Printing solid

“

- [Speaker 1] A 3D print generally consists of solid surfaces. They're around one millimeter thick, but the interior filled with sparser infrastructures. The infill density is the percentage of the interior space of the print that you want to fill. And it's typically set somewhere in the area of 20%. This saves time and material compared to a solid print. It makes printed parts light while providing a significant portion of the strength of a solid part. With only minimal bracing from the infill, the surfaces provide most of the strengths of the print. So doubling the infill density will usually not have a big effect on strengths. In many cases, it's actually possible to print with no infill so that the object is completely hollow. Providing strength is only a secondary purpose of infill. The primary purpose of infill is to act as a support structure for the internal overhangs near the top of a print. If you're printing…
