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.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
