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 (LFS) printing uses linear illumination and a flexible tank to turn liquid resin into flawless prints. This advanced form of stereolithography drastically reduces peel forces to provide groundbreaking print quality and printer reliability. 


The Form 3L constantly monitors print performance so you can focus on bringing your most creative ideas to life. Integrated sensors hep maintain ideal print conditions and send you alerts about the state of your machine. 


Switch seamlessly between a library of general purpose and specialty resins. Switch between materials in seconds with a cross-compatible cartridge system. 


Start with one 3D printer or many, and add capacity as demand grows. Get helpful, human service when you need it from a Formlabs expert.


The custom-designed Light Processing Unit (LPU) inside the printer uses a compact system of lenses and mirrors to deliver accurate, repeatable prints. The high-power-density laser is passed through a spatial filter to guarantee a clean laser spot.
