Ease of Use

Software

Advanced and optimized for dental

Formlabs’ free PreForm Dental software is the golden standard when it comes to ease of use. Intuitive functionalities and presets for key indications such as models, splints, and surgical guides help users set up prints automatically, taking care of the orientation, support generation, and material selection in one click.

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.

Resin Identification

Automated resin identification when a cartridge is inserted

Part Removal

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

Prevents part breakage and potential injuries while removing parts.

Post-Processing

Automated

Our post-processing solutions simplify and automate post-processing so you can consistently produce quality results and maintain a tidy workspace with less time and effort.

Resin Mixing

Automated, with debris detection

Monitoring

Integrated camera for remote monitoring and traceability

Technology

Print Technology

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 aligner models in 9 min

8 splints in 54 min

10 surgical guides in 48 min

10 restorative models in 1h 52 min

On average Form 4B is more than 2x faster than the Asiga Ultra across all indications when comparing print time estimates for equivalent resins and layer thicknesses.

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.

Asiga Ultra

Complete Cost

$18,000

The Asiga Ultra printer starts at $14,990, which includes the printer and a basic Asiga Flash curing chamber. Users have to purchase an additional washing solution and a more expensive and advanced curing unit to cure resins for biocompatible applications; the total cost of the system would exceed $18,000.

Cost of Ownership

Resin Tanks

$42.5/L

Tank cost: $85

Tank Lifetime
Users are forced to replace the tank after only 2L of printing. This means for every liter of resin printed there is an additional cost of $42.5 for the tank and more than 10x waste generated from resin tanks compared to the Form 4B.

Service

Additional cost

Service is available through resellers, and there’s no hot swap option available.

Ease of Use

Software

Outdated and with fewer features

Asiga’s free Composer software doesn’t have any presets and has a complicated and outdated interface resulting in a frustrating and poor user experience.

Asiga’s Software Composer is quite outdated and feels clunky compared to others.” - Institute of Digital Dentistry

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.

Resin Identification

No system to verify if the correct resin is inside the resin tank before a print

Part Removal

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

Risk of part breakage or injury while removing parts.

Post-Processing

Manual

Asiga’s Flash post-curing chamber is a basic On/Off nail cure unit. Users have to purchase a third-party wash unit and upgrade to a more advanced and expensive curing unit to cure resins for biocompatible applications.

Resin Mixing

Manual mixing is required periodically, no debris detection

Monitoring

No camera

Technology

Print Technology

DLP

Digital Light Processing

DLP is a resin 3D printing process that uses a light projector to cure liquid resin one layer at a time.

Print Speed

8 aligner models in 29 min

6 splints in 2 h 18 min

8 surgical guides in 1 h 30 min

8 restorative models in 2 h 5 min

Print times are based on Asiga Composer print time estimates using the same parts and equivalent resins and layer thicknesses for a fair comparison.

Productivity

Smaller build surface, smaller batches, more manual labor

The Ultra (50) offers 19.2 x 10.8 x 14.7 cm build volume and the Ultra (32) is even smaller at 12.1 x 6.8 x 14.7 cm, allowing you to print fewer parts in one batch.

Asiga Ultra Vs Formlabs Form 4B BP Size

Supported Dental Applications & Materials

15+ indications

A wide range of indications with hundreds of materials to choose from. Resin validation is done by the resin manufacturer, users have to manually download and upload the settings to the Asiga Composer software.

Open System

Choose from a vast library of third party materials with no additional license required but for the additional cost of $42.5/L due to the requirement of changing a tank after every two liters printed.

Restorative Model Surface Accuracy

Accurate, repeatable prints with a smooth surface finish.

93% of surfaces within 50 μm of CAD model (official Asiga claim). As a reference, and based on Formlabs’ internal testing, the same restorative models printed on the Form 4B yielded a better surface accuracy compared to the Asiga Max UV* (both printed at 50 μm layer thickness). 

Results:

  • Form 4B: 97.4% of surfaces within 50 μm of CAD model
  • Asiga Max UV: 91.3% of surfaces within 50 μm of CAD model

*Results of Asiga Ultra will be published once available.

Wavelength Light

385 nm (365 nm and 405 nm available on request)
