Three-dimensional printer is made up by a baseplate, a plastic rod, a print head, a temperature controller, a large tank and compressor,and a computer.

先简单概述下3D打印机的组成部分.还不够完整.

修改:Three-dimensional printer is made up of  a computer , a baseplate, a print head and nozzle, a plastic rod, a thermocouple, a temperature controller,and a large tank and compressor.

When the printer was started, it is operated from the computer. The model is printed on the baseplate that moves in the horizontal directions, while the print head and nozzle move in the vertical direction. The raw meterial comes from the plastic rod which is using compressed air from the large tank and compressor and melted by the print head which is regulated by electrical heat sensor connected to a temperature controller. Each time it builds up one layer and again until the plastic is dry. And through repatedly printing over the same area from the bottom upward, a 3D is done.

叙述打印机打印模型的完整过程，此为主线，副线则要包括打印机硬件再现.

修改:The whole printing process is operated from the most important component-computer and it knows which things you want to print. After we give order to the computer, the printer is exactly started. With thermocouple and temperature controller set, the large cylinder tank and compressor deliver the compressed air into the plastic rod to push the raw meterial-ABS plastic to the printer head.For ABS plastic can be sanded smooth or painted and is easy-melted inside the printer but hard-melted outside, it is the best choice for 3D printers.The body connected the printer head is installed on the railway which consists of two robs in order to move regularly.And the nozzle goes through the hole digged on the printer's body.The printer head and nozzle move in the vertical direction to build up the model on the baseplate one layer at a time，from the bottom upward, by repeatedly printing over the same area,and a model is done！

图给的是很早以前的打印机，写着写着发现自己的思路是跟着视频里的走。。。
