Print Speed

11 models in 9 minutes

3D print 11 clear aligner models in 9 minutes achieving a throughput of 49 seconds per model thanks to the blazing fast print speed of up to 100 mm/h.

Read this article for a full list of print speed by indication.

Productivity

27% larger build surface, higher productivity

Print up to 11 clear aligner models or 8 splints in one build thanks to the 27% larger 20 x 12.5 x 21 cm build volume.

Supported Dental Applications & Materials

15+ validated indications

A wide range of indications on a single printer, validated, tested, and directly supported by Formlabs.

Restorative Model Surface Accuracy

Accurate, repeatable prints with a smooth surface finish

The 50 μm XY resolution with pre-tuned anti-aliasing for subpixel resolution results in superior fine and sharp feature performance, and helps deliver an unrivaled accuracy of final parts.

On average, Form 4B and Precision Model Resin produce dental models with:

99.7% of surfaces within 100 μm of CAD model**
95% of surfaces within 50 μm of CAD model**
69% of surfaces within 25 μm of CAD model**

^{** Using Precision Model Resin and 50 µm layer height. Tested using a full arch restorative model with dies. Four models were printed per print job on three different printers and post-processed according to the recommended settings.}

Ease of Use

Resin Dispensing

Automatic Resin Handling

No Mess: Automatic resin dispensing eliminates the need for manual intervention, resulting in reliable prints and a clean workspace.
Streamlined Workflow: Resin level sensing and automatic resin dispensing ensure optimal resin levels are maintained with 3x fewer interactions.
Reliable: Consistent, precise, and automated resin dispensing for reliable completion of prints.

Part Removal

Quick, easy, and tool-free with Build Platform Flex

Prevents part breakage and potential injuries while removing parts.

Resin Identification

Automated resin identification when a cartridge is inserted

Post-Processing

Automated

Resin Mixing

Automated, with debris detection

Monitoring

Integrated camera for remote monitoring and traceability

Cost of Ownership

Resin

$79/L

Fast Model Resin for dental models costs $79/L in cartridges, $65/L in 5L containers, and prices can go as low as $35 for bulk orders. Resins for all other applications are also comparable or more cost-effective.

Resin Tanks

$99

Formlabs resin tanks cost 68% less and last at least as long as SprintRay Pro 2’s tanks.

Service

$990

Service and warranty cost 48% less in the first year and 57% less over 3 years, and include superior benefits, such as personalized onboarding, phone and email support, and hot swap expedited replacement in the event your printer needs service.

Light Processing Unit

$535

Formlabs’ LPU lasts more than 5x longer and costs less to replace.

Lifetime details: 600k - 1.9M layers, depending on material and layer height.*

^{*For example, approximately 5,000 prints using diagnostic models (22 mm tall), Grey Resin V5, and 100 µm layer height.}

SprintRay Pro 2 Series

Complete Cost

$17,918

SprintRay Pro 2 printers start at $9,995 for the printer and essentials. With the costly post-processing solutions and service plan, the complete package adds up to nearly $18,000. And this doesn't even include the $1,499 arch kit, which is recommended for certain applications.

Technology

Print Technology

MSLA

Optical Panel™ Technology

A new generation of stereolithography (SLA) 3D printing.

Print Speed

8 models in 13 minutes

Slower print speed and fewer parts per build for each indication due to the smaller build platforms. Theoretical max print speed of 50 mm/h using the standard kit build platform and 100 mm/h using the tiny arch kit build platform (requires an additional purchase).

Productivity

Smaller build surface, smaller batches, more manual labor

The SprintRay Pro 2's 18.8 x 10.5 x 20 cm build volume can only fit 6 full arch dental models or splints, resulting in lower throughput and requiring more printer interactions.

Supported Dental Applications & Materials

15+ indications

A wide range of indications. Some indications require different resin tank and build platform kits.

Closed System

Open material mode unavailable, only third-party materials certified by SprintRay (currently zero materials for the SprintRay Pro 2).

Restorative Model Surface Accuracy

N/A

There is no data on surface accuracy. XY resolution is 35 μm.

Wavelength Light

385 nm

Ease of Use

Resin Dispensing

Manual

Messy and Inconvenient: Manual resin dispensing can be messy, with a higher risk of spills.
Additional Workflow Steps: Requires manual monitoring and adjustment of resin levels, adding time and effort to the printing process.
Inconsistent Reliability: Greater chance of human error with manual resin pouring contributes to frustrating print failures.

Part Removal

Manual one-at-a-time part removal with tools

Risk of part breakage or injury while removing parts.

Resin Identification

Manual, requires an additional step for the user: scanning the bottle before printing

Post-Processing

Automated

Resin Mixing

Manual mixing is required periodically, no debris detection

Monitoring

No camera

Cost of Ownership

Resin

$149/kg

SprintRay's Dental Model resin costs $149/kg (around 0.8-0.9L), with no discount available for higher volumes.

Resin Tanks

$309

Expensive resin tanks.

Service

$1,925

Very expensive service plan with fewer benefits and a tiering structure for repair charges.

Light Processing Unit

$695

Rated for one to two years of printing.
