I’ve been tracking my Form 3 and even though I’ve only done 700 mL worth of prints it has used 1L of resin. I’ve repeated this same thing over 3 cartridges.
So the Form 3 is using about 43% more resin than PreForm says it will when it prints.
I notified Formlabs of this project (as it was also doing it with Tough resin) back in February and then were working on investigating it but then Covid hit.
It should be noted that the Form 3 uses more resin to make the same exact print than a Form 2 does if you are using Tough or Tough 2000. We’ve weighed the prints to provide and Formlabs has been testing this as well.
It was all in motion and then Covid hit and so that testing has been delayed to figure out why.
