Low Force Stereolithography (LFS).

Material Innovations Expands Production Applications.

Low Force Stereolithography (LFS).

The first Formlabs Desktop 3D printers offered a much smaller and more affordable setup than existing industrial SLA machines. The inverted SLA process behind the Form 2 reduces footprint and cost, but exerts significant forces on the part during printing. The printer accounts for this with heavy calibration, but heightened peel forces introduce limitations around materials and build volume, and parts require sturdy support structures to print successfully. With the introduction of Low Force Stereolithography (LFS), Formlabs has completely re-engineered our approach to resin-based Desktop 3D printing to drastically reduce the forces exerted on parts during the print process. LFS Desktop 3D printing uses a flexible tank and linear illumination to deliver incredible surface quality and print accuracy. Lower print forces allow for light-touch support structures that tear away with ease. Additionally, this process opens up a wide range of possibilities for future development of advanced, production-ready materials.

Form 3+.


Produce functional, high-quality prototypes and end-use parts in record time with the Form 3+, an affordable, industrial-quality Desktop 3D printer that reliably delivers.


Rapid print speeds: A powerful, high-intensity laser and precisely tuned settings for every material deliver rapid print speeds.

Easy support removal: Enhanced light touch support structures detach from parts in seconds to save post-processing time.

Crisp, Clean, Accurate Features : LFS technology accurately resolves fine features by delivering a clean, uniform laser spot across the entire print surface.

Production-Like Surface Finish: A flexible resin tank and refinements to the Light Processing Unit (LPU) create near perfect alignment between printed layers, giving parts a production-like finish.
