Formlabs Form 3B+ — Technical data

The Form 3B+ is the revised dental version of the Form 3B and is aimed at labs, practices and clinics. Like the Form 3+, it uses Low Force Stereolithography with a Light Processing Unit (250 mW, 405 nm, 85 µm spot); Formlabs specifies a build volume of 14.5 × 14.5 × 19.3 cm and layer thicknesses from 25 to 300 µm. It is released for 45 Formlabs resins, 18 of them biocompatible, plus third-party resins in Open Material Mode. The printer weighs 17.5 kg and draws 220 W. It was replaced by the Form 4B with LCD-based exposure.

When buying, how the 3B+ was operated matters. Formlabs rates a resin tank at 250 to 800 printing hours or 10 to 35 weeks of resin exposure – so included tanks are often worn out. Check the error log and the LPU, ask about the transfer from Fleet Control or Dashboard, a running service plan and whether tanks were kept separate by resin. For everyday dental work, a package with Form Wash, Form Cure and Build Platform 2 is more practical.

Buy or have it printed? For small or changing quantities, having parts printed is often cheaper than your own machine. If you regularly fill many build jobs, your own machine pays off.
