A large format 3D printer compact enough for the office and robust enough for the factory floor

Take control of large-format prototyping and bring your biggest ideas to life with the Form 3L, a cost-effective large scale resin 3D printer that doesn't compromise on the details. Built on Formlabs' Low Force Stereolithography (LFS)™ technology, the Form 3L pairs a 33.5 × 20 × 32 cm build volume with two precision Light Processing Units, so you can fabricate full-scale, bulky prototypes or detailed models with the smooth surface finish and fine detail that stereolithography is known for. It prints around the clock with minimal supervision, and it is the first accessible large resin 3D printer to combine unprecedented reliability, quality, and ease of use.

Why choose Form 3L?

• Big parts, big ideas — a 33.5 × 20 × 32 cm (13.2 × 7.9 × 12.6 in) build volume of 21.4 liters lets you print full-scale bulky prototypes, human-scale models, or detailed parts in one build.
• Stop outsourcing large prints — bring large scale fabrication in-house and meet critical deadlines without prohibitive costs.
• Perfectionism that scales — two precision Light Processing Units achieve consistent accuracy and detail across the entire build platform, with 25 µm XY resolution.
• Intuitive and efficient — no specialized technicians required thanks to automatic resin dispensing, simple print preparation in PreForm, and a 5.5″ full-color touchscreen.
• Advanced materials — 23 industry-leading Formlabs materials, or third-party materials using Open Material Mode, each with optimized print settings for industry-leading print success.

Life-sized prints for larger-than-life ideas

The Form 3L is large enough to print human-scale models — like a prototype of a helmet that is ready to try on. Black Diamond Equipment uses the Form 3L to prototype climbing helmets at 1:1 scale to test for form and fit, producing several iterations per week in-house and reducing costs. Their full-size helmet prints in Draft Resin in about 8 hours at a print cost of roughly $88.

• Full-scale prototypes — helmets, enclosures, shovels, and other bulky consumer products at 1:1 scale for form and fit testing.
• Functional parts — nozzles, jigs, and fixtures printed in a single build instead of being split and glued.
• Detailed models — the same fine features and smooth surfaces as a desktop SLA printer, scaled up to large format.

Print time and cost vary based on part geometry, material, layout, and orientation.

Professional parts. Stop sacrificing quality for size.

Stop sacrificing on quality for large-format 3D prints. The Form 3L provides the smooth surface finish, fine details, and high-performance material properties that resin 3D printing is known for. A system of lasers and mirrors ensures uniform print quality, for an XY resolution of 25 microns across the entire build platform.

• Smooth surface finish — models printed on the Form 3L resemble polished injection-molded parts and can reach high translucency for realistic looks-like prototyping.
• Consistent precision — 25 µm XY resolution and 25–300 µm layer thickness (available settings vary by material) across the whole build area.
• Advanced materials — each Formlabs material comes with optimized print settings to guarantee industry-leading print success and reliability, as well as standout mechanical, thermal, or biocompatible properties.

Intuitive and efficient

No specialized technicians required. The Form 3L offers automatic resin dispensing, simple print preparation software, and a thoughtfully designed interface, so anyone on the team can go from file to finished part.

• High-resolution touchscreen interface — a 5.5″ interactive full-color display minimizes error and eliminates the need for constant monitoring.
• Automated print setup — tested over millions of prints, free PreForm software automatically suggests optimal orientation, supports, and layout, with the ability to manually refine as needed. Advanced users can customize print settings to tailor print performance.
• Continuously evolving — Formlabs is committed to continually improving the hardware through software updates, so the printer gets better over time.

Print around the clock

The Form 3L constantly monitors print performance so you can focus on bringing your most creative ideas to life. Integrated sensors help maintain ideal print conditions for nonstop throughput with minimal supervision.

• Cloud monitoring — remotely monitor and manage your fleet of large format 3D printers with the online Dashboard.
• Fast-printing material — Draft Resin balances detail and speed to save time on bulky prototypes and enable quick iteration.
• In-field repairs — the Light Processing Units, rollers, optics window, and other components can be replaced in-house to ensure 24/7 uptime.
• Two resin cartridges — the Form 3L holds two cartridges of resin and dispenses automatically as parts print, avoiding mid-print interruptions.

Advanced materials for industrial-quality parts

Bring your parts to life with the most comprehensive library of high-performance materials on the market, developed specifically for Formlabs printers by a team of in-house materials scientists. With simplified material switching and automatic resin dispensing, the Form 3L lets you walk away and focus on other work once your print job starts.

• 23 Formlabs materials — industry-leading resins with optimized, validated print settings, plus third-party materials using Open Material Mode.
• Switch materials in minutes — avoid the hassle and mess of purging materials with the swappable cartridge system, cross-compatible with other Formlabs SLA printers.
• Automatic resin dispensing — the automated resin system dispenses resin as parts print.
• Total freedom with Developer Platform — enhance your printer's versatility with certified third-party materials, customizable print settings, or the ability to experiment with any unvalidated 405 nm photopolymer resin (optional, paid license).

Industry-leading software

1. Prepare your print in PreForm — tested over hundreds of millions of prints, free PreForm software automatically suggests optimal orientation, supports, and layout to save time during print setup.
2. Load two cartridges and start printing — automatic resin dispensing and integrated sensors keep the print running with minimal supervision.
3. Monitor from anywhere — track prints and manage your printers through Dashboard in the cloud.
4. Release, wash, cure — remove parts from the build platform, then finish them with Form Wash L and Form Cure L for consistent, high-quality results.

The Form 3L ecosystem: part of the Formlabs experience

Formlabs is known for designing end-to-end additive workflows you'll be excited to use, and the Form 3L brings that experience to large format 3D printing. Streamline your workflow and consistently produce high-quality parts with the automated large-format post-processing solutions Form Wash L and Form Cure L. Build Platform 2L with patented Quick Release Technology (sold separately) releases parts from the build platform in seconds — no tools required — and a team of 3D printing experts is available for support when you need it.
