Twice as powerful a laser
Two Light Processing Unit (LPU)staggered inside the printer use a compact system of lenses and mirrors to provide accurate and replicable prints.
Faster printing:
The two LPU work simultaneously along an optimized print path to efficiently track parts of any size.
Sharp and clean details:
Each high power density laser is passed through a dimensional filter to ensure a sharp laser dot.
Homogeneous precision:
A parabolic mirror ensures that the laser prints perpendicularly to the printing surface, ensuring uniform print quality across the entire printing platform.

Non-stop prints
Integrated sensors help to maintain ideal printing conditions and send alerts on the status of the device.
High material capacity:
The Form 3L can contain two easily interchangeable resin cartridges, preventing interruptions during large print jobs.
Closed-loop calibration:
Optical sensors constantly correct scale and power and are even able to detect dust.
User-replaceable components:
The Light Processing Unit, resin tank, rollers and optical window can be replaced in-house, reducing the need for replacement printers.
