I am 3D printing half of the bottom section of the outside shell assembly of an all-in-one case mold (to make a plaster mold for casting pottery). There are multiple factors to take into account to make this print quickly with minimum material and yet be strong.
In a 3D print, a small amount of infill can greatly outweigh the generation of a large amount of printed support. This can greatly reduce print time and filament consumption (this is printed with 0.8mm thick walls).
Far left: The green part is the support my slicer has generated in order to hold up the flat top flange. This is not only a waste but problems are likely with adhesion on the lower support sections where tiny points are printed on the steeply included surface to start each.
Middle: The same piece has been edited to terminate at the top with a triangular cross section. This is a 40 degree angle (as can be seen on the far right) - the slicer has been configured with an overhang threshold of 39 degrees, that means it does not need to generate support. It does infill that section, but the increase in time is minimal.

Infill and Support
Infill and support are structural elements that 3D slicer software uses (e.g. to fill the interior of solid parts or support contours over empty space) |
