Formlabs Form 4L Benefits

low force display 3d printing

Low Force Display Printing

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 4 will match your design parameters, every time.

Stunning Parts

Parts with a surface finish that rivals injection molding.

Sharpest details: highly collimated light with pre-tuned anti-aliasing for subpixel resolution.

Smoothest surfaces: lower peel forces and light touch supports.

Most accurate assemblies: ±0.15% XY dimensional tolerances so assemblies always fit.
