I don't understand why they have the extra material attached to them- perhaps the support was too flimsy and they wobbled about during the build. That said , I used the same orientation when I printed them before at 1-35 and they came out fine, which is why I did it this way this time. Hmmm
I can probably use them as long as they are fully loaded, but it's irritating to have it happen, and I need to know how to avoid it.
1. printing things 100% vertically is a problem, works for cylinders, but not for a lot of things.
2. the extra may well be the resin not getting enough time to move back under the build plate and stabilise before the next layer is ''cooked'',
3. try the angle trick from the above graph, it may work, and since the stuff will be at an angle, quicker to print, though it will need more support.
if you think about it , the centre of the fep sheet has to move further than the edges before it can release the layer attached to it, and so you need to have enough lift of the plate between layers to make sure they separate completely, and that, therefore, takes longer for the resin to flow below the plate before it goes back down.
the more material on the printing layer the more effort to remove and the bigger a ''bang'' when the sheet releases.
this causes the resin to have a wave motion.
there is a very fine line between faster and better
the calculations I have seen that the big names change are
1. distance plate rises after each layer ( retraction distance )
2. the amount of time the light delay is on for, to stop it from cooking the resin before everything is stable. ( light off delay )
3. the speed of retraction, too fast and the resin really makes waves.
I hope that makes sense
