SprintRay Review: Chairside 3D Printing for Practices

SprintRay is a Los Angeles-based dental technology company, founded in 2014, that designs printers, post-processing units, washing systems, materials, and design software specifically for dental practices and labs. If you’re evaluating chairside 3D printing, it’s one of the few vendors offering a genuinely closed-loop ecosystem rather than a collection of loosely compatible parts.

That’s the short answer. The longer one involves real trade-offs, a fast-moving product line, and a few things worth scrutinizing before you sign a purchase order.

What SprintRay Actually Sells

The product line splits into two distinct printing technologies, which matters more than most buyers initially realize.

Digital Print (DLP) — The Pro S and Pro 2 printers use digital light processing and are the established workhorse line for models, surgical guides, night guards, and temporaries. The Pro S adds smart sensors, RFID resin-tank tracking, and a heated printing platform. Per the manufacturer, the Pro 2 (introduced in 2024) is positioned as the next-generation option for practices wanting to span removables through restoratives. For guided implant surgery workflows, the Pro S in particular has seen broad adoption for printing surgical guides chairside.

Digital Press (Midas) — This is the more distinctive product. Launched in 2024, Midas is marketed as the world’s first Digital Restoration Press. It uses what SprintRay calls Digital Press Stereolithography (DPS), which forces highly viscous resins — ones incompatible with conventional resin tanks — through a sealed capsule against a transparent window, polymerized layer by layer with a 385 nm light source. The capsule handles dosing and shade identification automatically. In a single cycle, Midas can produce up to three crowns, six inlays or onlays, or nine veneers, according to SprintRay’s published specifications.

The no-mess, no-training pitch is real in the sense that there’s no resin pouring or stirring. Whether it fully eliminates training overhead in practice is harder to verify from manufacturer materials alone.

Materials: What’s Cleared, What’s Pending

SprintRay’s Ceramic Crown resin is FDA 510(k) Class 2 cleared for definitive full and partial single crowns and veneers, with a formulation the company says is over 50% ceramic by composition. The company reports more than 70,000 restorations printed with Ceramic Crown resin in the US over the past 24 months — a vendor-reported figure worth noting but not independently verified.

OnX Tough 2 is cleared for fixed, implant-supported denture prosthetics and, per SprintRay, allows up to 10 fixed dentures in 30 minutes. Digital Temp, the temporary material, uses proprietary NanoFusion technology and is FDA 510(k) cleared for temporary crowns and bridges.

EU practices should pause here. As of IDS 2025, both Ceramic Crown and OnX Tough 2 are pending Class IIa certification under the EU Medical Device Regulation. They are not yet available for European clinical use. The European office, opened in Weiterstadt, Germany in April 2021, handles distribution and education but can’t yet offer the full restorative material portfolio.

Coming in Q3 2025: Direct Print Retainer Resin for clear retainers. A SportsGuard Resin is also available in Crimson Red and Cobalt Blue for custom athletic mouthguards — a niche product, but one that fits naturally into a practice that already owns a printer for other indications.

The Software Layer

AI Studio is SprintRay’s cloud-based design platform. It connects directly to 3Shape, DEXIS, and Medit scanners — so if you’re already using one of those (see our roundup of the best intraoral scanner options), the import workflow is reasonably direct. The software automates margin detection and restoration anatomy without requiring CAD expertise. That’s a meaningful differentiator for single-doctor practices that don’t have an in-house technician.

The NanoCure post-processing unit uses dual-wavelength LEDs and a touchscreen interface. Per the manufacturer, it can complete the post-processing cycle for printed dental models in approximately two minutes — a vendor-reported figure; real-world processing times will vary by material and geometry.

How the Ecosystem Fits Together

The strongest argument for SprintRay isn’t any single device — it’s that the printer, post-processing unit, wash, materials, and design software are all developed to work together. That cuts integration headaches and gives you a single support relationship. The risk is the same as any closed ecosystem: you’re tied to one vendor’s material pricing, software roadmap, and hardware refresh cycle.

For digital dentures workflows, the OnX Tough 2 clearance is relevant, though labs or practices accustomed to milling may find the print-and-press workflow requires protocol adjustment.

What Changed With the EnvisionTEC Acquisition

SprintRay’s purchase of the EnvisionTEC dental portfolio added more than 200 patents across hardware and materials, including platforms built on continuous digital light manufacturing and Flexcera, a hybrid nano-ceramic resin with both US and EU market clearance. As reported by Dental Tribune, this expands SprintRay’s reach into lab-side applications and gives it an established customer base beyond its core chairside market. It also means the IP picture is broader than the SprintRay brand suggests at first glance.

Who It’s Built For

SprintRay’s chairside focus suits practices that want to produce temporaries, models, surgical guides, and now definitive crowns in-house without routing work to an external lab. The Midas workflow in particular targets practices doing moderate-to-high crown volume where same-day delivery is a competitive differentiator.

It’s less obvious fit for large dental labs that need high-throughput batch production — the EnvisionTEC platforms may serve those users better — or for practices in the EU that need definitive restorative materials today.

If you’re mapping out a digital dentistry workflow from scanner to seat, SprintRay is a coherent option to evaluate. Just confirm materials clearances for your jurisdiction before committing, and run the numbers on per-unit material costs against your current lab fees. That math is what actually determines whether chairside printing pays off.
