Perfectionism That Scales
With advanced Low Force Stereolithography (LFS)™ technology, Formlabs has completely re-engineered resin-based 3D printing to drastically reduce the forces of the print process.

Layer Thickness
Low Force Stereolithography (LFS)™ uses a flexible tank and linear illumination to deliver groundbreaking print quality and printer reliability.
Twice the Laser Power
Two staggered Light Processing Units (LPUs) inside the printer use a compact system of lenses and mirrors to deliver accurate, repeatable prints.

Laser Power
Faster printing:
The two LPUs work simultaneously along an optimized print path to efficiently blaze through parts of all sizes.
Crisp, clean features:
Each high-density laser passes through a spatial filter to guarantee a clean laser spot.
Consistent precision:
A parabolic mirror ensures that the laser prints perpendicular to the build plane, ensuring uniform print quality across the entire build platform.
Nonstop Printing
Integrated sensors help maintain ideal print conditions and send you alerts about the state of your machine.
The Form 3L can hold two easy-to-switch resin cartridges, preventing interruptions during large print jobs.
Closed-loop calibration:
Optical sensors continuously correct for scale and power, and can even detect dust.
User-replaceable components:
The Light Processing Units, resin tank, rollers, and optics window can be replaced in-house, reducing the need for replacement printer shipments.

Design
Design your model in standard CAD software and import an STL or OBJ file into our PreForm print preparation software.

Send prints over WiFi, reprint previous jobs, and manage your print queue with ease with the printer’s intuitive touchscreen interface.

Post-Process
