Structural improvements in 3D printing

thingiverse

In numerous situations, we require amplified fortification of the 3D printed details in specific locales - for instance, incorporating some pivot points, screws, etc. Normally, the 3D printer evenly fills the internal space with some pattern (hexagonal, squares, etc.) and there is no way to increase the density of the pattern or create more solid structures inside the body only for the places which demand greater strength. Here I'm revealing a method of enhancing the 3D printed details strength by adding internal frameworks inside the body. At the end of the 3D printing process, the details appear the same from the outside, but for some areas the strength is significantly increased. The concept is that if we create very narrow voids inside the body (gap under 0.05mm) they compel the 3D printing slicer to add shells around these areas and as the shell lines are so close they merge together into solid ribs.
