Q A Good afternoon, everyone! My name is, majoring chemistry in PHD. Before I introduce today’s contents. Let’s see the drawings first. Look at this and this. * * 3D printers are great for complex engineering projects, but what happens when you try to get creative with it? Most artists obsessed with digital fabrication opt for milling machines or laser etching–which are cheaper and easier to access–but some have stuck with rapid prototyping (aka rapid manufacturing) because building ultra-precise objects out of nothing is undeniably awesome. Karsten Schmidt mashed up typography, MRI scans, and 3D printing to make this art for Print Magazine’s cover story about kinetic typography. Figure 1. Plane models generated by NYUs Spectrum Z510 3D printer. Figure 2. Detail of a model that takes advantage of the Spectrum Z510s color printing capabilities. Do you fancy them? Yeah~ They are products made by the 3D print technology.I divide four parts of the topic, which are basic principle, advantages, applications and challenges separately. * * * * * * What is 3D print? It is a mechanized method whereby three dimensional objects are quickly made on a reasonably sized machine connected to a computer containing blueprints for the objects. * * Software slices CAD file into thousands of thin layers 软件将文件分割为适于三维打印成型机使用的薄截面片 Physical model is built one layer at a time 这样每次一层，逐渐创建模型 Ink-jet print heads deposit binder into powder to create layers 喷墨机打印头放置黏合剂入粉末创造层数 To make it easy for understanding, we could use four steps to describe the process. Firstly, spread a layer of powder; secondly, print a slice of the part; thirdly, spread another layer of powder; at last, parts are printed to be a 3D object. * * A 3D Printer is an Output Device for 3D CAD Data. There are four kinds of 3D Printer currently, as shown in the pictures. * * This revolutionary method for creating 3D models * * with the use of ink-jet technology saves time, manpower and cost by eliminating the need to mo
