Formlabs Form 4 — Professional Resin 3D-Printer, 4x Faster
Most prints are ready in less than 2 hours — no matter how many parts you put on the platform. Tolerances ±0.15%, injection molding finish, 23 professional resins available from day one.
If you’re still waiting hours for a single resin print, the Formlabs Form 4 is a game-changer. With new Low Force Display™ (LFD) technology, it prints up to 4x faster than the previous generation of Form printers — and it does so without increasing the time as the number of parts on the platform increases, unlike traditional laser systems where more parts means more processing time.
The result is not just speed—it’s injection-molding-like surface quality, with XY dimensional tolerances of ±0.15% that ensure parts are true to your CAD design, print after print. Whether you’re validating a functional prototype, manufacturing assembly equipment, or producing small runs of final parts, the Form 4 is designed to keep up with a real-world pace of work, not a hobby lab.
How Form 4 Speed Works
The Low Force Display™ print engine combines 60 high-power LEDs, collimation lenses, and a liquid crystal display that cure each layer of resin instantly and evenly across the entire platform — not one dot at a time as in laser systems. This means that printing 10 small parts takes the same amount of time as printing 1 large one, which is a real advantage for those working on batches, not just single parts.
Zero compromises on material handling
Next-generation resin cartridges fill up to 10 times faster, reduce material waste by 63% and take up 30% less shelf space. The high-speed, infrared temperature-sensing conduction resin heating system unlocks high-viscosity, high-density materials that were previously simply unprintable — truly expanding what you can produce.
Remote monitoring: control printing from anywhere
The built-in camera transmits print status in real time, with timelapse and history that can be accessed remotely via the Formlabs Dashboard. You don’t need to physically stand next to the machine to know where the job is — a detail that matters when you’re managing multiple prints in parallel or multiple customers in the queue.

Frequently Asked Questions
Is Form 4 faster than Form 3?
Yes, up to 4x faster thanks to the new Low Force Display™ technology, with a 30% larger print volume.
Do I need a dryer to use the Form 4?
No, it works under normal environmental conditions — the dryer is only for specific polyurethane resins.
Can I use third-party resins?
Yes, via Open Material Mode, in addition to the 23 Formlabs resins available since launch.
