SprintRay Inc., a leader in digital dentistry and 3D printing solutions, announced the commercial release of OnX Tough resin, a next generation hybrid ceramic resin designed for 3D printing dental prosthetics. This new resin, which uses SprintRay’s proprietary NanoFusion™ technology, provides unparalleled durability and lifelike translucency for high-quality, same-day smiles.
“SprintRay was founded on the promise of building carefully-curated 3D printing solutions to enable dental providers to deliver an exceptional patient experience. This breakthrough OnX Tough material represents a paradigm shift for chairside dentistry, delivering customized, beautiful and functional dental prosthetics while the patient is in the chair.”
– Amir Mansouri, Ph.D., CEO and Co-Founder, SprintRay
OnX Tough Resin with NanoFusion™ technology

Dental prosthetics are in high demand, with the global market expected to reach $9.71 billion by 2026. Approximately 178 million adults in the United States alone are missing at least one tooth, and 40 million are edentulous (missing all teeth). Traditionally, dental prosthetics are manufactured by sending digital or analogue impressions to a lab, with turnaround times averaging 3-4 weeks for some patients. First generation 3D printing technologies enabled in-office manufacturing of dental prosthetics with the advent of digital dentistry and 3D printing, but with significant limitations.
“When creating OnX Tough, we set out to design a next generation resin that addressed a key limitation of 3D printed prosthetics today – durability and toughness. To address these limitations we developed NanoFusion™ technology, a new approach to dental chemistry.
– Sumeet Jain, Ph.D., Vice President, Materials, SprintRay
Jain continued, “NanoFusion™ materials have a novel composition and form dense polymer chains to deliver dental prostheses with best-in-class fracture toughness, 5X that of first generation technology. Furthermore, the composition brings a perfect combination of translucency and opacity to mimic that of natural dentition.”
OnX Tough is fully integrated into the SprintRay 3D printing workflow and joins an expanding portfolio of digital solutions, which includes:
- The Fastest Dental 3D Printing Ecosystem: With Pro55 S and Pro95 S printers equipped with Bolt speed, most dental appliances can be delivered in less than 60 minutes.
- Smart Print AI: By leveraging the power of artificial intelligence, Smart Print AI automates and hands-free 3D printing with SprintRay.
- Growing Resin Portfolio: Over 15 proprietary, biocompatible, and model materials have been developed and tested for market-leading performance in digital dentistry.
