The best selling professional SLA 3D printer and ecosystem just got better. The newest iterations of our flagship 3D printers, the Form 3+ delivers game changing print speed, surface quality, and reliability. Pair it with the all new Build Platform 2 with patented Quick Release Technology and simplify the post processing workflow so you can get more done with less effort.

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.

Resin Compatibility

  • All resins and resin tanks compatible with the Form 3 are also compatible with the Form 3+. 


Low Force Stereolithography (LFS) 3D printing in the Form 3 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.



The Form 3 constantly monitors print performance so you can focus on bringing your most creative ideas to life. Integrated sensors help maintain ideal print conditions and send you alerts about the state of your machine. 


Switch seamlessly between a library of general purpose and specialty resins. Switch between materials in seconds with a cross-compatible cartridge system. 


Start with one 3D printer or many, and add capacity as demand grows. Get helpful, human service when you need it from a Form 3 expert.



The custom-designed Light Processing Unit (LPU) inside the Form 3 uses a compact system of lenses and mirrors to deliver accurate, repeatable prints. The high-power-density laser is passed through a spatial filter to guarantee a clean laser spot.
