Sprint Ray is an American technology company that designs and manufactures 3D printing systems,[1] materials, and software used primarily in dental applications.[2][3] The company is headquartered in Los Angeles, California.[4]
History
Sprint Ray was established in Los Angeles in 2014 by Amir Mansouri, Jasper Jing Zhang, and Hossein Bassir, who were affiliated with the University of Southern California (USC). Mansouri and Zhang completed doctoral research in manufacturing and additive manufacturing at USC’s Viterbi School of Engineering, where they collaborated in the Advanced Fabrication Lab to develop an early prototype of a desktop 3D printer.[5]
In 2016, the founders launched a Kickstarter campaign for a desktop 3D printer named MoonRay, which raised approximately US$500,000. The initial product was intended for general design and prototyping applications but was later pivoted toward dental applications.[6] In 2019, Sprint Ray released the Sprint Ray Pro, a 3D printer developed for dental clinics and laboratories.[7][8][9][10][11] In 2022, SprintRay completed a Series D funding round led by SoftBank Vision Fund. In September 2025, Sprint Ray announced the acquisition of the EnvisionTEC/ETEC portfolio of dental products, previously part of Desktop Health.[12][13]
Products and technology
Ceramic Crown is a resin-based composite used in Sprint Ray’s 3D printing workflow for permanent dental restorations. The material contains a blend of silica and ytterbium oxide fillers, with particle sizes ranging from approximately one to several micrometers. Studies have reported that filler distribution can change during storage or printing, occasionally forming clusters within the resin. Laboratory tests indicated that Ceramic Crown has a lower elastic modulus than common CAD/CAM ceramic blocks, and surface roughness increased after simulated aging. Microscopy of polished samples revealed small voids and fractured filler particles, which may influence wear and long-term stability.[14][15]
Partnerships and operations
Sprint Ray has maintained affiliations with the Daniel J. Epstein Department of Industrial and Systems Engineering at USC, where members of the company’s leadership team have participated in lecturing and collaborative research.[5] The company has collaborated with dental technology organizations, such as BEGO Group, on material and workflow development for 3D printing in dentistry. In 2025, Sprint Ray entered a five-year partnership with Usain Bolt focused on digital dentistry projects.[16][17]
Awards and recognition
Sprint Ray has appeared on industry rankings and lists, including Fast Company's annual list of medical device companies,[18] the Ernst & Young Entrepreneur of the Year award for the Greater Los Angeles region awarded to its co-founders in 2025,[5] and the Inc. 5000 list in 2023 and 2024.[19][19]
