Solved Need Slicing Help

[flyingkelpie]

I've got an Ender 3 V2 and it's been printing really well but I have been having issues with the slicer. I'm trying to slice this...

And I've been getting this...

So if someone could guide me through the process of slicing an aerofoil shell type thing it would be helpful.

your wall thickness in your model is to small for the slicing method.

looking at what your trying to print, I suspect you want to make a solid model, set it to not top/bottom layers, no infill, 1 wall thickness.

Thanks that fixed a few problems. Unfortunately there is still nothing between the top and bottom for some reason. Is there a problem with this happing or will it print alright?

I've seen something like this is when the object dimensions are to big for the build plate when trying to set up for slicing. First pic there's no brim/skirt and fits within the build plate dimensions, second pic now has brim/skirt and now (possibly) to large for your printer bed dimensions within the slicer, so now the slicer has grayed it out.

can you link your stl file your working with? I can load it up in my slicer and get some ideas on what might be the issue

 

[JasonK]

that also isn't going to print - at least not without supports. you have a huge bridge - that is curved - I doubt any printer is going to pull off a curved bridge like that with a single layer thick walls and have it look good.

 

[JasonK]

where did you get that airfoil shape from?
did you make it?
did you download it from somewhere?

Nah its for a school project.

True I didn't think about that.

did you design it then?

 

[JasonK]

your surfaces have 0 thickness, you need to apply a solidify/thickness modifier to give it thickness to the surfaces.

This is after I gave the surfaces a non-zero thickness:


I took your STL, loaded it in blender, applied the Solidify modifier with 0.2m thickness (this appears to have made the walls thick enough for the slicer to make them 1 wall thick, but not try to make them 2 walls thick), then re-exported it. there does look like there area few issues/unexpected holes.

So if you make your walls the same thickness as your nozzle size, it should slice up nicely for you.

 

[JasonK]

if you want/need that hole, either print it in 2 parts that key together or you will need to use supports.

 

[tamuct01]

Yes, the top part of that hole will be a large bridge. It's nearly impossible for a FDM printer to do a curved bridge line like that. Supports on something like this will likely be difficult to remove and probably have as much filament in them as the rest of the piece. You can also emboss the surface with the cutaway space and print it solid and cut it out later.

Okey I'll print that as a prototype as this is only the prototype version then work on a batt hatch

0 minutes?

I've decided I will use supports but I'm not sure why its saying it will print for 0 minutes.

go to the preview. looks like it didn't slice anything. my settings might be slightly different then your, making it slice it, but yours not doing so.

 

[flyingkelpie]

 

[JasonK]

you must have a setting slightly different then me.

here is the solidify with 0.4 thickness instead of 0.2 - which I did the first time. make sure your slicing settings are all default and see what happens. if that doesn't get it working for you, your going to need to figure out how to do a solidify operation in what ever tool your using.

That worked, Thanks for all the help!
