Researchers at NC State have developed a way to print liquid metals into 3D structures at room temperature. The structures are stabilized by a thin oxide ‘skin’ that forms on the liquid metal. The approaches shown here represent new ways to direct write metals in 3D. In addition, the resulting components can, in principle, self-heal ( “Self-healing stretchable wires” ) and be ultra-stretchable ( “Ultra-stretchable wires” ).
The paper, “3D Printing of Free Standing Liquid Metal Microstructures,” is published online in Advanced Materials….
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
