Form 3B

More Smiles, All Around

The Form 3B is an advanced desktop 3D printer optimized for biocompatible materials. Our precise, reliable ecosystem takes the guesswork out of dental fabrication so faster workflows are just a few clicks away.

The Easy Choice for Digital Appliance Production

Reclaim your time and produce parts you’ll be proud to deliver, without the hassle or prohibitive costs. Formlabs brings unprecedented reliability, quality, and ease of use, with validated workflows tested by a team of dental experts.

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.
