The Next Generation of Dental 3D Printing

XY Resolution: 
25 microns

Advanced Low Force Stereolithography (LFS)™ technology uses a flexible resin tank and a custom-designed, user-replaceable Light Processing Unit (LPU) to produce consistent, accurate prints. Reduced peel forces lead to incredible surface finish and part clarity, right off the printer.

Built for Production

Build Volume: 
14.5 × 14.5 × 18.5 cm
5.7 × 5.7 × 7.3 in

Print 2-3 times more parts in a single build compared to small build plate DLP printers to spend less time handling your printer and more time on high-value tasks. Production environments can see 55% less labor time and costs compared to DLP. A modular ecosystem allows for unmatched consistency, scalability, and redundancy.

Dental Demands More

Each of our ever-expanding variety of indications is extensively validated and tested to ensure quality and accuracy. Switch seamlessly between a library of Dental Resins with a no-hassle cartridge system.

The work flow


Collect digital images of the patient's anatomy using an intraoral scanner. Send scans along with a digital prescription to the lab or design station.


Import the scans into the CAD software, where the digital design is performed.


Import the CAD file into the PreForm print preparation software to set up printing and easily send it to a Formlabs printer.


Perform cleaning, drying and post-curing of printed parts. These parts are ready to be used in the mouth or for a variety of applications.

A perfect finish

Form Wash and Form Cure streamline the post-processing process to help you produce high-quality parts, every print, faster and easier.

Recommendation to our customers:

We recommend that our customers add the following options to their order:

  1. A Dental Service Plan with a minimum of 2 years warranty. In this way, your business benefits from first-class, worry-free support to ensure continuous production.
  2. Form Wash and Form Cure to automate cleaning and photopolymerize prints (essential process)
  3. Isopropyl alcohol to clean their 3D prints right after printing. A minimum of 8L is required to fill the Form Wash or the Manual Finishing Kit.
  4. To have a spare resin tank when it is worn out. It takes +/- 10 to 20L of use before it is replaced. It depends on the type of resin.
  5. Always have a spare Dental Model resin with you in case supplies run out during printing.
  6. To come and train personally in our showroom to prevent improper handling. While remote training is offered with the DSP, nothing beats in-person training.
