PickVidsThe Material Science of Metal 3D Printing
推荐理由
Great Real Engineering video with a lot of discussion of the issues with material properties, crystalline structure, and fatigue cracks
说明
这是2019年由Real Engineering发布的一部讲解，主题归在Materials science。它讲的是metal 3d printing materials这一支里的具体问题，而不是把整个领域扫一遍。适合按兴趣直接看、不打算先补课的人。内容上可以概括成：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.这些读者给出的理由，核心是：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.讲法不绑某一条新闻，过几年仍然可以当材料看。从2019年到2024年，有3位不同的读者在2个不同月份把它推荐出来，其中明确叫别人去看的有0次。适合用一集把一个概念补上的人。抓住它用的那个图像或类比，比背公式重要。如果已经会了基本定义，就把注意力放在它怎么把metal 3d printing materials变成能跟着复述的例子。
