Real Engineering explains the materials science behind metal 3D printing, including crystal structure, laser sintering, and why printed parts develop fatigue cracks. It shows how process imperfections limit the strength of printed metal.
Why HN recommends it: Commenters point to it whenever 3D-printed metal parts come up, as a clear explanation of why they have poor fatigue life and material defects.
