History
The company was founded by Amir Mansouri, Jasper Jing Zhang, and Hossein Bassir, following research conducted at the USC Viterbi School of Engineering.[4]
In 2016, the company raised $500,000 through Kickstarter to fund development of its first 3D printer, the MoonRay. Although initially positioned for general prototyping, subsequent development efforts shifted toward dental applications.[5][6]
In 2019, the company introduced the Sprint Ray Pro series of dental printers.[7][8][9][10][11]
In 2022, it completed a $100 million Series D funding round led by SoftBank Vision Fund. In 2024, Sprint Ray was granted patents related to a magnetic locking system for printing platforms and a multi-stage wash process for post-processing printed parts.[12]
In September 2025, Sprint Ray acquired the dental product portfolio of EnvisionTEC (ETEC) from Desktop Health.[13][14]
Material research and collaborations
The company's primary material for permanent restorations is a resin-based composite marketed as Ceramic Crown.[15][16][17]
Research published in the Journal of Esthetic and Restorative Dentistry and Odontology has evaluated its mechanical performance, noting that printed resins generally exhibit a lower elastic modulus and higher surface roughness after simulated aging than traditional milled lithium disilicate blocks.[18][19]
The company has also entered material validation agreements with dental manufacturers, including a collaboration with Ivoclar Group announced in 2024 and an earlier agreement with BEGO relating to ceramic-filled resins for permanent restorations.[20]
The company also maintains a partnership with Usain Bolt for dental initiatives in Jamaica.[21]
Legal dispute
In 2021, Sprint Ray was involved in a patent infringement suit brought by EnvisionTEC (a subsidiary of Desktop Metal) regarding the layer separation technology in its "Pro" series printers. A preliminary injunction was briefly issued in Germany prohibiting the sale of these models in that jurisdiction.[22]
The dispute was resolved following Sprint Ray's acquisition of the EnvisionTEC dental portfolio in 2025.[13][14]
Recognition
In 2025, co-founders Amir Mansouri and Jasper Jing Zhang were named recipients of the EY Entrepreneur of the Year Award for the Greater Los Angeles region. That same year, Sprint Ray was included in Fast Company's annual list of medical device companies identified for innovation.[23]
