Formlabs Form 4BL Formlabs newest large-format printer, the Form 4BL, delivers industry-leading reliability, accuracy, and exceptional surface finish for biocompatible medical devices. Print large parts in under 6 hours decreasing product development times or mass produce hundreds of devices on one build platform eliminating costly injection molding and accelerating your time to market. Built for commercial-scale production, the Form 4BL is backed by Formlabs’ trusted regulatory support—ISO 13485, FDA Master Files, and more. The future of medical 3D printing is here, and it’s faster, bigger, and more reliable than ever. As of Feb 1st, 2026, all Form 4BL's will come with an Open Material License so you can use 3rd party resins without reservation.

It produces high-performance parts with amazingly fast print times and makes it possible for our model makers to produce multiple iterations in a 24-hour period. - Mark Honschke, Additive Prototyping Lead -Microsoft "The dramatic increase in print speed for Form 4 has significantly accelerated our fabrication cycle - to the point where I can iterate through many different designs every day and go from design to usable functional parts within the hour" -Matt Mullin, Laser Engineer -NASA "I really appreciate the reliability paired with the speed. it's not one or the other, like many other tools. Now I can commit to internal deadlines and feel confident that I can deliver every time.
