Module 5 Overview模块 5 概述

Overview 概述

In previous modules, we reviewed the context within which the special category of “desktop” 3D printers emerged and did a deep dive into each of the core components of our example desktop 3D printer equipment. Now it is time to undertake the first part of our exploration of operating desktop 3D printing equipment, from unboxing and onboarding, to calibration/maintenance, to basic operations stages, to preparing your materials.  
在之前的模块中，我们回顾了“桌面”3D 打印机这一特殊类别出现的背景，并深入探讨了我们所举的桌面 3D 打印机设备的每个核心组件。现在，是时候开始探索操作桌面 3D 打印设备的第一部分了，从开箱和安装，到校准/维护，到基本操作阶段，再到准备你的材料。
