SprintRay Inc. is an American dental technology company headquartered in Los Angeles, California.[1] Founded in 2014, it operates in the dental additive manufacturing sector, with a focus on 3D printing systems and materials used in clinical and laboratory dentistry.[2][3]

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 SprintRay 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, SprintRay 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, SprintRay 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][21]

In 2021, SprintRay 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 SprintRay's acquisition of the EnvisionTEC dental portfolio in 2025.[13][14]

Recognition

In 2025, SprintRay was included in Fast Company's annual list of medical device companies identified for innovation.[23]
