Professional MSLA printer with a 60-LED Low Force Display light engine, 50 micron pixels and cartridge resin handling.
200 x 125 x 210 mm (Formlabs quotes 5.25 litres)
Advertised dimensions; check usable space and variants.
Low Force Display masking LCD with a 50 um pixel size and pre-tuned anti-aliasing. Formlabs does not publish the screen diagonal or pixel count
Published resin-display specification.
Starting at $2,625.00 at GoEngineer, in stock, checked Aug 2026. Formlabs sells the printer as part of packages (Form 4 Complete Package etc.), so package prices are much higher than the printer-only figure
Dated listing, not a live offer. Read the configuration and region.
Understand the hardware, explore compatible changes and find a diagnostic starting point when something goes wrong. Expand the specification sections for every recorded value, condition and original reference.

| Variants & sibling models — and how to tell them apart (spec-contamination risk) | Three machines share this platform and are constantly conflated. Form 4: 200 x 125 x 210 mm, 50 um pixels, 18.3 kg, 480 W, one resin cartridge, NOT biocompatible. Form 4B: identical hardware but validated for 38 Formlabs materials including 15 biocompatible.

Use the manufacturer’s firmware and cartridge-identification/RFID checks before following the model-specific hardware replacement branch.
Applies to: Form 4 generation; do not assume Form 4 and Form 4L cartridge-floor service parts are interchangeable.
Formlabs supplies actual CAD/STL files for storing the build platform on a wall mount between jobs.
Applies to: Use the Form 4 generation design and the manufacturer’s material/mounting instructions.
The official pump replaces the cartridge supply with a supported 5 L resin-container workflow, reducing cartridge changes.
Applies to: Compatible with Form 4; check the specific resin’s pumping-system eligibility and material-change procedure.

This guide presents the catalog’s sourced record for this exact model. Source dates belong to each reference; a page update does not mean every specification has been rechecked.
Prices are dated listing snapshots, with configuration, regional and sale conditions. They are not current offers. Unknown values remain unfilled.
Firmware, variants and available accessories can change. Read the original reference before making a purchase or planning a process.
Firmware, modifications and troubleshooting links are checked against the model and stated hardware or firmware revision. A creator’s compatibility claim is not a fit test by this site. Official troubleshooting describes a diagnostic route; individual reports do not establish a failure rate.
