Hello everyone, I want to print an RC airplane from 3dlabprint.com with my X1.
I have already found some problems such as the first layer with 2 wall loops and the next layer with one wall loops. Currently I don’t understand how I can preserve the inner frames of the wings and at the same time set the infill to 0%. I can’t find a setting for this in the Bambulab Slicer.
I added a photo for understanding.
Can anyone help me here or have any of you already printed an RC airplane and can generally help me with the settings?
Thanks in advance and greetings Thomas
Hi Mike,
thanks for your quick answer.
Sorry, that I hadn’t found this part of the wiki yet.
I’ll read it now and try it out.
Thank you.
Thomas
If the internal bracing of the wing is part of the CAD model, the infill settings have nothing to do with them and your problem is something else. But some RC models use low infill percentages to create those internal braces. If you set infill to 0% and everything inside the wing (except for the spar tubes) goes away, the model is designed to use infill. Set it to a low value and print it.

But that’s not the case of 3dlabprint models, this advice could be confusing.
If you set up the slicer correctly, all internal structures should be sliced perfectly. My X1C is in the middle of printing the WACO (2.4kg printed weight), so I think I know what I’m talking about. 
In addition to 1 perimeter, 0 bottom solid layers, 0 top solid layers, 0% infill (which are quite obvious) there are some other essential parameters to be set: wall generator Arachne, slicing mode to Even/Odd, order of walls to Outer/Inner/Infill, ensure vertical shell thickness to Off and slice gap closing radius to 0mm. Maybe there are some others, but these are essential.
You may add height modifier increasing number of perimeters to 2 for 0mm-2mm (or 0mm-3mm).
I think both of you are right,
the problem is the spiral vase mode.
I think I first click it after reading the instructions (probably I’m wrong), but switch off the mode fixed my problem.
I haven’t tried the Arachne Mode, outer/inner/wall and the vertical shell thickness for this yes, but I will test it with the next print.
Thanks for your help 
Hi,
it works for most parts now. But I still have problems with overhang angles. 3dlabprints gives 3 upper layers as a solution to close these gaps. This solution close the gaps at my wingtips but the transitions are bad. It doesn’t work for the part of the photo. I have tried it with a lot of changes and support W. I have no idea to fix it. Does anyone know what I´m doing wrong?
Another question, can I use a height range modifier for two wall loops at the first layer and an other modifier for an other modifier to create 3top shell layers at a certain height, so that the top layer are not affected by the change?
You can use any number of height range modifiers with different settings as long as their heights don’t overlap. But I think the user interface doesn’t allow overlapping height range modifiers, so you should be safe with that.
Use “Ensure vertical shell thickness” setting as well. Also consider lowering layer height for height ranges with steep overhangs. 0.15mm worked for me.
Hi, that helps a lot, I´m testing it right now with the wingtips.
I don’t know how I can add a second height range modifier, I´ll try again tomorrow.
Add first one, then click on Layers and next to height levels are two buttons - “-” and “+”. Click on “+” and specify heights. Modifiers can’t overlap.
