What features do you get? 

  • LFS (Low Force Stereolithography) technology 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. 
  • Improved post-processing: new innovations eliminate the risk of damaging your parts with tools while allowing you to reduce labor and increase throughput. Build Platform 2 and our patented Quick Release Technology releases parts from the print surface instantly. Enhanced light touch support structures detach from the part in seconds. 
  • Two precision Light Processing Units inside the printer achieve consistent accuracy and detail across the entire build platform. 
  • Models printed on the Form 3L have the polished appearance of injection-moulded for realistic prototyping and consumer-ready end-use parts. 
  • Achieve the highest level of 3D printed translucency. With precise layer registration and smooth surface finish, translucent materials print clearer than ever, right off your print bed. 
  • The Light Processing Units, rollers, optics window, and other components can be replaced in-house to ensure 24/7 uptime. 
  • Your Form 3L comes with a 5.5” full color, high resolution, interactive display that keeps track of your prints and printer maintenance so you can keep printing, stress-free. 
  • Remotely monitor and manage your fleet of printers with cloud monitoring.

Greyscale Resins for Prototypes and Models


  • Greyscale Resins (available in black, grey, and white) are ideal for 3D prints that will be painted, sanded, or otherwise post-processed. Opaque with a matte surface finish, and capable of printing the precise detail expected of the Formlabs range, these resins make a great base for your prints.


Greyscale Resin is great for:


  • Painted or post-processed prints

Draft Resin

  • Draft in 3D. Smooth, with neutral grey coloring, Draft Resin is ideal for initial prototypes and rapid iterations and prints up to four times faster than other Formlabs standard materials. Get highly accurate representations of your designs without waiting for full production. Try using 200-micron settings for faster prints or 100-micron settings for models with finer details.


Draft Resin is great for:
