清华大学激光快速成形中心林峰教授揭开3D打印神秘面纱在清华大学林峰教授的办公室里,到处都是逼真的3D打印实物模型,手机外壳、工业零件、医疗支架、各种玩具……甚至名片盒都是3D打印的,红色的水立方形状,煞是好看,用手一摸,还有纹路感。他指了一下桌子上与普通打印机差不多大小的设备,对本刊记者说:这些物品都是这台3D打印机做出来的,它采用熔融挤压快速成形技术,把塑料加热到200多度,然后用喷头一点点挤出来,进行堆积制造。这台3D打印机国内卖一万元人民币,美国卖1500美元,它甚至都能把活体细胞打印出来。
Professor Lin Feng, Laser Rapid Prototyping Center, Tsinghua University Unveils the Mystery of 3D Printing In the office of Professor Lin Feng of Tsinghua University, vivid 3D printed physical models, cell phone cases, industrial parts, medical supports, various toys ... and even business card cases Are 3D printed, red water cube shape, it is truly good-looking, touched by hand, as well as a sense of lines. He pointed to the table about the size of an ordinary printer and equipment, told reporters: these items are made by this 3D printer, which uses melt extrusion rapid prototyping technology, the plastic heated to more than 200 degrees, and then A little bit with the nozzle out, for the accumulation of manufacturing. This 3D printer sold 10,000 yuan in China, the United States sold for 1,500 US dollars, it can even be printed on living cells.
