SprintRay

SprintRay is an American dental technology company headquartered in Los Angeles, California. Founded in 2014 by Amir Mansouri, Jasper Jing Zhang, and Hossein Bassir after research connected with the USC Viterbi School of Engineering, the company operates in dental additive manufacturing. Its business is centered on integrating hardware, materials, software, and post-processing into workflows for dental practices and laboratories. SprintRay initially pursued broader 3D-printing and prototyping applications. Its early development was supported by a 2016 Kickstarter campaign that raised $500,000 for the MoonRay printer. The MoonRay was initially presented as a general-purpose prototyping machine, but the company subsequently concentrated its product development on dentistry, where additive manufacturing can be used to produce models, appliances, surgical guides, temporary restorations, and other digitally designed items. The company’s dental portfolio includes resin-based 3D printers, compatible photopolymer materials, washing and curing equipment, and software intended to connect scanning, design, printing, and finishing processes. The SprintRay Pro series, introduced in 2019, became a central part of its dental-printer offering. Its materials portfolio includes products for dental models and other applications, as well as Ceramic Crown, a resin-based composite marketed for permanent restorations. Product claims and clinical suitability depend on the specific material, printer, workflow, jurisdiction, and regulatory authorization. SprintRay has also pursued external validation and partnerships within the dental-materials industry. The company entered into an agreement with BEGO relating to ceramic-filled resins for permanent restorations and announced a material-validation collaboration with Ivoclar Group in 2024. Academic and technical publications have examined the mechanical and surface characteristics of SprintRay-related printed restorative materials. These studies have reported that, after simulated aging, printed resins can differ from milled lithium-disilicate blocks in properties such as elastic modulus and surface roughness, highlighting the importance of material selection and post-processing in restorative applications. The company raised a reported $100 million Series D round in 2022 led by SoftBank Vision Fund. In 2024, SprintRay received patents associated with a magnetic locking mechanism for printing platforms and a multi-stage washing process for printed parts. The company was also involved in a patent dispute with EnvisionTEC, a Desktop Metal subsidiary, concerning layer-separation technology used in Pro-series printers; a preliminary injunction briefly restricted sales of the affected models in Germany in 2021. In September 2025, SprintRay acquired EnvisionTEC’s dental product portfolio from Desktop Health, expanding its position in the dental additive-manufacturing sector and linking a former legal adversary to its portfolio strategy. SprintRay’s positioning is that of an integrated digital-dentistry platform rather than a standalone printer vendor. Its value proposition combines chairside or laboratory production, specialized dental resins, automated post-processing, and workflow software. The company serves dental clinicians, dental laboratories, educators, and other professional users seeking to move selected production steps from subtractive or outsourced manufacturing toward digitally controlled additive processes. In 2025, it was included in Fast Company’s annual recognition of medical-device companies associated with innovation.

SprintRay was established in 2014 by Amir Mansouri, Jasper Jing Zhang, and Hossein Bassir. The founders’ work followed research associated with the USC Viterbi School of Engineering. The company’s early development was not limited to dentistry: its first major product effort, MoonRay, was introduced as a general-purpose 3D printer intended for prototyping and related uses. In 2016, SprintRay raised $500,000 through Kickstarter to support development of MoonRay. Over time, the company shifted its strategic emphasis from general prototyping toward dental additive manufacturing. Dentistry offered a more focused application for resin-based printing, with potential uses in digital models, appliances, guides, temporary restorations, and laboratory production. This transition led SprintRay to develop products and workflows designed around dental scanners, digital design systems, specialized resins, and controlled post-processing. SprintRay introduced its Pro series of dental printers in 2019. The series formed the basis of a broader platform approach in which the printer was combined with dental materials and workflow equipment. Rather than treating 3D printing as an isolated machine purchase, SprintRay increasingly presented printing, washing, curing, and software as connected steps in digital production. The company expanded its materials research and commercial relationships as it moved into more demanding dental applications. Its portfolio came to include model and appliance materials as well as Ceramic Crown, a resin-based composite marketed for permanent restorations. Research in dental journals has evaluated the performance of printed restorative materials and compared their behavior with conventional milled materials. Reported differences, including lower elastic modulus and increased surface roughness after simulated aging relative to traditional lithium-disilicate blocks, illustrate both the potential and the technical constraints of printed dental restorations. SprintRay also entered material-related arrangements with established dental manufacturers. An agreement with BEGO concerned ceramic-filled resins for permanent restorations, while a collaboration announced with Ivoclar in 2024 addressed material validation. These relationships reflected the company’s effort to strengthen the clinical and laboratory credibility of its materials rather than compete solely on printer specifications. In 2021, SprintRay became involved in patent litigation brought by EnvisionTEC, then a Desktop Metal subsidiary. The dispute concerned layer-separation technology used in SprintRay’s Pro-series printers. A preliminary injunction was briefly issued in Germany, restricting sales of the affected models in that market. The litigation formed part of the competitive and intellectual-property context surrounding dental 3D-printing technologies. SprintRay raised a reported $100 million Series D financing round in 2022, led by SoftBank Vision Fund. The financing supported the company’s expansion in dental technology, although the available reference material does not specify the full allocation of funds. In 2024, SprintRay received patents covering a magnetic locking system for printing platforms and a multi-stage washing process for printed parts. These developments reinforced its emphasis on workflow reliability and automation. In September 2025, SprintRay acquired EnvisionTEC’s dental product portfolio from Desktop Health. The transaction broadened SprintRay’s product portfolio and followed the earlier patent dispute between the businesses. By combining its own printer, materials, and workflow products with the acquired dental portfolio, SprintRay strengthened its position in the specialized dental additive-manufacturing market. SprintRay remains an active dental technology company headquartered in Los Angeles. Its business is focused on professional dental users, including clinics and laboratories, and its strategic identity is built around integrated digital production. The company’s current direction combines hardware, resin chemistry, software, post-processing, and commercial partnerships to support the movement of selected dental manufacturing tasks into digitally controlled workflows.
