3D打印技术-英文版
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 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.

A new technique has been created that prints out artificial blood cells

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

6Hale Waihona Puke 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 structures.

3、选择性激光烧结(简称SLS) SLS工艺又称为选择性激光烧结，由美国德克萨斯大
学奥斯汀分校的C.R. Dechard于1989年研制成功。SLS工 艺是利用粉末状材料成形的。将材料粉末铺洒在已成形零 件的上表面，并刮平；用高强度的CO2激光器在刚铺的新 层上扫描出零件截面；材料粉末在高强度的激光照射下被 烧结在一起，得到零件的截面，并与下面已成形的部分粘 接；当一层截面烧结完后，铺上新的一层材料粉末，选择 地烧结下层截面。

这让制造变得更简单。Kor只要将模型的每部分上传到打 印机上，2500小时后，他就拿到了所有的塑料部件，然后 他再把这些东西组装在一起。完整的Urbee看上去像是一 个大号电脑鼠标。
Urbee的打印材料大部分是塑料，当然，它的地盘和 引擎还是钢铁。这车开到路上安全吗？Kor的答案是肯定 的，“我们甚至觉得它可以用于专业比赛的赛车”，他告 诉《连线》杂志，“我们要让这辆车通过美国勒芒比赛的 技术检测

What is 3D printing
• 3D printing, also known as additive manufacturing, is a technology that uses computer-aided design (CAD) to create three-dimensional objects. It involves depositing or spraying materials layer by layer based on the design to create complex shapes and structures.
Applications of 3D printing
• It is commonly used for prototyping and short-run manufacturing, but its use is constantly expanding to oing
Applications of 3D printing
• 3D printing has a wide range of applications across various industries such as healthcare, automotive, aerospace, architecture, and consumer goods.
