Low Force Stereolithography (LFS)

An Introduction to Low Force Stereolithography (LFS)

LFS 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.

Inside the Form 3L are 2 completely redesigned optics engines, the Light Processing Unit (LPU), which contains a system of lenses and mirrors to deliver accurate, repeatable prints. Within the LPU, a galvanometer positions the high-density laser beam in the Y direction passes it through a spatial filter, and directs it to a fold mirror and parabolic mirror to consistently deliver the beam perpendicular to the build plane.

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.

Nonstop printing

  • Integrated sensors monitor and maintain ideal conditions for consistent performance over time.
  • Switch between materials in seconds with a simple cartridge system.
  • User-replaceable components and foolproof design maximize uptime.

Grows with your business

  • Meet demand, now and forever. Easily transition from one to many with systems that scale.
  • Don’t wait. Print from anywhere as soon as you have files with Remote Print.
  • Works well with teams. Monitor and manage prints and teams with PreForm and Dashboard. Track individual usage and adjust the print queue when you need to prioritize.
