“We have found that we can eliminate appointments for patients because we can produce models so quickly on our Form 4B.”
Dr. Lisa Alvetro,
DDS, Orthodontist at Alvetro Orthodontics
“Form 4B is truly a game changer for our entire production, because now we can produce parts two to five times faster than before. The surface, the small details, the edges, the fit—everything feels more precise. Overall, the printer's speed, efficient movements, added sensors and camera, and larger build platform are fantastic. With Formlabs’ ecosystem, our 3D print success rate is now close to 100%."
Stephan Kreimer,
MDT, Kreimer Dentallabor
“Form 4B is a no-brainer, especially if you're looking at trying to implement a high-quality 3D printer in your practice for the first time. It's definitely an affordable printer and it's going to save you money in the long run versus a traditional analog process.”
Dr. Christopher Baer,
DMD, Baer Dental
“The validated Formlabs ecosystem makes 3D printing scalability easier in our lab. All our technicians, even those with no prior experience with similar technologies, have successfully adopted its use, efficiently integrating digital technology.”
Alan Alves,
Director, Smileep
“What is absolutely amazing with Form 4B is the accuracy of the printing. Because the perception is that the prints are near to zero deviation, zero error between the CAD file and the 3D print. And I can assure you that it is not a common experience with other printers. The fit with the sleeves, it's absolutely amazing.”
Dr. Antonino Cacioppo,
DDS, PhD, Prosthodontist
“The team and I have been blown away by the Precision Model Resin and the speed at which it prints. My metal department has to screw implant screws into models we make and the threads often do not hold. This issue is non-existent in the new model material. If I had two to three Form 4Bs, I could double our production”
Shawn Simpson,
CAD/CAM Technician, Hybridge Implants
