No, quite the contrary! The shape in the blue parts is quite trivial: 45 degree overhang + 5mm (?) bridge. You should be able to do 45 degree overhangs no problem and with no height limit. And bridges should also be possible quite easily, at least when they are short.stratogavster wrote:I'm certain my machine could never print that as seen from the holes previously displayed, though in theory they are less challenging than this floating horizontal feature.
You part on the other hand has overhang that goes gradually from 0 to 90 degrees. There's virtually no bridging. So, in order for your part to success the printer should be able to produce near horizontal overhangs which is not possible without some support material.
I would say the blue part in the previous post is quite easy (well, on edge of what is possible because of the 45 degree overhang but still very doable) but your part is impossible in that orientation without support.
