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 nter 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.

• Fotokopieën van objecten 3d-scanning technieken
• Nieuwe materialen voedingsmiddelen, lichaamsdelen, etc
Toekomst
• 3d-printing betekent revolutie voor product-design sieraden, accessoires, decoratie voor huis en tuin etc.
• Open source van fysieke items - van elektronen naar atomen - vergelijk de energie en de kracht van de open-source beweging in software
Belangrijke trends
Productontwikkeling
• Van rapid prototyping naar nieuwe productie • Prototypes kosten niets meer • Veel experimenteren mogelijk voordat je tot het beste product komt
• Betaalbaar voor consumenten: goedkopere printers voor thuis (Bijenkorf, Ultimaker, Cubify) • Laagdrempelig, eenvoudige beschikbaarheid van ontwerpsoftware (Google Sketchup) • Persoonlijk, personaliseerbare producten (bijv. telefoonhoesjes, ringen) • Technologische vooruitgang, zowel in printtechnieken als in materialen en afwerking (metalen, keramiek, kunststoffen) • Creatief, een voorhoede van ontwerpers ziet in 3d-printing een nieuwe creatieve uitlaatklep

3D打印主流技术
? 3D打印的技术主要包括SLA、FDM、SLS、LOM等工艺， 下面我们简单介绍三种主流技术：
? 1、立体光刻造型技术(SLA)：大家可以想象一下把一根黄 瓜切成很薄的薄片再拼成一整根。先由软件把3D的数字模 型，“切”成若干个平面，这就形成了很多个剖面，在工 作的时候，有一个可以举升的平台，这个平台周围有一个 液体槽，槽里面充满了可以紫外线照射固化的液体，紫外 线激光会从底层做起，固化最底层的，然后平台下移，固 化下一层，如此往复，直到最终成型。
