Big Parts, Blazing Fast
Large prints in under 6 hours. 4.6x larger build volume than Form 4.
Form 4L is a blazing-fast large-format masked SLA 3D printer that combines an industry-leading materials library with a reliable, accurate print engine. Turn your biggest ideas into reality faster than ever with easy workflows, leading reliability, and stunning part quality using the Form 4L ecosystem.
Form 4L’s speed is driven by Formlabs’ new Low Force Display™ Print Engine, a powerful combination of ultra-high power LEDs, collimating lenses, optical filters, and a robust liquid crystal display. Together they cure each layer of resin rapidly — regardless of part size or quantity. With tight tolerances, parts printed in every resin on Form 4L will match your design parameters, every time.

Complete Your 3D Printing Experience
- Print - During printing, light selectively cures a liquid resin to create the shape of your part.
- Wash - Automated washing in an agitated bath of solvent eliminates uncured resin for a flawless surface finish.
- Cure - Exposure to heat and 405 nm light finalizes part properties by completing the chemical reaction started during printing.
Fast, Clean SLA Post-Processing
Form Wash
Form Wash and Form Wash L provide thorough cleaning with powerful agitation to ensure residual resin is completely removed. After the preset wash cycle, the parts are automatically lifted from the bath to air dry.
Form Cure
Form Cure and Form Cure L use powerful LEDs, convective heating, and validated presets to achieve optimal mechanical properties with speed and precision.
Post-curing improves your part on a molecular level. 405 nm light initiates a reaction that cross-links the individual polymers, creating an interconnected, isotropic, and 100% dense final part.
- Higher strength and stiffness
- Higher surface hardness
- Higher toughness
- Higher temperature resistance
- Better creep resistance
