I've had tall prints that have very tall support structures fail because the support was a simple tower. On tall parts the tools need to do an aspect ratio calculation and see if they can build a pyramidal structure to support the high overhangs. A simple tower is not sufficient. Alternatives can be adding towers at intervals that attach to the design. This way the support is supported by the printed body which will give it more structural integrity. Eg, add a bridge every 20mm in Z if possible or do something algorithmicly to solve this. Maybe a diagonal at 30 degrees to the support tower from the body with small attachment/bindings to the body?

Hi, after using Cura a lot (and I've got to say it is incredibly good), one option I would like is a side-wall improvement. The sidewalls at the moment are basically done as a parallel layers of a filament layed down on top of each other (in the Z axis). This is structurally not sound as the parallel layers can de-laminate (all concentric layers can pull away from each other). What would improve this drastically is to alternatively have parallel and then serpentine on the walls. Eg layer 1 would have parallel (concentric) filament paths, the next layer (layer 2) would have a serpentine layer, Layer 3 would be a parallel (concentric) layer and so forth. This would bond the side walls together and make a structurally very sound bond. Thanks for the work on this. It really is fantastic. ?

Thanks for the response. Yes, I actually discovered that ZigZag does alternate layers and it's exactly what I wanted. Sorry for not realizing this. As I'm sure you guys know, there's a lot of features in Cura and it takes time to understand what they all do.

Hi, since we're on the topic of improvements (maybe this is hidden somewhere) ? I'd like to see an option to ZigZag alternate layers. Odds and evens if you like. The reason for this is that it will give better stability/strength. Ie an angle of 45 degrees only gives a consistent sheer line whereas 90 degrees alternate layers significantly improves the strength of a part. I personally think this should be the default configuration too!! If you rotate every layer by 90 degrees you will have a cross hatch from alternate layer builds. I must comment that this software is excellent BTW. ?
