Frequently Asked Questions
The Complete Package includes everything you need for an end-to-end large-format 3D printing workflow: the Form 4L Printer, a Form 4L Resin Tank, a Form 4L Mixer, a Form 4L Flex Build Platform, a Resin Pump (Form 4), a Form 4L Finish Kit (cleaning tools), automated post-processing hardware (Form Wash L V2 and Form Cure L V2), and a 3-Year Form 4L Pro Service Plan.
Yes. Formlabs offers the Form 4L in three configurations: the Basic Package, the Complete Package, and the Premium Package. Each tier bundles additional accessories and post-processing equipment. You can compare all three on the Form 4L product pages.
Yes. The Form 4L Complete Package comes bundled with a 3-Year Form 4L Pro Service Plan, giving you priority phone and email support, customized training, and fast hardware replacements to ensure maximum uptime.
The Form 4L offers a build volume of 35.3 x 19.6 x 35.0 cm (13.9 x 7.7 x 13.8 in), totaling 24.2 liters, making it well-suited for large parts and high-volume batch printing.
The Form 4L uses Low Force Display™ (LFD) technology, a next-generation MSLA print engine, that uses a powerful backlight unit with LEDs, custom light processing unit, release texture, and flexible resin tank to cure resin quickly and with high accuracy.
The Form 4L offers a significantly larger build volume, making it the right choice when you need to print bigger parts or multiple parts simultaneously. For smaller, more compact workflows, the Form 4 is a strong option. Formlabs provides a dedicated comparison page to help you evaluate your options.
The Form 4L is compatible with 23 industry-leading Formlabs resins spanning categories such as general purpose, impact resistant, high stiffness, temperature resistant, elastomeric, specialty, medical, casting, and dental. Third-party 405 nm photopolymer resins can also be used through Open Material Mode. Explore the full library on the Formlabs materials page.
The Form 4L is designed for general industrial use. For applications requiring biocompatible or dental-specific certified materials, Formlabs offers the Form 4BL Medical and Form 4BL Dental variants.
The Complete Package includes automated post-processing equipment—specifically the Form Wash L V2 and Form Cure L V2—alongside essential cleaning tools. This automates the washing and post-curing stages for large-format prints, ensuring consistent mechanical properties and smooth surface finishes with minimal hands-on labor.
Prints are prepared using PreForm, Formlabs' free print preparation software, which handles model layout, orientation, and support generation. You can also monitor and manage your printer remotely through the Formlabs Dashboard.
