1、演讲题目：3D Printing Technology小组成员：解 宇 王保群 王金豹 杜英豪 谢子毅 熊建飞颜实 颜培梁 1、Introduction to 3D Printing 2、History of 3D Printing4、Current 3D Printing Technologies 5、Some problems of 3D printing6、3D Printing Capabilities3、Manufacturing A Model With The 3D Printer3D printing is a form of additive manufacturing te
2、chnology where a three dimensional object is created by laying down successive layers of material. It is also known as rapid prototyping, is a mechanized method whereby 3D objects are quickly made on a reasonably sized machine connected to a computer containing blueprints for the object.三维印刷是一种通过铺设材
3、料的连续层创建 三维对象的添加剂制造技术。它也被成为快 速原型制造。这是一种机械化的方法，3D对 象通过一个包含着打印对象蓝图的计算机连 接的有合理尺寸大小的机器而被快速制造。This revolutionary method for creating 3D models with the use of inkjet technology saves time and cost by eliminating the need to design; print and glue together separate model parts. Now, you can create a comple
4、te model in a single process using 3D printing. The basic principles include materials cartridges, flexibility of output, and translation of code into a visible pattern.这一革命性的建立三维模型的方法通过喷墨 技术的使用消除了需要设计印刷和粘合单独 部件模型的麻烦，节约了时间和花费。现在 ，你可以在一个单独进程中创建一个使用三 维打印的完整模型。这个基本的原则包括材 料墨盒，灵活的输出和代码能进入一个可用 的模式。The tec
5、hnology for printing physical 3D objects from digital data was first developed by Charles Hull in 1984. He named the technique as Stereo lithography and obtained a patent for the technique in 1986.该技术用于打印来自物理数据的3D物体最 早是由查尔斯赫尔在1984年开发的，他命名 该技术为光固化并于1986年获得了技术专利。In 1993, Massachusetts Institute of Tec
6、hnology (MIT) patented another technology, named “3 Dimensional Printing techniques“, which is similar to the inkjet technology used in 2D Printers. In 1996, three major products, “Genisys“ from Stratasys, “Actua 2100“ from 3D Systems and “Z402“ from Z Corporation, were introduced.1993年，美国麻省理工学院（ MI
7、T）获得专利的另一项技术，一 个名为“三维印刷技术”，这是类似 于2D打印机采用的喷墨技术 1996年，三大系列产品， Stratasys公司的“Genisys”，3D系 统的“ACTUA2100”和Z公司的 “Z402”被推出。In 2005, Z Corp. launched a breakthrough product, named Spectrum Z510, which was the first high definition color 3D Printer in the market. Another breakthrough in 3D Printing occurred i
8、n 2006 with the initiation of an open source project, named Reprap, which was aimed at developing a self replicating 3D printer.2005年，Z公司推出突破性的产品， 名为频谱Z510，这是市场上首款高 清彩色三维打印机. 在3D打印的又一次突破发生在2006 年的一个命名的RepRap开源项目的 启动，其目的是开发一种自我复制的 3D打印机。The model to be manufactured is built up a layer at a time. A la
9、yer of powder is automatically deposited in the model tray. The print head then applies resin in the shape of the model. The layer dries solid almost immediately. The model tray then moves down the distance of a layer and another layer of powder is deposited in position, in the model tray. The print
10、 head again applies resin in the shape of the model, binding it to the first layer. This sequence occurs one layer at a time until the model is complete.这个模型被一层一层的制造，当某一层打印用的 粉末被放到模型托盘上时，打印头就会把这些合 成树脂涂在模型上，然后这一层立刻就会变干成 为固体物质。该模型托盘向下移动一层并且打印 另一层所要的粉末会被放在合适的位置，打印头 重新把这些合成树脂涂在模型上，并覆盖掉前一 层；按照这种顺序一次打印一层直
11、到该模型被完 全打印出来。Engineers at the University of Southampton in the UK have designed, printed, and sent skyward the worlds first aircraft manufactured almost entirely via 3-D printing technology. The UAV dubbed SULSA is powered by an electric motor .its wings hatches and control surfaces basically everyt
12、hing that makes up its structure and aerodynamic controls was custom printed to snap together. It requires no fasteners and no tools to assemble。英国南安普敦大学的工程师 已经设计、打印、向天空发 送了第一台几乎全部是用3- D打印技术生产的飞机。这 个被称为SULSA的无人机是 由电动马达提供动力，它的 机翼舱口和控制面以及构成 它的结构和气动控制一切东 西，都是先自定义打印出来 ，然后组成在一起的。它无 需扣件，也不需要用工具来 组装。 Stere
13、o lithography - Stereo lithographic 3D printers (known as SLAs or stereo lithography apparatus) position a perforated platform just below the surface of a vat of liquid photo curable polymer. A UV laser beam then traces the first slice of an object on the surface of this liquid, causing a very thin
14、layer of photopolymer to harden. The perforated platform is then lowered very slightly and another slice is traced out and hardened by the laser. Another slice is then created, and then another, until a complete object has been printed.立体光刻-光固化3D打印机（被称为斜线或立体光刻设备）在一 大桶液态光固聚合物表面下安放了一个多孔的平台。紫外激光束 然后跟踪此
15、液体表面上的对象的第一切片，从而导致很薄的一层 光敏聚合物变硬的。穿孔的平台很轻微的降低，然后另一片被激 光追踪出来并使其硬化。另一片被制造，然后是下一片，直到一 个完整的对象被打印出来。The VFlash printer, manufactured by Canon, is low-cost 3D printer. Its known to build layers with a light-curable film. Unlike other printers, the VFlash builds its parts from the top down.VFlash打印机，由佳能公司制造
16、的，是低成本的三维打印机。 据了解，以构建层具有光固化性膜。不同于其他打印机，该机型 建立零件模型顺序从上往下。Desktop Factory is a startup launched by the Idealab incubator in Pasadena, California.Fabhome, an experimental project based at Cornell University, uses a syringe to deposit material in a manner similar to FDM. The inexpensive syringe makes it easy to experiment with different mate
