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.

Stunning parts that always fit.
