hey there,
I figured around with the Formlabs form 1+ and seem to have very stable printing results after cleaning all mirrors on the machine. So I made a Quotation after as I felt safe and started as I got the order.
In parallel, i also ordered a new tank and new bottle of resin (White).
I just started printing some of the requested models with the existing tank and resin (black).
As I got the new tank and resin, I also started using it. First two parts, there were very Little defects on the part. That was not a big issue. So I was able to assemble them. But as I did the last requested part, I needed to try fife times up to now. Different orientations and different volume. Also I tried to cut the part into two, without having any success.
So I also decided to clean all mirrors again. Not only the mirror in front, all optical Units. I also tryed to step back to black material. This also leads to exploded parts. At the Moment, i dont have a good idea, how to continue the rootcause Analysis, as I already cleand everything and also changed material and resin tank.
Attached you can see the Pictures of the results in chronological order, starting with the newest prints to the older ones in Black.
I also reduced accuracy/Resolution from 0,05mm to 0,1mm but without success.
Any Ideas?
