I have seen videos or heard about 3D printed buildings, 3D printed space shuttle parts and more. There seems to be a lot of craze developing around 3D printed manufacturing.
I have never heard anyone discuss stress analysis of 3D printed parts. I have seen in the past that 3D printed plastic parts were rather fragile. However, it is possible that they were manufactured using the most coarse and cheap settings since they were just models of certain concepts.
Since we are moving to manufacture more and more things through 3D printers, has anyone done research into stress analysis on 3D printed mechanical parts?
