Unfortunately, I think the print time cannot be shortened like Form 2 because of the LPU system.
As you know, Formlabs changed the X-axis control type of the laser from the galvanometer to the stepping motor with the LPU.
The movement of the galvo mirror is ultra-super faster than the stepping motor.
Formlabs got rid of the wiper time and shortened the lift-up time of the build platform, but the print time was significantly increased by the slow movement in X-axis.
Form 2 had many issues with detaching prints from the surface of the resin tank in case of any layer with large section area.
It was the biggest problem of the slide peeling type of Form 2.
Therefore, they needed to find any solution for reducing the peel force for the size of Form 3L.
As I think, how to solve the peeling force issue was more important than the print time.
