MSLA
Low Force Display™ (LFD)
A new generation of stereolithography (SLA) 3D printing where reduced peel forces lead to incredible surface finish and unmatched accuracy.
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.
Open System
Open material mode available enabling third-party resins.
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.

Print Speed
N/A
50 mm/h using the standard kit build platform. 100 mm/h using the 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, closed system
A wide range of indications. Some indications require different resin tank and build platform kits. Open material license unavailable.
Restorative Model Surface Accuracy

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
