Formlabs Form 4B 3D Printer Bundle
Form 4B - A generational leap in medical and dental 3D printing
Formlabs introduces the Form 4B, a new generation machine designed specifically for medical and dental applications, with upgraded speed, reliability, and biocompatibility. With the Form 4B system, turn your medical ideas into reality faster than ever before through a simple workflow, leading reliability, and stunning part quality.
The Form 4B is powered by Formlabs' new Low Force Display™ print engine, a powerful combination of ultra-high power LEDs, collimating lenses, filters, and a robust liquid crystal display. They rapidly cure each layer of resin—regardless of part size or quantity. With tight tolerances, parts printed with every resin on the Form 4B will always match your design parameters.

Form 4B - Product Overview Blazing Fast Printing, Breaking Through Production Limits
Surgical sizing trial - restor3d
The Form 4B prints 4 times faster than its predecessor, with a 30% increase in build volume. Whether printing single parts or batch production, it can be completed in a very short time, significantly improving the work efficiency of medical institutions and laboratories.
Consistent Accuracy
Equipped with 50μm pixel size and pre-tuned anti-aliasing, the Form 4B delivers extremely smooth surfaces and clear details, meeting the highly demanding precision requirements of medical applications such as surgical guides and anatomical models.
Unmatched Reliability
Third-party lab verified, the Form 4B boasts a print success rate of up to 98.7%. With 6 upgraded built-in sensors, it precisely controls resin temperature, level, and print force, ensuring every print is flawless.
