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, open system

A wide range of indications on a single printer, validated, tested, and directly supported by Formlabs. Open Material License coming soon to enable printing with 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.

MSLA

Optical Panel™ Technology

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

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

N/A

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

Wavelength Light

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 Tanks

$309
