满足未来的建设:麻省理工学院3 d打印整个建筑原型


编辑:admin 时间:2018-09-28

In little more than half a day, an innovative 3-D printing machine built an igloo-shaped building half the size of the US Capitol dome。 It did so all by itself with minimal human oversight, not too different from how you’;d hit ‘;print’; in your living room to create objects with a hobbyist 3-D printer。 This remarkable demonstration of force could be truly transformational  —; and not just because it could revolutionize how we erect constructions here on Earth but on other planets as well。 It’;s likely that any extraterrestrial manned colony will use a similar method to build a base。

Just hit ‘;print’;

The machine is just fresh out of the Massachusetts Institute of Technology’s (MIT’s) materials science and design focused Mediated Matter lab in Cambridge。 It consists of a tracked vehicle equipped with a very large industrial robot arm that has another smaller, precision-motion robot arm attached to its end。 Sort of like Alien mouths。

The highly flexible and precise arm can then be used to direct any conventional (or unconventional for that matter) nozzle typically used in construction works such as pouring concrete or spraying insulating materials。 Called the Digital Construction Platform (DCP), the prototype has a combined reach of 10 meters and also carries solar panels and batteries so it can be deployed anywhere。

Most 3-D printers, be them for printing plastic, metal, glass or even human cells, involves a closed, fixed structure that supports the nozzle。 Typically, you can’;t print objects bigger than the printer’;s enclosure itself —; but that’;s not the case with MIT’;s machine。 Because it’;s free moving, any object of any size can be printed this way。
