Strange printing artifacts? Advice?


I printed a large (4.5"x2.5"x2") enclosure in Peopoly Next Grey at 100um. It turned out pretty well but there are some artifacts that are puzzling. I printed it straight on the build plate (no supports) and all 4 corners are torn/flaky – they were like this before I even touched the print (see the first picture). In the second picture you can see a raised band in the middle of the side that should be perfectly flat. This corresponds to features on the inside of the enclosure. Any idea why this happened? I don’t think it’s suction since I used lots of vent holes… Also, notice the vertical lines on that side – these are perpendicular to layer lines so what are they? Thanks!
