Industrial 3D printer meets blazing speed

Form 4 is a blazing fast masked SLA (MSLA) resin 3D printer that combines an industry-leading materials library with a reliable, accurate print engine. Powered by Formlabs' Low Force Display™ (LFD) technology, Form 4 completes most prints in under two hours — and print time stays about the same whether you're printing one part or a full build platform of many. Turn your ideas into reality faster than ever with easy workflows, leading reliability, and stunning part quality.

Why choose Form 4?

• Blazing fast — most prints finish in less than 2 hours, with a maximum print speed of 100 mm/hour. Iterate 3× faster and reach production rates of about one minute per part on a full build.
• Versatile — 23 industry-leading Formlabs materials spanning rigid, tough, general purpose, flame retardant, silicone, elastic, ceramic, and castable resins, plus third-party 405 nm resins via Open Material Mode.
• Intuitive — anyone can learn the full print workflow in about 15 minutes with PreForm's one-click print setup and no-hassle cartridges and tanks.
• Reliable — a 98.7% print success rate measured by an independent global leader in product testing, so you stop coming back to failed prints.
• Accurate — ±0.15% XY dimensional tolerances, 50 µm pixel size, and pre-tuned anti-aliasing produce parts that rival injection molding in detail, surface finish, and fit.

Get more done with most prints in under 2 hours

Form 4's Backlight Unit generates a uniform area projection of ultra-high-power light using 60 LEDs and collimating lenses, curing an entire layer at once. Combined with a low-force release texture, a flexible-film resin tank, and high-speed automatic resin handling, Form 4 prints up to 5× faster than Form 3+ — and its print time barely changes as you add parts to the build platform.

• Prototyping — increase your productivity by 3×. Say goodbye to iterating after hours; design, print, and test multiple iterations in a single day.
• Production — about 1 minute per part on a full build platform. Reach peak production efficiency for manufacturing aids, jigs and fixtures, and end-use parts.

Produce stunning parts that always fit

Form 4 delivers the sharpest details, smoothest surfaces, and most accurate assemblies of any Formlabs printer to date — rivaling injection molded parts.

• Sharpest details — highly collimated light and 50 µm pixel size with pre-tuned anti-aliasing for subpixel resolution.
• Smoothest surfaces — lower peel forces and light-touch supports leave minimal marks and a clean surface finish.
• Most accurate assemblies — ±0.15% XY dimensional tolerances so assemblies always fit.

Tackle any problem with industry-leading materials

Form 4 supports 23 Formlabs resins — rigid, tough, general purpose, flame retardant, silicone, elastic, ceramic, and castable — with new materials in development. Open Material Mode (included in the Form 4 Premium Package, or sold separately) unlocks third-party 405 nm photopolymer resins for even more flexibility.

• Rigid — ultra-stiff, high-strength, glass-filled resins for enclosures, fixtures, and load-bearing parts.
• Tough & Durable — impact-resistant materials that simulate polypropylene and ABS for functional prototypes.
• General Purpose — fast, affordable Clear, White, Grey, and Black resins for everyday prototyping.
• Flame Retardant, Silicone, Elastic — specialty resins for gaskets, seals, wearables, and self-extinguishing parts.
• Ceramic & Castable — for jewelry investment casting and high-temperature applications.

Unmatched reliability. Stop coming back to failed prints.

Form 4 was measured to have a 98.7% print success rate by an independent global leader in product testing. Six upgraded sensors precisely control resin temperature, resin level, print forces, and print status, and every printer is factory calibrated so you get consistent results from the first print.

• Validated print settings — every Formlabs material ships with tuned, tested print settings.
• Intelligent control systems — high-speed conduction resin heating with infrared temperature sensing, ultrasonic resin level sensing, a Z-axis force sensor, a resin cartridge load cell, and a printer leveling sensor.
• Long-lasting consumables — the Form 4 Resin Tank is rated for 75,000+ layers with any Formlabs material (roughly 190 average-height prints).
• Remote monitoring — an integrated 5 MP camera provides live views, timelapses, and print history through Dashboard, and can be easily disabled, covered, or removed.

So intuitive that anyone can learn to print in 15 minutes

1. Import your model and prepare your print — smart auto-orientation, advanced support generation, and live printability checks in free PreForm software.
2. Load a material and click print — validated print settings, no-hassle cartridges and tanks, and automatic resin dispensing.
3. Remove, wash, cure — quick-release part removal, automated part cleaning with Form Wash, and precision post-curing with Form Cure for peak material properties.
4. Finish your part — light-touch supports for quick, clean support removal, then optional sanding, coating, or painting.

The Form 4 ecosystem: complete your 3D printing experience

Form 4 works seamlessly with Form Wash and Form Cure to automate post-processing. Form Wash agitates parts in IPA or Formlabs Resin Washing Solution to remove uncured resin, and Form Cure delivers precise, heated UV post-curing so parts reach their final mechanical properties.

Choose the Form 4 package that fits your workflow:

• Form 4 Basic Package (this product) — everything you need to start printing: Form 4 printer, Resin Tank, Mixer, Build Platform, and Finish Kit. Ideal if you already own post-processing equipment, with optional 1-, 3-, or 5-year Pro Service Plans.
• Form 4 Complete Package — adds Form Wash V2, Form Cure V2, a Solvent Pump, and the Form 4 Flex Build Platform for a fully automated print-wash-cure workflow, plus a 3-year Form 4 Pro Service Plan.
• Form 4 Premium Package — built for higher throughput: two Form Wash V2 units, two Flex Build Platforms, Finishing Tools, Open Material Mode, and a 5-year Form 4 Pro Service Plan.
