Course Outline 课程大纲

This course consists of 6 modules that focus on Desktop 3d printing hardware.
这门课程包含 6 个模块，专注于桌面 3D 打印硬件。

Module 1: Course Orientation & Module 1 Origins of Desktop 3D Printing 模块 1：课程介绍 & 模块 1 桌面 3D 打印的起源

In this welcome module, you will become familiar with the course, your classmates, and our learning environment. In module 1, you will learn about “desktop” 3D printing as opposed to any other sort of 3D printing. You’ll learn this and more by exploring the history behind the creation of desktop 3D printers, overviews of the different types of desktop 3D printers, expose a few of the common misconceptions about them, and explore where you might gain access to them for yourself, including details to help you make an informed decision about the class of desktop 3D printer hardware that suits your specific needs and budget.
在这个欢迎模块中，您将熟悉课程、同学以及我们的学习环境。在模块 1 中，您将了解“桌面”3D 打印，而不是其他类型的 3D 打印。您将通过探索桌面 3D 打印机背后的历史、不同类型桌面 3D 打印机的概述、揭示一些关于它们的常见误解，以及探索您可能如何获得自己的桌面 3D 打印机，包括帮助您做出明智决定的具体细节，来学习这些内容以及更多。

Module 2: Exploring Desktop 3D Printing Hardware - Control and Mechanical Systems 模块 2：探索桌面 3D 打印硬件 - 控制与机械系统

From a distance, the process of 3D printing looks like magic. Step closer and see how all of the core systems and components work together to fabricate real physical objects from digital design files. We make our first of two excursions “under the hood“ to look at the core systems and components that together and in parallel bring function to 3D printers.
从远处看，3D 打印的过程就像魔法。走近一点，看看所有核心系统和组件是如何协同工作，将数字设计文件制造出真实的物理对象。我们进行了两次考察中的第一次“引擎盖下”之旅，来观察那些共同且并行地为 3D 打印机带来功能的内核系统和组件。

Module 3: Exploring Desktop 3D Printing Hardware: Materials and Extrusion System 模块 3：探索桌面 3D 打印硬件：材料和挤出系统

Now that we have an understanding of the controls and motion system. Let’s take a closer look at the extrusion process and what makes 3D printer filament so special. Let’s learn about the materials and processing that they go through when being printed.
现在我们已经了解了控制和运动系统。让我们更深入地看看挤出过程以及 3D 打印机丝材的独特之处。让我们了解它们在打印过程中所经历的材质和处理方式。

Module 4: Preparing Designs and Jobs for Desktop 3D Printing & Printing Services 模块 4：准备桌面 3D 打印及打印服务的设计和作业

Now that you have looked closely at the fundamental physical systems and components involved with how desktop 3D printers function, and how they can be operated in “normal” situations, it is time to explore the processes involved with preparing digital objects and creating the job files (G-Code, or variant) that will drive the fabrication process.
现在你已经仔细研究了桌面 3D 打印机工作原理中涉及的基本物理系统和组件，以及它们在“正常”情况下的操作方式，是时候探索准备数字对象和创建驱动制造过程的作业文件（G-Code 或变体）所涉及的过程了。

Module 5: Operating Desktop 3D Printer Hardware: Preparing to Print 模块 5：操作桌面 3D 打印机硬件：打印准备

Okay, you’ve taken a broad view of desktop machines in the context of the history of 3D printers, very close view of the specific components and systems underneath the hood, and have crossed back-and-forth across the virtual-physical divide -- now it is time to spend some time seeing what it is like to use them!
好的，你从 3D 打印机历史的背景下对桌面机进行了宏观审视，对引擎盖下的具体组件和系统进行了微观观察，并在虚拟与物理之间来回穿梭——现在，是时候花些时间体验一下使用它们的感觉了！

Module 6: Operating Desktop 3D Printer Hardware: Printing and What Follows 模块 6：操作桌面 3D 打印机硬件：打印及后续操作

In the final module we will then wrap up our exploration of operating desktop 3D printing hardware, covering the moment you hit print to fabricate a part, through to the stages that follow. We’ll wrap up the course with a section highlighting approaches to technical support, troubleshooting, and preventative maintenance, as long as some recommendations for common tools, mods, and add-ons we hope to help you on your own 3D printer experiences that will follow.
在最后一模块，我们将总结对桌面 3D 打印硬件的探索，从点击打印以制造零件的那一刻开始，到后续的阶段。我们将通过一个强调技术支持、故障排除和预防性维护方法的章节来结束课程，同时也会提供一些常见工具、改装和附加组件的推荐，希望这能帮助你在接下来的 3D 打印机体验中。
