The Economist magazine had commented: "inventions can bring influence, at that age are difficult to predict, 1750 steam engine so, 1450 printing so, transistors in 1950, too. Now, we still can not predict, 3D printing will be in a long time how to change the world."

3D打印技术简介 PPT
4、全彩色打印机
• 这里说的彩色可不是几个简单的颜色没有过度混合起来。能否支持彩色打印还是需要看 3D 打印机所采用的技术是否在打印过程中给材料进行染色或者混色。
• 目前实现彩色打印主要两种方式 • 采用的 3D 打印技术是否有条件在打印过程中给材料染色。 • 采用的 3D 打印技术是否支持多种耗材，不同颜色的耗材在打印的时候进行混色。
❖ 3、快速成型系统的组成
快速成型系统是下面若干 先进技术集成的。
（1）计算机辅助设计(CAD) （2）计算机辅助制造(CAM) （3）计算机数字控制(CNC) （4）激光 （5）精密伺服驱动 （6）新材料

关于3D打印机
3D打印机的类型
• 目前国内还没有一个明确的 3D 打印机分类标准，但是我们可以根据设备的 市场定位将它简单的分成三类：个人级、专业级、工业级。
• 它是一种以 3D 设计模型文件为基础，运用不同的打印技术、方式使 特定的材料，通过逐层堆叠、叠加的方式来制造物体的技术。
• 2、快速成型技术产生的背景—全球制造战略的变迁
全球制造业企业的整体发展战略已经从上世纪60年代“如何做的更 多”、70年代“如何做的更便宜”、80年代“如何做的更好”发展到90 年代的“如何做的更快”。
• 设备打印材料都以 ABS 塑料或者 PLA塑料为主。 主要 满足个人用户生活中的使用要求，因此各项技术指标都 并不突出，优点在于体积小巧，性价比高。
2、专业级3D打印机
• 专业级的3D打印机，可供选择的成型技术和耗材 （塑料、尼龙、光敏树脂、高分子、金属粉末等） 就要比个人 3D 打印机要丰富很多。设备结构和技 术原理相比起来更先进自动化更高，应用软件的功 能以及设备的稳定性也是个人3D打印机望尘莫及。 这类设备售价都在十几万至上百万人民币。
3D打印介绍ppt课件
在产品开发与设计过程中，由于设计手段和其他方面的限制，每一 项设计都可能存在着一些人为的设计缺陷。如果未能及早发现，就会影 响后续工作，造成不必要的损失，甚至会导致整个设计的失败。使用快 速成型制造技术可以将这种人为的影响减少到最低限度。快速成型制造 技术由于成型时间短、精度高，可以在设计的同时制造高精度的模型， 使设计者能够在设计阶段对产品的整体或局部进行装配和综合评价，从 而发现设计上的缺陷与不合理因素，改进设计。
进行装配校核、干涉检查等对新产品开发，尤其是在有限空间内的 复杂、昂贵系统（如卫星、导弹）的可制造性和可装配性检验尤为重要。
如果一个产品的零件多而且复杂就需要做总体装配校核。在投产之 前，先用快速成型制造技术制作出全部零件原型，进行试安装，验证设 计的合理性和安装工艺与装配要求，若发现有缺陷，便可以迅速、方便 地进行纠正，使所有问题在投产之前得到解决。下图为某发动机气缸部 件中气缸盖改进设计后制作的用于装配检验的LOM模型。

3、工业级3D打印机
? 工业级的设备除了要满足材料上面的特殊性，制造大尺寸的物件等要求。更关键是物品制造后它需 要符合一些列的特殊应用的标准，因为这类设备制造出来的物体是直接应用的。
? 比如飞机制造中用到的钛合金材料，就需要对物件的刚性、任性、强度等等参数有一系列的要求。 由于很多设备是根据需求定制的因此价格很难估量了。

累积技术
熔融沉积式 (FDM）(FDM） 电子束自由成形制造(EBF)(EBF) 直接金属激光烧结（DMLS）DMLS） 电子束熔化成型（EBM）EBM） 选择性激光熔化成型(SLM)(SLM) 选择性热烧结（SHS）SHS） 选择性激光烧结（SLS）SLS）
• 优点：比SLA要结实的多，通常可以用来制作结构功能件；激光束选择性地熔合粉 末材料：尼龙、弹性体、未来还有金属；优于SLA的地方：材料多样且性能接近普 通工程塑料材料；无碾压步骤因此Z向的精度不容易保证好；工艺简单，不需要碾压 和掩模步骤；使用热塑性塑料材料可以制作活动铰链之类的零件；成型件表面多粉 多孔，使用密封剂可以改善并强化零件；使用刷或吹的方法可以轻易地除去原型件 上未烧结的粉末材料 。

3D Printer History
• 3D printing concept as early as a few decades ago has been proposed. In the 1970s, with the rise of 3D aided design, designers can see virtual 3D objects in computer software, but to these objects in clay, wood, or is made out of metal model is very difficult, can use time-consuming cost money to describe. 3D printing, so that the plane into a three-dimensional process a lot simpler, designer of any changes can be in after a few hours or overnight to re print it out, rather than spend a few weeks time factory put the new model manufactured. Only in this way can greatly shorten the production cycle, reduce the production cost. And with the continuous progress of science and technology, more materials are printed out, it was discovered that the original can also be so play.

• The upper part of the machine is a translucent cover, a row of the control button next to a computer. A cover, left standing four boxes of different colors of ink, on the right side of the work area put gypsum fine grinding powder. The work, the powder will be a layer of liquid connection is also a special glue, in accordance with the different cross sectional pattern curing, one layer upon layer, feel like a cake to create three-dimensional enry

3D printers are not your average printer They bear little resemblance to today's
document or photo printers, They can build objects from scratch—or
It builds up a 3D model one layer at a time, from the bottom upward, by repeatedly printing over the same area.
3
The printer creates a model over a period of hours by turning a 3D CAD drawing into lots of two-dimensional （二维）, cross-sectional layers
Designed by scientists at Germans' Fraunhofer Institute

The technique involves printing artificial biological molecules with a 3D inkjet printer, and then zapping the those molecules with a laser that forms the material into the shape of blood vessels. Like real blood vessels, the artificial vessels have two layers and can form complex branching stly need to print in 3D with plastic: in theory, you can print objects using any molten material that hardens and sets reasonably quickly
Most 3D printers essentially works by extruding molten thermoplastics (mostly ABS) through a tiny nozzle that it moves around precisely under computer control.
rather, from a CAD or 3D scanner file— out of a variety of materials.
