【Optical Design Considerations for Additive Manufacturing】Additive manufacturing (also known as 3D printing) has been around since the early 1980s, with the first technologies using ultra-violet sources as an optics-based approach to solidify polymer resins. Over the decades, new technologies have enabled creation of functional parts using a wide variety of polymers, powders and even metals. The use of 3D printing has grown exponentially across multiple industries, none more so than medical, where multiple applications have benefitted from the ability to rapidly manufacture custom orthopedic implants for knee and hip replacement surgeries. Dentistry is one of the largest adopters of 3D printing where it is used to create highly tailored crowns, bridges, and aligners found in orthodontics.More information:https://t.cn/A66ZuuiW

有小可爱私信我拍娃娃用什么相机比较好，顺道我出来分享一下~[泪]大家随意康康就行，我不是专业的。

我用的相机比较普通，单反入门机子，以前上大学的时候，学校要求统一买的。用得比较旧了，我没有专门学过摄影，大学的摄影课也比较水。我单反的型号是佳能EOS760D，镜头是18-200mm is。

镜头是变焦的，近景远景都能拍，能一镜到底。但是也有缺点，就是景深不够完美，拍大场景的话需要后期拉一下虚化背景。大场景拍娃娃，脸部可能没那么高清。

拍大头、半身照、小场景、小物件的话，还是挺够用的了。[泪][跪了]我也不追求一些很牛的大片……

记住，满足自己的需求是最重要的，要搞清楚这个机子用在哪里，而不是一味追求高配。现在很多优秀的微单也横空出世，可以多问问一些拍片太太，多做参考，对比一下。

祝各位都能拍出自己满意的效果！[抱一抱][抱一抱]
