Formlabs Form 4L
The Form 4L is a large-format SLA 3D printer with ultra-fast masking, combined with an extensive material library and precise, reliable printing tools. Turn your ideas into reality faster than ever with an easy workflow, high reliability, and excellent detail quality through the Form 4L ecosystem.

The Form 4L’s printing speed is driven by Formlabs’ new Low Force Display™ technology, a powerful combination of ultra-high-power LEDs, converging lenses, optical filters, and a robust liquid crystal display (LCD). Together, these components rapidly cure each layer of resin—regardless of part size or detail complexity. With tight tolerances, parts printed with any type of resin on the Form 4L will always match your design specifications, ensuring fast, accurate, and reliable prints.
The Form 4L utilizes high-precision directed lighting with pre-adjusted anti-aliasing functionality, delivering resolution finer than the pixel level. This ensures that even the most intricate details are captured with exceptional clarity.
Smoothest Surfaces: Thanks to its low force peeling technology and light-touch support, the Form 4L produces parts with ultra-smooth surfaces, minimizing imperfections and enhancing the quality of every print.
Most Accurate Assemblies: With an XY dimensional tolerance of ±0.15%, the Form 4L guarantees that all assemblies fit together perfectly, maintaining high precision for even the most complex components.
