Form 4B vs. Form 3B/+
Blazing Speed Meets Unmatched Accuracy
Discover how you can improve your productivity, print quality, and workflow, as well as reduce costs and lead time by upgrading to Form 4B from Form 3B or Form 3B+.
Improvement
form 4 vs. form 3
2-5x Faster Print Speed
Speed improvements enable same-visit appliance delivery or more efficient production.
“I can print models in six minutes. That means this is approaching the point where models can be printed almost as fast as we can scan a patient."
Dr. Christopher Baer, DMD, Baer Dental

*Due to the larger print surface of Form 4B, more parts can be printed in one print job.
20% Larger Print Surface and 30% Larger Build Volume
Unrivaled Accuracy
Matches your commitment to a perfect fit, every time.
“Consistent print quality with great surface accuracy makes this printer an excellent choice for dentistry. The surface comparison yielded some of the best results I have ever measured on a 3D printer.”

Two New Dental Resins
Faster print speed, increased accuracy, finer features, and improved aesthetics at a lower cost.
15+ materials for dental applications, including biocompatible resins.
“We have a printer that is super fast, it has great resin options for every single indication in dentistry, and it comes at an affordable cost.”
Dr. Ahmad Al-Hassiny DMD, Institute of Digital Dentistry, IDD
Faster ROI
Substantially lower operating costs thanks to cost-effective materials and long-lasting consumables.
If you handle 20 aligner treatment cases per month (20 models per case), you'll save $3000 per year.
Improved Tank Lifetime
Minimize upkeep costs and waste with long-lasting consumables.
Upgraded Cartridge
Our next-generation resin cartridge enables hassle-free, efficient, and fast automatic resin dispensing.
Integrated Camera
Access images and timelapses online to remotely monitor your prints.

Form 4B Delivers 99% Print Success Rate
Form 4B achieved stellar results in a series of comprehensive performance tests conducted by an independent third-party lab to evaluate the success rate and repeatability of parts produced on different SLA 3D printers.
“We get all the things we love about Formlabs — and we get that competitive speed. If I had two to three Form 4Bs, I could double our production.”
