Formlabs Form 4

Description

The Form 4 replaces the Form 3+ laser engine with Low Force Display (LFD): an array of 60 high-power LEDs and a large-area optical stack that cures a whole resin layer at once, at print speeds up to 5x the previous generation. Most parts under 53 mm tall finish in under two hours, and print time stays roughly constant whether the plate holds one part or many, because the platform cures per pass instead of tracing each part with a laser. A 200 × 125 × 210 mm volume and 50 micron pixel size with pre-tuned anti-aliasing hold ±0.15% XY tolerances, so batches stay consistent enough for assemblies that need injection-mold-like fit. Resin is dispensed automatically from sealed cartridges, light-touch supports come off more cleanly, and a validated success rate around 99% (independently measured at 98.7%) cuts failed prints and hands-on watching. It connects over Wi-Fi, Gigabit Ethernet or USB-C and works with PreForm and the cloud Dashboard for remote monitoring and fleet management.
