Form 3L

Powered by Formlabs’ advanced Low Force Stereolithography (LFS)™ technology, the Form 3L provides larger parts at lower cost and faster than ever before.

Small details, big results.

Form 3L is an affordable large format 3D printer designed for professionals for fast turnaround of industrial-quality parts, printed using an advanced Low Force Stereolithography (LFS) process.

Faster printing.

Blaze through large parts with two custom-designed Light Processing Units (LPUs). Two lasers simultaneously build large, dense parts fast.

Powerful, reliable print process.

Form 3L is built around the same powerful LFS process as the Form 3, for the same professional quality, ease of use, reliability, and versatility you’ve come to expect from Formlabs.

Cross-compatibility and uptime.

Use two of the same resin cartridges that are used by Form 2 and 3 to go longer without running out of resin. Use the same user-replaceable Light Processing Unit (LPU) as the Form 3.

Low Force Stereolithography gives you flawless prints, every time.


LFS (Low Force Stereolithography) 3D printing balances detail and speed.

The optical system maintains a precise, dense laser spot to ensure accurate, repeatable prints.

Easy clean-up and smoother parts with tear-away light-touch supports.
