Thanks for printing the same model on yours.
Now, I see I am not alone on this ship…
Yes, your print seems also over-cured, but a little better than mine.
I have tested other standard resin types.
Unfortunately, all of them are in the almost same quality.
The worst one is with the white resin.
Shown below is printed with 0.05mm layer thickness, white resin on Form 2.
Shown below is with the same layer thickness, white resin on Form 3.
With clear resin on Form 3, and somewhat better.
With grey resin on Form 3.
I tried 0.1mm layer thickness with the grey resin, but worse than 0.05mm.
Please check the Formlabs PreForm release notes. You can find layer thickness setting improvement notes on version 3.1.1, but most of them seem not perfect at this moment as DKirch mentioned.
I had expected better results with the grey resin because Formlabs showed a feather(wing) print sample, but was disappointed by my result.
All prints seem pretty over-cured.
Shown below shows some dimensions of the test model.
However, the results are all pretty chunky.
As you mentioned, we cannot get any kind of clear gaps.
Form 2 print shows clear gaps. (below)
However, the current setting of Form 3 is very serious.
Now, I am totally tired of keeping cleaning my only one resin tank for changing resin types.
At this moment, I give up testing mine.
I believe it seems quite better to wait for the next PreForm update.
Anyone who has not received Form 3 yet, you do not need to envy people already got it.
We are struggling with it.
Also, Formlabs mentioned ‘the next few months’ for its software improvements.
When galvo mirrors or the main mirror of Form 2 is contaminated by fine dust, we usally get a very similar result.
However, Form 3 is new, so I hope that all the issues are due to parameter settings of the software, not due to the LPU or the foggy resin tank film.
