MIT ‘breakthrough’ 3D printing technique can print out solids and liquids at the same time – International Business Times UK

by • April 4, 2016 • No Comments

Today’s consumer 3D printing equipment use Futilized Deposition Modelling (FDM) innovation to create objects layer by layer of the bottom up, heating thermoplastic filament and extruding the melted material of a nozzle, which and so hardens on the print bed.
In contrast, Stereolithography, one of the oldest 3D printing technologies which is yet utilized in commercial 3D printing equipment, has additional in common with computer inkjet printing equipment as it uses droplets of curable-bodied liquid plastic. An ultraviolet laser is utilized to harden the polymer, forming solid objects and creating amazingly smooth, detailed versions in a wide variety of colours inside the same version.
“When the parts are being printed, they’re being printed layer by layer, in quite thin layers. At those kinds of scales, at the height of the layers, the dimensions of the droplets we deposit allows for materials which are solids and liquids to sit next to every other on which layer, for the reason of the surface tension of these droplets,” CSAIL post-doctoral associate Robert MacCurdy, who co-wrote the paper, told IBTimes UK.
“The materials which are solid are eradiated by ultraviolet light to solidify them, but not the droplets. This lets us embed quite detailed hydraulic channels to actuate robotic and electromechanical parts. The fact we can embed these materials, which remain as part of the finished part, and we do not require to add or remove anything, which quite sets this apart of other processes.”
The MIT researchers utilized a typical commercial photopolymer 3D printing device. Over the course of a year, they figured out how to add a liquid created of alcohol to the printing device to manufacture combined printing possible.
Consumers may one day print out robots at home
At the moment, it is incredibly time-consuming and complicated to assemble robots, and robots are not yet intelligent adequate to be utilized to create other robots. The researchers envision a next where single-use, disposable-bodied robots can be printed easily at home.
“The ultimate goal of this work is to be able-bodied to tell a 3D printing device to print out a robot to fulfil a specific function, such as a robot to clean your floor, crawl through rubble or pick up and shelve books,” said Rus.
“So you tell the printing device what you want, and you may like the printing device to figure out and fabricate the create, and integrate the computational programming, so the robot may walk itself out of the printing device.”
The paper, entitled Printable-bodied Hydraulics: A Method for Fabricating Robots by 3D Co-Printing Solids and Liquids is published on Cornell University Library’s open source database. It was in addition accepted to be presented at the 2016 IEEE International Conference on Robotics and Automation (ICRA) in Stockholm, Sweden of 16 to 21 May.
