In this video, Stefan of CNC Kitchen makes an amazing discovery. By annealing 3D prints in plaster, you can significantly improve their strength and their heat tolerance.
He did have some issues with “demolding” the parts from the plaster and plans to do additional tests. It will be interesting to see where this leads. As someone adds in the comments: “Before putting in plaster, coat with a sealer and then a mold release. Avoids moisture absorption and reduces cleanup.”
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.
