Formlabs Form 4BL Large-Format 3D Printer Bundle
Form 4BL - A new era in medical manufacturing
Formlabs introduces the Form 4BL, a new generation large-format 3D printer designed specifically for medical and dental applications, offering upgraded speed, reliability, and biocompatibility. Treat urgent cases with large medical parts, or print multiple parts in a single print job to accelerate product development and keep production running.
Large-format prints in as little as 6 hours¹ with a build volume 4.6x larger than the Form 4.
The Form 4BL is powered by Formlabs' new Low Force Display™ (LFD) print engine, with a build volume up to 24.2 liters, 4.6 times larger than the Form 4B.
·Form 4BL: 353 × 196 × 350mm (24.2 L)
·Form 4B: 200 x 125 x 210mm (5.2 L)
Equipped with a high-power LED backlight unit and LPU 4L optics module, it quickly and accurately cures resin, providing extremely fast print speeds across the entire build platform for excellent print quality and precision.
