✅ - Inside of Mesh shows support material instead of infill

[serene ore]

I'm printing the backplate of my iron man suit. When going through the stl file to make sure everything will print right i noticed during these layers, instead of having infill, the inside of this part is filled with supports. the top will get covered later in the print but im afraid this will make this portion of the print weak. is there a way i can edit this so that infill is used? i do have blender but dont know how to edit stl files yet. pretty sure a quick youtube video would help with that though. all in all this is a small portion of the back so it shouldnt be too much of a problem. but with moving parts thats gonna be around it i just want the least amount of problems

I'm thinking the reason why the slicer sees it as open space is perhaps because the mesh isn't closed or watertight...

What do the first few layers of the object look like where that internal cavity starts and where the support is in the bottom?

Also, I don't think the object will be any weaker really; you already have a good chunk of walls and infill surrounding it... I would, however, suggest switching to Ultimaker Cura or Orca Slicer over using Creality Slicer, especially for an important piece such as this. You'll get better control over the supports, walls, and infill, especially if you use Orca. Plus, you can tell Orca to fix the mesh, and it will automatically take care of small holes and other tiny printing issues you wouldn't normally catch.

this is the layers beginning of where the cavity starts

Hm. Yeah, it's just treating it as an external wall, so it assumes it needs support inside. Use Orca Slicer, load the object, and right click to the "fix" option. It might give you different results.

Also, you could potentially get away with using three walls and just ignoring the supports... They'll just stay permanently inside.

More walls = more strength. I also think that triangle infill might work a bit better than gyroid; it's a bit faster and not as difficult for the printer. What printer you using?

i have the ender max 3 neo. i'll download orca now and come back with the results

[karmic musk]

Ok. Use the Ender 3 V2 profile and adjust the build volume to 300x300mm bed with 320mm z-height. That's what I use for my Ender 3 Max Neo.

so i played around with Orca for a bit, the fix function didnt fix the supports not being infill. I'm not gonna worry about it though. I was just thinking that since it'll have moving parts it might be weaker than intended but it still looks pretty good

[karmic musk]

Ok, sounds good!

If you really wanted, I could maybe take a look at the file and see if I can force it to go to infill... I've got a little knowledge about Fusion 360 and some other software that could let me possibly get it to do what you want it to do. Plus, now it's bothering me that this seems "unfixable"...

[serene ore]

sure ill dm it to you

[karmic musk]

Ok
