Form 4L – Large-Format 3D Printing in Record Time

3D Print Large Parts in Under 6 Hours

The Formlabs Form 4L enables large-format parts and high part volumes in hours instead of days. Powered by Low Force Display™ (LFD) Masked Stereolithography (MSLA), you get precise, repeatable results with an excellent surface finish — ideal for development, prototyping, and low-volume production.

Form 4L: Your Advantages in Industrial 3D Printing

Fast & Reliable

With validated print settings, intelligent process monitoring, and newly developed materials, the Form 4L consistently delivers high-quality, repeatable results — from single parts to production runs.

×
Smooth Surfaces

Lower separation forces, easy-to-remove supports, and 46 µm pixel size with preconfigured anti-aliasing for ultra-fine surface quality and supports that remove cleanly.

×
Crisp Details

A highly collimated light system ensures uniform exposure and subpixel resolution — for razor-sharp edges and maximum precision, even on complex geometries.

More Highlights

Highly Collimated Backlight Unit with 145 LEDs
The Form 4L’s Low Force Display™ (MSLA) uses a powerful Backlight Unit with 145 LEDs and collimating optics to ensure uniform exposure across the entire build platform.
The result: sharp edges, precise subpixel details (46 µm), and consistent part quality — even on large print jobs.

Integrated 5 MP Camera with Remote Monitoring 
An integrated 5-megapixel camera automatically documents every print job (photo & timelapse) and enables remote monitoring over your network or via the cloud.
For regulated environments, the camera can be disabled, covered, or removed.

Automatic Resin Handling & Long-Lasting Tank
Two cartridges and automatic dispensing reduce manual intervention and downtime. The next-generation system is designed for 75,000+ layers, reduces waste by 63%, requires 30% less shelf space, and is compatible with the Resin Pumping System — ideal for high throughput.

7-Inch Touchscreen with an Intuitive Interface
From automatic calibration to status checks, all key functions can be managed centrally via the 7-inch interactive touchscreen or over the network. This makes the Form 4L exceptionally easy to use while supporting consistent, reliable processes.
