The Form 4L is a fast, large-format masked SLA 3D printer. Combines a materials library with a precise print engine for reliable results.
On backorder
A significantly larger build volume compared to the standard Form 4 resin printer.
Large prints are ready in less than 6 hours.
Tackle any challenge with our leading materials or utilise the Open Material Mode.
Anyone can learn to use this resin printer in 15 minutes.
Unmatched success rate when printing large-scale models.
Highly collimated light and a 46 µm pixel size with pre-adjusted anti-aliasing for sub-pixel resolution.
Lower removal forces, lightweight support points, and a 46 µm pixel size with pre-adjusted anti-aliasing.
±0.15% XY dimensional tolerances ensure that assemblies always fit perfectly.
Validated print settings
Formlabs optimisation engineers tested hundreds of printed parts to ensure every material meets the most reliable standards straight out of the box.
Intelligent control systems
Six control systems precisely measure and maintain the temperature, resin level, print forces, and print status within your resin printer.
Long-lasting consumables
Robust hardware designed for years of use. Estimated lifespan: 75,000+ layers for the Resin Tank and 600k - 1.9M layers for Light Processing Unit 4L.
Factory Calibration
60-point calibration and quality control before your 4L resin printer leaves the factory.
Remote Monitoring
Monitor your prints and manage your printers from anywhere with an integrated camera, preventative maintenance reminders, and the free Formlabs Dashboard software.
The Backlight Unit generates an even, area-based projection of ultra-bright light using 145 LEDs and collimating lenses. It cures resin quickly and precisely, delivering blazing-fast print speeds.
The LPU 4L precisely masks the light from the backlight unit into a printed layer. Together, they enable you to print with extreme speed and accuracy. The LPU 4L is durable and easy to replace.
A patented micro-textured optical film allows airflow between the resin tank and the light processing unit. This significantly reduces peel forces, allowing for high-speed printing.
Six onboard control systems precisely measure and maintain the status of your resin printer. They ensure consistent performance and prevent common malfunctions.
The Form 4L Resin Tank uses a dual-layer flexible film stack to reduce peel forces, allowing for high-speed printing without compromising fine detail.
An integrated system that dispenses resin quickly and accurately with minimal waste. The Form 4L is one of the few large-format resin printers on the market to offer this automated feature.
