Formlabs Form 3L SLA 3D Printer
The Large Format Formlabs Form 3L 3D Printer Compact Enough for the Office and Robust Enough for the Factory Floor
Take control of large-scale part production, increase your throughput, and bring your biggest ideas to life with the Form 3L, a cost-effective large format 3D printer that doesn’t compromise on the details.

Big Parts, Big Throughput
With a large build volume of 33.5 × 20 × 30 cm (13.2 × 7.9 × 11.8 in),
you can print one large model or many small parts in a single job.
Stop outsourcing large-scale prints
Work faster with a large format 3D printer that’s versatile enough to bring large scale fabrication in-house.
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’s ready to try on.

Perfectionism that scales
Two precision Light Processing Units inside the printer achieve consistent accuracy and detail across the entire build platform.
Intuitive and efficient
No specialized technicians required. The Form 3L offers automatic resin dispensing, simple print preparation software, and a thoughtfully designed interface.
High-resolution touchscreen interface:
A 5.5” interactive full-colour display minimizes error and eliminates the need for constant monitoring.
Automated print setup:
Tested over millions of prints, our free print preparation software, PreForm, automatically suggests optimal orientation, supports, and layout, with the ability to manually refine as needed.
Continuously evolving:
We believe the best products grow better over time, and we’re committed to continually evolving our hardware through software improvements.
Print around the clock
Whether you’re packing the build volume for batch production or printing bulky parts, the Form 3L maintains ideal print conditions for nonstop throughput, with minimal supervision.
Cloud monitoring:
Remotely monitor and manage your fleet of 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.
Incredible part quality
Stop sacrificing on quality for large-format prints. The Formlabs Form 3L provides the smooth surface finish and fine detail that stereolithography 3D printing is known for.
XY Resolution: 25μm
Laser Power: 250mW
Smooth surface finish:
Models printed on the Form 3L resemble polished injection-molded for realistic looks-like prototyping and consumer-ready end-use part production.
Consistent precision:
A system of lasers and mirrors ensures uniform print quality, for an XY resolution of 25 microns across the entire build platform.
High translucency:
With precise layer registration and smooth surface finish, translucent materials print clearer than ever, right off the printer.
Hassle-Free Materials Management
Choose from a wide range of advanced materials, developed specifically for Formlabs printers by in-house materials scientists. With simplified material switching and automatic resin dispensing, the Formlabs Form 3L allows you to walk away and focus on other work once your print job starts.
Many applications, one printer.
Print in over 15 functional resins to support a wide range of workflows on a single platform.
Switch materials in minutes.
Avoid the hassle and mess of purging materials with our swappable cartridge system, cross-compatible with other Formlabs SLA printers.
Automatic resin dispensing.
Our automated resin system dispenses resin as parts print. The Form 3L holds two cartridges of resin to avoid mid-print interruptions.
Low Force Stereolithography (LFS)™ uses a flexible tank and linear illumination to deliver groundbreaking print quality and printer reliability.
