Formlabs Form 4
3D Printer

Form 4 is a masked SLA printer (MSLA) powered by our Low Force Display™ (LFD) print engine. LFD features six custom hardware subsystems and sets a new standard for speed, reliability, print quality, and materials performance.

The LPU is a long-lasting consumable that has been tested to deliver consistent print performance throughout its lifetime.

Form 4 is the fastest SLA printer on the market with excellent reliability, print quality, accuracy, materials performance, and part size support. Most modern MSLA printers can deliver similar average print speeds (20-40 mm/hour) for their general-purpose materials. But they often have to sacrifice on reliability, print quality, supported part size, accuracy, and/or supported materials to achieve these speeds.

Yes, you can remove the parts from the Form 4/B build platform and use your existing Form Wash. But to fit the new Form 4 build platform which has 19% larger build area (note: 30% larger build volume), you’ll need to upgrade to the new Form Wash (2nd Generation). The maximum part size that can fit in the legacy Form Wash is 14.5 × 14.5 × 17.5 cm. Form Wash (2nd Generation) also has 3x more agitation and improved longevity allowing you to wash 67% more parts before replacing your solvent.

No. Formlabs redesigned the cartridge, resin tank, and build platform to achieve significantly better performance, lifetime, ease of use, and cost. To make those improvements, it wasn’t possible to make Form 4 printers backwards compatible with Form 3 series consumables.
