打印，通常指把电脑或其他电子设备中的文字或图片等可见数据，通过打印机等输出在纸张等记录物上。
扫描，指通过电子束、无线电波等的左右移动在屏幕上显示出画面或图形。
Printing usually refers to outputting visible data such as text or pictures in a computer or other electronic device on a record such as paper through a printer.
Scanning refers to displaying pictures or graphics on the screen through the left and right movement of electron beams, radio waves, etc.
3D打印技术
3D打印技术，又称增材制造，这个被誉为“上上个世纪的思想，上个世纪的技术，这个世纪的市场”的奇葩不仅可以打印出电影中所需要的道具，只要有足够的材料配以严密的数据，大到路桥别墅，小到厨房用品都可以通过它来实现。
扫描的几种含义
1、诊断图像是指利用一起先进设备，绘制出人体内部的图像，它能帮助医生诊断病情。
2、许多图像技术都叫做扫描，因为他们都是用一束光线围绕着人体进行扫描。
3、CT扫描是利用一束X射线，围绕着缓慢向前移动的病人不停旋转，以获得一系列不
同切面的图片。
4、CT是计算机X射线断层造影术的简称。
5、MRI扫描是将病人至于一个强磁场中，使病人体内的质子全部转变成同一种类型。再
用无限电脉冲来来回回撞击这些质子，通过一台扫描机接收发射出的无线电信号，并
转化为电子图像。
3D printing technology
3D printing technology, also known as additive manufacturing, this wonder known as “the ideas of the last century, the technology of the last century, and the market of this century” can not only print out the props needed in the movie, as long as there are enough Materials are matched with strict data, and everything from road and bridge villas to kitchen supplies can be realized through it.
Several meanings of scanning
1. Diagnostic images refer to the use of advanced equipment to draw images of the inside of the human body, which can help doctors diagnose conditions.
2. Many imaging technologies are called scanning because they use a beam of light to scan around the human body.
3. CT scan uses a beam of X-rays to continuously rotate around the slowly moving patient to obtain a series of different images.
Pictures of the same section.
4. CT is the abbreviation of computed X-ray tomography.
5. MRI scanning places the patient in a strong magnetic field, which converts all the protons in the patient’s body into the same type. Again
The protons are hit back and forth with infinite electric pulses, and the emitted radio signals are picked up by a scanner and
converted into electronic images.
