Enter the Formlabs Form 4L, a resin 3D printer that’s redefining what’s possible for professionals who demand the best. Unlike filament-based printers that struggle with fine details, the Form 4L delivers stunning resolution down to 25 microns—think near-injection molding quality. But it’s not just about the details; this printer is designed to streamline workflows, handle high-capacity production, and adapt to a wide range of industries, from engineering to healthcare.

If you’ve been searching for a tool that can elevate your projects and save you time in the process, this might just be the fantastic option you’ve been waiting for. With its focus on precision, efficiency, and reliability, the Form 4L surpasses traditional filament-based printers, offering a robust solution for creating high-resolution outputs. Its advanced features and exceptional performance make it a valuable tool for professionals seeking consistent, high-quality results.



The Formlabs Form is a professional-grade resin 3D printer offering high precision (up to 25 microns), efficiency, and exceptional quality, ideal for industries like healthcare, engineering, and manufacturing. Resin 3D printing (SLA) surpasses filament printing by delivering finer details, smoother finishes, and near-injection molding quality, making it suitable for applications requiring high accuracy. Key features include a large build volume, automated resin dispensing, UV light curing, user-friendly software, and durable build quality, optimizing workflows and productivity.

It supports a wide range of specialized resins, such as engineering, flexible, and biomed resins, catering to diverse applications like prototypes, medical devices, and industrial parts. Though priced at $20,000 for the Form 4L kit, its advanced capabilities, efficiency, and long-term reliability make it a valuable investment for professionals seeking high-quality 3D printing solutions. Resin 3D printing, also known as stereolithography (SLA), uses UV light to cure liquid resin into solid layers, allowing the creation of intricate details that filament-based printers cannot achieve.

While filament printers are versatile and cost-effective, they are limited by their nozzle size, typically producing layers no finer than 200 microns. In contrast, the Form 4L achieves resolutions as fine as 25 microns, delivering results comparable to injection molding. This level of precision makes resin 3D printing the preferred choice for applications requiring exceptional surface finish and accuracy, such as dental molds, medical devices, and detailed prototypes.

The Form 4L is engineered to streamline workflows and enhance productivity, offering a range of features tailored to professional needs: The spacious build area accommodates larger projects or multiple smaller parts in a single print run, making it ideal for high-capacity production. Advanced UV curing technology ensures uniform layer curing, resulting in consistent quality and faster production times. Dual resin slots enable uninterrupted printing, reducing downtime and optimizing material usage.

The PreForm software simplifies print preparation with intuitive controls, making it accessible for both beginners and experienced users. Designed for reliability, the Form 4L is built to withstand heavy, continuous use, making sure long-term performance. These features collectively make the Form 4L a reliable and efficient choice for professionals aiming to optimize their 3D printing processes.

Resin 3D printing involves additional steps after the printing process to achieve the final product. The Formlabs ecosystem supports this with dedicated wash and cure stations, simplifying post-processing and making sure consistent results.

After printing, parts are washed in a solvent to remove excess resin, followed by UV curing to enhance their strength and stability. These tools not only reduce manual labor but also improve workflow efficiency, allowing professionals to focus on innovation rather than tedious post-processing tasks. By integrating these steps seamlessly, the Form 4L minimizes downtime and maximizes productivity.

A standout feature of the Form 4L is its compatibility with a wide range of specialized resins, each designed for specific applications. This versatility allows professionals to address diverse industry needs with precision: Durable materials, such as glass-infused and ABS-like resins, are ideal for functional prototypes and industrial parts. These resins are perfect for creating silicone-like parts or products requiring flexibility and elasticity.

Biocompatible materials tailored for medical and dental applications ensure precision, safety, and compliance with industry standards. This extensive range of resins enhances the Form 4L’s adaptability, making it suitable for applications ranging from aerospace components to healthcare solutions. The Form 4L excels in rapid prototyping and small-scale production, offering consistent quality and speed.

Its ability to produce hundreds of parts daily makes it a cost-effective alternative to traditional manufacturing methods like injection molding. Professionals in industries such as healthcare, engineering, and product design benefit from its precision and efficiency, which significantly reduce lead times and production costs. Whether you’re creating dental molds, medical devices, or intricate prototypes, the Form 4L delivers high-quality results that meet the demands of innovation-driven industries.

The Formlabs Form 4L is positioned as a premium product, with the standard Form 4 kit starting at $5,500 and the larger Form 4L kit priced around $20,000. While the upfront cost may seem substantial, the printer’s advanced capabilities, efficiency, and reliability justify the investment for professionals and businesses requiring high-quality 3D printing solutions. By delivering precision, productivity, and versatility, the Form 4L offers significant long-term value, making it an essential tool for those prioritizing quality and efficiency in their workflows.
