I printed it just to see what would happen. I'll be damned that it actually tried and succeeded to print this rather ugly box lid. Imagine that.
Box lid - Printing over air (No support)
Box lid - Printing over air (No support)
I just wondered what would happen if I ran this box lid through Cura. Would it not slice at all? Would it force me to enable 'support'? Well Neither is the answer..

Re: Box lid - Printing over air (No support)
Yeah, I did an over air print that actually sort of made it. The problem I found it did not bind to the lower layers very well.
One thing I thought about was if there were optimal patterns that would work over air. Like a quick triangular pattern on the edges or something. As it ingresses it would keep building on that pattern. Also, other slicers might do better or if there is an option to lay down 2 layers on each output. If that were the case then it would try to bind to an already hot line it just laid down. That way it would maybe build a better first layer? Heating the bed hotter might help too.
Then there is always the option to build some support structure too.

Re: Box lid - Printing over air (No support)
My output tends to be similar with big areas - one or two layers of birdnest before it gets settled down and I get a decent layer. I've generally gotten around it by parting my models to have separate tops which join back on, or printing the birdnest where it won't be seen.
I need to try again now that I have the layer fan set up. Results with ABS on the calibration set with overhangs and bridges so far have been promising.
Best, I think, would be some smarter bridging support in a slicer - being able to build in three or four bridge support layers (which will be removed later so who cares if they are birdnest) with the fan running, one or two thin grid interface layers, then the proper bridge. I'd much prefer this to what looks like the current alternative - build up a tonne of support from the base all the way up to the top. Of course, the full support is needed when it's an overhang that doesn't have another side to it and you can't do the bridge.
