Parts printed on the Formlabs Form 3L 3D Printer


Formlabs Form 3L achieves incredible print quality thanks to its trademark technology—Low Force Stereolithography (LFS). By combining a flexible tank with linear illumination, the forces exerted on parts during the printing process are drastically reduced leading to sharp details that are finer than ever, parts snapping cleanly off supports, and reliable print results that are easily repeatable.

  • High-quality, repeatable prints with two custom Light Processing Units (LPU)
  • Smooth surfaces with LPU's linear illumination
  • Clean support removal with reduced peel force


Focus on bringing your innovative ideas to life while the Form 3L monitors its print performance. Ideal print conditions are maintained thanks to its integrated sensors to ensure minimal human supervision for nonstop throughput. Other features for efficient production include:

  • Monitor & manage machines with online Dashboard
  • Balance print speed and details with Draft Resin for fast iteration
  • Achieve 24/7 uptime thanks to many Formlabs components that can be replaced in-house
