SprintRay
Los Angeles-based dental 3D printing company offering printers, resins, and software for clinical dentistry
SprintRay – WikipediaSprintRay Inc. is an American dental technology company headquartered in Los Angeles, California, founded in 2014 by Amir Mansouri, Jasper Jing Zhang, and Hossein Bassir following research at the USC Viterbi School of Engineering. The company operates in the dental additive manufacturing sector, developing 3D printing hardware, post-processing devices, proprietary resins, and slicing software tailored for clinical and laboratory dentistry.
The company's flagship Pro 2 printer uses patent-pending 35 μm Optical Panel technology and a 385 nm light engine, supporting 15+ dental indications including crowns and bridges, surgical guides, clear aligners, night guards, dental models, and hybrid dentures. Its product ecosystem also includes RayWare Cloud, RayWare Desktop, the Pro Wash/Dry post-processing unit, and ProCure 2 curing device. Notable industry partnerships include a collaboration with Nobel Biocare for implant dentistry workflows.
SprintRay completed a $100 million Series D funding round in 2022, led by SoftBank Vision Fund, with additional investors including Acceleration International, Being Capital, CDBI Partners, and Marathon Venture Partners. The company's estimated annual revenue is in the $50–100 million range, and it employs approximately 339 people as of early 2026.
As a fast-growing player at the intersection of digital dentistry and additive manufacturing, SprintRay is directly relevant to innovations in dental 3D printing materials, post-processing automation, and cloud-based dental workflows. The company actively participates in major dental industry events such as the Chicago Midwinter Meeting and AEEDC Dubai.
Ideas that could help SprintRay
- Water-Compensated Direct-Print Aligner Geometry Engine
A CAD module for dental 3D-print workflows that automatically increases local aligner thickness to offset the stiffness loss caused by water absorption, so direct-printed aligners maintain target forces throughout the entire wear period.
Why it helps: SprintRay's end-to-end print workflow (printer + resin + software) is a natural home for this feature; it would allow them to promise clinically validated force delivery—a strong competitive differentiator over thermoformed competitors.
- Aligner Force-Decay Predictor
A software module that uses quantified water-absorption degradation curves to predict the actual orthodontic force a printed or thermoformed aligner delivers across its full wear period, so clinicians can plan staging correctly.
Why it helps: SprintRay sells direct-print dental resins and printers; a validated force predictor calibrated to their materials would reduce clinician hesitation and accelerate adoption of their aligner resins.
