The Ember 3D printer ships with 2 liters of our Standard Clear Prototyping resin. We affectionately call it PR48, which stands for polar resin number 48. Like WD-40, is this our 48th try for a polar resin formulation? Close enough. Today we’re sharing the formulation of PR48 under a Creative Commons Attribution-ShareAlike license, the same license Arduino uses to share their design files. We’re explicitly inviting you to understand, remix, and remake our resin.
PR48 will soon be for sale here on our site (Ember explorers, contact me here, if you need more right now). Buying it from us will probably be the easiest way to get more, but if you want to make your own for any reason (and are experienced with resin formulation, or perhaps just chemical handling) you can do so.

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.
