SprintRay.

SprintRay's company page says the firm was founded in Los Angeles in 2014 and that what began as a 3D-printing project by two USC engineers became a chairside system of printers, software, materials, and workflows. Amir Mansouri is named co-founder and CEO. A USC Viterbi article says Mansouri and Jing Zhang launched a 2016 Kickstarter for a desktop printer that raised over 400,000 dollars, then pivoted from general printing to dental appliances such as night guards and dentures. A Los Angeles Business Journal account adds industrial designer Hossein Bassir as a third co-founder in late 2014 and says a Glidewell lab order in 2017 helped push the company to focus on dental offices rather than only labs.

The company page describes a connected platform so a clinician can scan, design, manufacture, and deliver in one visit. The USC article says the process builds layers from liquid polymer and UV light and that an appliance can be printed in less than an hour. Those times are the articles' descriptions of the workflow, not a guarantee for every resin and every appliance. The printer, the resin, and the cure unit are separate parts of the system.

The Business Journal said SprintRay opened a 40,000-square-foot Glassell Park facility to assemble printers and train users, and that the company sells printers through distributors rather than printing the appliances itself. A later Business Journal note said an FDA clearance covered printing porcelain crowns, after earlier use that had centered on night guards. Clearance is model- and material-specific. Read the indication, not the brand headline.

Do not treat a Kickstarter-era general printer as the dental unit on a current quote. Ask for the model name, the validated resins, and whether the software subscription is included. Prices that appear in old interviews are omitted here because they go stale. The company page says the ecosystem includes cloud services and clinical workflows so a restoration can be designed and made in one visit. A one-visit claim still depends on the scan, the design approval, the print, and the cure. The USC article says early general-purpose printers also went to industrial buyers before the dental focus. Those customers are not the dental IFU. A night guard, a model, and a crown can require different resins even when they come out of the same printer.

SprintRay suits a practice that wants to print appliances in the office instead of sending every case to a lab. Printers are compared on the dental 3D printer guide.

The printer is only useful with a validated resin and a cure step. Confirm both before you promise same-day delivery to patients.

SprintRay's stated focus, in the Business Journal account, is the dental office rather than the large lab. A lab may still print or mill the cases you do not validate in-house.

An FDA clearance for one crown material does not clear every resin. Keep the clearance letter with the material SKU.

List the printer model, wash and cure accessories if required, the resin kit, software, and training. The 2014 founding and the 2016 Kickstarter are history, not the spec sheet.

Distributor delivery is how the Business Journal said the printers reach offices. Ask who services the serial number after install.
