Scale your dental laboratory or clinical operation with the Formlabs Form 4BL—a large-format, medical-grade 3D printer built specifically for high-volume biocompatible production. Featuring a massive 35.3 x 19.6 x 35.0cm build volume (4.6x larger than the standard Form 4 series), the Form 4BL utilizes Formlabs’ Low Force Display™ (LFD) optical engine to combine rapid print speeds with precise accuracy.
 
Key Features & Dental Applications

Biocompatible & Open Material Ecosystem: Validated for Formlabs' library of biocompatible dental resins while offering an optional Open Material Mode license to print with third-party 405nm photopolymer resins.
Ultra-Precise Surface Quality: Equipped with a 46 micron pixel size, collimated Backlight Unit, and tuned anti-aliasing to deliver tight dimensional tolerances for exact appliance fitment.
Automated Resin Management: Includes dual-cartridge dispensing and support for the Resin Pumping System, eliminating mid-print resin shortages during continuous, full-scale production runs.
