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.
