Formlabs Form 4L: Fast, precise large-format SLA printing
The Form 4L is a fast, precise SLA large format printer for prototypes and end products. Using LFD technology, it produces parts up to 5 times larger than the Form 4 - in record time and with the highest quality
We are pleased to introduce the new Form 4L - the large format SLA printer that takes the speed, precision and reliability of the Form 4 to a new level. The Form 4L and the biocompatible version Form 4BL utilize proven Low Force Display™ (LFD) technology, enabling the production of parts almost five times larger than the desktop version.
Ideal for human-scale prototypes, manufacturing aids or consumer products, the Form 4L delivers high-quality parts in record time. Even at full capacity, prints are typically completed within six hours.
Combined with new SLS powders and the expanded aperture of the Formlabs ecosystem, the Form 4L continues Formlabs' mission to empower users with powerful tools to turn ideas into reality, regardless of size or complexity.
The Form 4L enables the production of large, highly detailed parts from a wide range of materials within one day.
The Form 4L takes accessible SLA 3D printing to a new level by utilizing the innovative LFD technology of the Form 4 but offering an impressively larger build volume: At 35.3 x 19.6 x 35.0 cm, it is 4.6 times larger than that of the Form 4 and 13% larger than its predecessor, the Form 3L.
Compared to the Form 3L and Form 3BL, the Form 4L is faster, more reliable and easier to maintain. Thanks to the powerful Light Processing Unit 4L (LPU 4L), each layer of resin is cured in a single step instead of being traced with two lasers as with the Form 3L. This significantly reduces the printing time, regardless of how much of the build volume is used, and allows even large parts to be completed within a few hours.
While the Form 3L was a breakthrough for large-format SLA printing, its longer print times often slowed down iterative development processes. With the Form 4L, you can now print large or many small parts multiple times a day, allowing projects to progress faster and more efficiently - ideal for rapid innovation and productive workflows.
Large format parts in hours instead of days
The Form 4L offers a powerful printing system and an industry-leading materials library to deliver human-scale parts in just hours. The materials used match the look and feel of injection molded plastics. Manufacturers can produce prototypes for functional testing and consumer studies quickly and in-house, without having to hire external service providers.
Fast large format printing allows for more rounds of testing and more intensive consumer feedback, ultimately leading to better tested and validated products - all without delays or compromises.
Improved workflow: reliability and ease of use
Thanks to the powerful Light Processing Unit 4L, the Form 4L is not only faster than laser-based large format printers with multiple lasers, but also easier to maintain and less prone to errors. Fewer moving parts mean less maintenance, while long-lasting consumables, such as the Resin Tank and Light Processing Unit, are designed for over 75,000 and up to 1.9 million layers respectively.
The optimized design minimizes sources of error and eliminates the need for recalibration. High-quality materials and validated print parameters ensure consistent print quality - regardless of material changes.
The focus remains on the performance of the part, not the printer. Formlabs designed the Form 4L to deliver reliable results without extra effort, so you can focus on developing and optimizing your products.
Bigger, faster, but always on track
Customers such as Microsoft, Radio Flyer and Brose use the Form 4L to produce precise, large-format parts in high quality, accelerate iteration cycles and meet important deadlines.
The Form 4L eliminates uncertainties in the design and construction process: Will the print be ready on time? Can I still incorporate changes? Is it worth using a tool for the desired surface quality?
With the Form 4L, you are flexible. You can hold your meetings on time, test new functions or implement innovative ideas. The proven quality of SLA printing and the material diversity of the Formlabs ecosystem are now available on a larger and more powerful platform. The Form 4L is the fastest, easiest to use and most affordable large-format resin 3D printer in its class. It boosts your productivity and takes your designs straight from software to reality.
