Renishaw for Empire Cycles launched the first 3D printed bicycle frame,from dezeen.
According to the brand, 3D printing makes the frame lighter without forfeiting strength by using topological optimisation – the process where material is removed from areas of low stress until the design is optimised for load bearing. Using as little material as possible means the frame is at its lightest.
Even though titanium is more dense than the aluminium alloys that Empire Cycles normally uses, topological optimisation allows the weight of the bicycle to be reduced to 1400 grams, which is 33 percent lighter than the previous 2100 grams.
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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
