MIT scientists make it easy to tweak designs for 3D printing
Two different groups of MIT researchers found a way to print out objects with glass instead of plastic and to make a printer spew out 10 different materials at once earlier this year. This particular team along with researchers from the Interdisciplinary Center Herzliya in Israel, however, have chosen to focus on creating a system that makes it possible for even novices to customize the objects they want to print. Designers typically have to adjust a CAD file to tweak the object's looks by typing in numerical values, and then wait for minutes to hours for a simulation software to make sure the final product is viable. The system this group developed dramatically speeds up the process.
It displays the design along with sliders representing different parameters -- say, the height of a shoe's heel or the base size and width of a mug -- on a web browser. The user can then easily play with the sliders to achieve the look they want. Now, here's the best thing about it: it won't let you design unstable structures or anything that can't be printed or used. Nobody has to spend hours waiting for software to make sure the modified digital object is feasible, and all the user needs to do is to send it straight to the 3D printer.
