Low Force Display Technology
High Power Backlight Unit
The custom-designed Light Processing Unit 4 (LPU 4) inside the printer precisely masks light from the backlight unit into the shape of a printed layer.
It delivers the highest optical power on the market (13-16 milliwatts /cm²).
Minimal peel forces for maximum precision:
A proprietary, microtextured optical film that provides airflow between the flexible film resin tank and LPU, allowing for prints that rival injection molded parts.
Intelligent Control Systems:
Six onboard control systems precisely measure and maintain the temperature, resin level, print forces, and print status inside your printer.
Materials
Switch seamlessly between a library of general purpose and specialty resins with a cross-compatible cartridge system.
Formlabs material library contains 25+ materials which are divided into following groups:
Standard
Engineering
Dental & Medical
Jewelry
Accessories
Form 4L Resin Tank
Low Force Display (LFD)™ 3D printing uses a flexible yet strong dual-layer film tank for consistent, high-quality prints. Every resin tank includes a reusable lid, making it easy to stack tanks and store resin outside of the machine. With a separate tank for each individual resin color or type, switching materials is as easy as sliding in a new tank.
Resin Tanks are built to last and deliver consistent performance for at least 75,000 layers of printing (typically 1-2 years for the average user).
Form 4L Resin Mixer
The Form 4L Resin Mixer improves material performance by keeping resin homogenous in the tank during the printing process. A Resin Mixer is required anytime you are printing. Resin Mixers typically last for the lifetime of your printer.
For convenience, we recommend having one Resin Mixer for each Resin Tank.
Form 4L Build Platform
Form 4L Build Platform has a durable aluminum surface. A spare Build Platform can speed up your workflow and allow for nonstop printing, whether you’re changing resins or starting a new print while you remove your part.
Build Platform Flex
Form 4 Build Platform Flex with Quick Release Technology allows you to quickly and easily remove parts from the print surface without tools in seconds. Recommended for almost all prints, Build Platform Flex eliminates the risk of damaging your part and streamlines your workflow.
Form 4L Finish Kit
The Form 4L Finish Kit helps keep your workspace clean and organized while putting the finishing touches on your large 3D printed parts.
This large-scale rinse bucket allows you to rinse prints directly on the build platform or after removal.

Software Solution
3D Printing Software – PreForm
PreForm’s automatic algorithms set up your print’s layout, orientation, and supports, so anyone on your team can print successfully without specialized training.
Expert users can manually adjust a variety of parameters, such as support density and size, to fine tune results.
Design your model in standard CAD software, then import the STL or OBJ file into our print preparation software, PreForm. Get your model ready in minutes, upload to your printer, and let it build.
