Form 4B vs. Form 3B/+

Blazing Speed Meets Unmatched Accuracy

Form 4B vs. Form 3B

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."

*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.
