Form 4L. Big Parts. Blazing Fast.

Form 4L’s speed is driven by Formlabs’ 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 resin layer 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.

*Typical print time using 80th percentile print height (53mm), 100 μm layer height, and any material.
