Hello, before jumping to the new model, I would like to know how the Formlab 4 handle suction effect having a flat exposure surface in comparison to flexible formlabs 3+.
Let me show these perfect examples build without support and custom profiles on hightemp.
I have the chance to play for months on other brand printer with 14K mono resolution, but it cannot handle cup suction not even close to formlabs 3b+. And I suspect formlabs 3+ can handle better because the flexible fep + raster, Am I right ?
Cheers

From my experience the Form 4 seems to handle cups a bit worse than the Form 3 - which is also reflected in Preform, where the cupping algorithm flags cups that would otherwise not be flagged on the Form 3 in Preform.
Practically speaking though, I haven’t done an in depth comparison between them so I don’t really know exactly how much worse it is.

Hey @glococo , thanks for your question! You can enable a feature called “Cup Mitigation” using PreForm settings editor to significantly mitigate cup issues. This will slightly slow down your print, though with this feature enabled the Form 4 is still much faster than the Form 3!
You can learn more about PreForm Print Settings Editor here and what Cup Mitigation is below:
Hope this helps, don’t hesitate with more questions!

Not always possible depending on geometry, but you can add small vent holes (down to 0.5mm) in the offending areas.
