KeySplint Hard™ is a high-performance, biocompatible photopolymer resin engineered for 3D printing of rigid dental appliances. Designed for DLP/LCD printers operating at 385–405 nm, this resin enables efficient and precise production of nightguards, splints, retainers, bite planes, and more. 

🌟 Why KeySplint Hard Stands Out

• Rigid & Reliable Strength — Offers high flexural strength (≈ 60–65 MPa ISO 20795-2) and flexural modulus (≈ 1510–1600 MPa), ensuring a stable, long-lasting appliance. 

• Abrasion- and Stain-Resistant — Durable against wear and discoloration, ideal for nightguards or splints exposed to daily use. 

• Biocompatible & Certified — Cleared by the U.S. Food and Drug Administration (FDA 510(k)), approved by Health Canada, and CE-marked (Class IIa) for safe intraoral use. 

• Compatible with Many Printers — Works with a wide range of open-source and commercial DLP/LCD 3D printers. 

• Ideal for Multiple Dental Applications — Perfect for nightguards, splints, bite plates, retainers, snoring devices, and post-trauma tooth immobilization appliances. 

✅ Best For

Dental labs and clinics looking to produce rigid, long-lasting dental appliances with:

• High structural integrity

• Excellent wear and abrasion resistance

• Consistent, repeatable 3D printing results

• Certified biocompatibility and safety
