Speed at scale. Large prints in under 6 hours.

Form 4L prints 2-4x faster than Form 3L, while offering 13% more build volume and a 6% larger maximum part length. This means that parts that might previously have been printed in multiple segments and reassembled can now be printed whole. Or, fit more small parts in one build for higher throughput.

Form 3L was already faster than large-format FDM 3D printers, but the technical innovations of Form 4L leaves them in the dust. Form 4L prints parts too big to fit in leading FDM printers, or fits larger quantities of batched parts for higher throughput — with most prints in under six hours. Printing the same parts with other 3D printing processes takes at least overnight, but often multiple days.

Versatile – Tackle any problem with our industry-leading materials, or use Open Material Mode

With Form 4L, we’ve redesigned and re-engineered our large format printer, cutting down print times for large prints to less than a workday—while achieving finishes that rival that of injection-molded parts.

Unmatched reliability. – Large format 3D printing you can depend on.

The technological improvements to Form 4L have directly addressed reliability. Beta testers and our in-house engineers put hundreds of prints to the test, pushing Form 4L to the limit. In addition to the LFD Print Engine, systems inside Form 4L work to ensure fast, accurate, and reliable prints.

Reliability starts at the factory, where every printer undergoes a 60-point calibration and quality control inspection. Once you start printing, systems and smart sensors inside Form 4L work to ensure reliable prints. Six integrated sensors precisely control resin temperature, resin level, print forces, and print status. High-speed conduction resin heating with infrared temperature sensing auto-heats resin to 25-45 °C (77-113 °F), depending on the material.
