My experiments are leading to try and create a script file that will use arc matching of segments from surfaces. From my perspective the problem lies in the file type we are slicing. I don't really care which slicer I use what I really don't like is the extensive CAD work needed to trick the slicer into doing what I want. I have tried numerous ways to design aircraft parts and slice with prusaslic3r, Cura, simplif圓d, etc. I have been experimenting with these problems also. It would be really nice if Prusaslicer could do the same as Cura in printing these single width internal structures, but do so without the unnecessary travel moves! Here is an example of the problem in engine pod 2.

Most parts on the Icon A5 printed nicely on my Prusa Mk3S, but Engine pod 2 was terrible. Specifying X,Y starting co-ordinates in a central position in the part can reduce the travel moves somewhat, but especially with complex parts, it doesn't eliminate them. Worse still, these travel moves also result in the restart prime plastic being used up, which causes under-extrusion at the start of the layer. The real problem for me in using Cura, is that it has a nasty habit of inserting ridiculous numbers of travel moves that do nothing other than deposit a zit on the surface of the part. Weight is everything in this hobby and we are continually looking for either lighter materials or methods of design/slice/print that yield lighter results. This is about half the weight of a similarly sized 3DLabPrint plane. I have just finished printing the Icon A5 from and it came in at a relatively lightweight 427gms all up for the print job. So it appears that Cura is the only slicer that can handle this type of design. RE: Trying to slice RC plane files in PrusaSlicer Anyone far smarter than me have an idea on how to slice this with the PrusaSlicer? I was told this is due to it being single wall thickness structure and the slicer doesn't understand that. once sliced, all the internal structure is gone. Attached is what the file looks like when imported and also when sliced. Would love to slice these in Prusaslicer and was wondering if anyone had any ideas.

I tried slicing the parts in simplif圓D and also Prusaslicer and sure enough, I can't figure it out. After talking with the designer they insisted that due to the way the plane was designed, it can only be sliced in cura as there is a surface setting in cura that doesn't exist in any other slicer. There is a new plane that was released in the last few weeks by a site called planeprint. I've printed both the planes from 3Dlabprint as well as those from eclipson. So for starters, I've printed quite a few RC planes already. Trying to slice RC plane files in PrusaSlicer
