I would like to get my 3d prints to come up as solids, no matter how slow. I virtually tried every single option slic3r offers and there are still meshes inside. I would like to get rid of all meshes and outputted a solid plastic brick infilled in a way that there are no empty spaces inside. Just like when edges are generated.
100% infill. The layer view won't look solid because it doesn't depict the thickness of the extrusion, but it will be (or close, depending on other settings).
Supported patterns at 100% are rectilinear, concentric, hilbert curve, Archimedean chords, and octagram spiral.
For solid infill you must ensure that you are not over-extruding by even a small amount otherwise your print will gradually get bumpier and bumpier until it fails - with solid infill any over-extrusion has nowhere to go except up and each layer will get worse, especially near the perimeters where extruder lag often causes a small section of over-extrusion. It is usually best to use 90% or 95% rectilinear infill to avoid that possibility - which still produces a pretty solid print.
You can also set the number of top & bottom solid layers (horizontal shells) to be equal or higher than half the total number of layers of your print.
