Formlabs Form 4L and Form 4BL Print Expand 3D Print Volumes

Formlabs’ large-format Form 4L and Form 4BL 3D printers offer the speeds of the Form 4 printer but with larger build volumes. The Form 4BL is the biocompatible version of the 4L and similarly scales up the capabilities of the Form 4B.

Built on the company’s low force display (LFD) print engine, Form 4L delivers a 99% print success rate. The system is designed to enable large-scale parts but also smaller parts at high volume.

According to Formlabs, the Form 4L features print speeds up to 80 mm per hour, enabling large-scale prints in under six hours. The build volume is nearly five times larger than the Form 4, and the machine can print thousands of parts per day at low cost per part. A new cartridge design, implemented in the Form 4L, reduces plastic waste by 63% and delivers faster resin dispensing.

The Form 4L is compatible with at least 23 materials, offering choices for application-specific properties such as durability, rigidity, biocompatibility and flame retardant characteristics.

“We believe in driving innovation forward by providing the freedom and flexibility users need to bring their ideas to life. Form 4L will enable users to solve bigger problems and bring big ideas to life at lightning-fast speeds, regardless of scale or complexity,” says Formlabs CPO Dávid Lakatos.

Agostino LoBello, product design engineer at Radio Flyer, is pleased with the updated printer. “The speed and dimensional accuracy have made a big difference in our shop,” LoBello says.

Additionally, Formlabs introduced new printer accessories, two new selective laser sintering (SLS ) materials, five new PreForm features and new postprocessing solutions. Formlabs also announced it is opening up its developer platform to enable more freedom and flexibility.
