abrasion resistance support everyday use.

Comfort and Resilience for Night Guards and Occlusal Splints 

A soft splint needs enough flexibility for comfortable wear without becoming too weak for everyday use. Soft Splint Resin combines high elongation with impact and abrasion resistance for appliances that can flex while maintaining their shape during normal handling and wear.


  • Flexible, Not Brittle With an elongation at break of ≥150%, the cured material can tolerate greater deformation before breaking, helping reduce brittle behavior during handling and use.
  • Built for Daily Wear Impact and abrasion resistance help the printed appliance withstand repeated insertion, removal, biting, and routine use.
  • Clear Finish The transparent material keeps the appliance visually unobtrusive and makes the splint easier to inspect during finishing and fitting.

Minor Fit Adjustment After Printing

Small fit corrections can be made after printing by warming the splint in hot water. This allows technicians to refine the shape or seating when needed without remaking the appliance.

The material is intended for minor fit adjustment rather than major reshaping.

What 3D printers are compatible with Soft Splint Resin?

Soft Splint Resin works with compatible LCD 3D printers using a 385–405 nm light source. Share your printer model with us if you need to confirm compatibility or available printing settings.

Can I adjust the fit after printing?

Yes. Hot water can be used for small adjustments to the shape and fit of the printed splint. It is intended for minor refinement rather than major reshaping.

Is Soft Splint Resin biocompatible?

Yes. Soft Splint Resin is a biocompatible material developed for dental night guard and occlusal splint applications.

How is Soft Splint Resin different from Hard Splint Resin?

Soft Splint Resin has lower hardness and higher elongation, giving the finished appliance a softer and more resilient feel. Hard Splint Resin is used when greater rigidity and stiffness are preferred.

What is Soft Splint Resin used for?

Soft Splint Resin is used to 3D print night guards and occlusal splints that require a softer, more resilient material than a rigid splint resin.
