Form4 Flex build plate detaching mid print

Hi everyone,

We recently purchased a new Build Platform Flex for our Form 4 machine and tried using it with Grey Resin V5. During the first print, we had a major failure: the flex plate detached mid-print, which triggered a “debris found by mixer” error.

At first, we assumed it was a one-time issue. We removed the plate completely and reattached it carefully.

However, on the second print, the plate flexed in the opposite direction and splashed resin toward the lead screw area. I cleaned the resin from the areas I could reach, but when I inspected the gap near the lead screw, I noticed a large blob of resin on the PCB. I immediately powered off the printer, and I am now unsure how to safely clean it.

We have already contacted Formlabs Support, but I wanted to ask here as well: has anyone else experienced a malfunction this severe with the Build Platform Flex?

I have attached a few images for reference.

Thanks,

Vardhamann

I am having the same issues. Mine was fine with the grey V5 resin, but with the clear V5, the flex plate seems to be stuck to the surface of the vat and then violently springs up, splattering the whole of the inside of the printer! I have ordered a standard build plate for the clear, but I really shouldn’t have to - I have not changed any settings at all from Formlabs standard.
