Form 4 established a new paradigm of accessible SLA 3D printing — the next-generation LFD technology enabled faster-than-ever print speeds without compromising on accuracy or reliability. Form 4L takes that same print engine and goes bigger: its build volume is 4.6x larger that of Form 4’s at 35.3 x 19.6 x 35.0 cm (13.9 x 7.7 x 13.8 in), and even 13% larger than its predecessor, Form 3L.

Compared to our previous large-format SLA 3D printers, Form 3L and Form 3BL, Form 4L is faster, more reliable, and easier to operate and maintain. The large-format Form 4L exposes each layer of liquid resin to the powerful Light Processing Unit 4L (LPU 4L) in an instant, compared to the dual laser motion of the Form 3L that had to trace each shape. When printing large parts or multiple smaller parts on the Form 3L, that dual laser process could add hours of print time. For Form 4L, it doesn’t matter how much of the build volume is covered — the light source will cure each layer instantly before moving to the next, resulting in large parts that will finish right after lunch.

Form 4L’s blazing fast print times enable these same projects to move ahead without downtime — running large parts or many smaller parts can now be done multiple times a day, so that innovation can move at the same pace as your team.

For anyone who relies on a 3D printer in their day-to-day work, large prints usually mean a slow-down in productivity. To check the design of a helmet prototype, you need to see it on someone’s head, to check the fit of an e-bike battery enclosure, you need to clip it onto the bike frame. If you’re printing these in multiple pieces, carving foam, or getting these machined, the difference in look and feel can slow down your iterative process — while your deadline keeps getting closer.
