Gillette’s 3D Printed razors

Posted on Updated on

According to Donato Diez Gillette and Razor Maker™ co-founder and global brand manager, “Our partnership with Formlabs, and the power of their 3D printers enable consumers to have a say on how their razors should look. We are excited to work with our Boston neighbors to pilot this breakthrough concept of customization”.

3D Print Metallic Glass

Posted on Updated on

 

Yale Professor Jan Schroers and his graduate students have developed some unique uses for metallic glasses, a particularly tough metallic alloy that can be molded into useful products (like cell phone cases) at relatively lower temperatures and pressures. According to Yale Professor Jan Schroers and his research team,” they used a new approach to 3D print objects from the metallic glass a relatively new material stronger than even the best metals, but with the pliability of plastic”.

3D printed active materials for robots

Posted on Updated on

3D printed active materials for robots, inspiration from invertebrates.

According to Dr. Ed Habtour, ARL researcher who specializes in nonlinear structural dynamics and lead author Ghazaleh Haghiashtiani, “Current military robots have two major limitations that restrict them from mimicking the locomotion of biological organisms. Unlike current 3-D printed DEAs, the new fabrication method does not require post-processing steps, such as assembly, drying or annealing. With the new 3-D printing method, the Solider can take advantage of the unique actuation properties of soft DEAs at the fundamental materials level with microscale resolution and complexity, with minimal prior expertise.”
