I'm trying to print a model and its supposed to be solid. When I slice it, it makes it hollow. If I turn the model say 90 degrees, it slices it differently. More solid, but still some hollow parts. Whats going on with this? I just wasted so much pla. Need to get in the habit of checking layer by layer before printing. See attached photos
What its supposed to be
Oriented at 0 degrees
Oriented at 90 degrees (looks like it should, but on other side is empty space, didn't realize before I took the picture)
Webcam photo, can see its hollow on the side (at work right now)
