This Article shows how the maturing technology of three-dimensional printing can be used to construct an enforceable open hardware license. Open hardware lacks the legal tools which allow the easy implementation of enforceable open source software licenses. As such, existing licenses cannot successfully implement open hardware principles. The author proposes the “Three-Dimensional Printing Open License” (the “TDPL”). The TDPL draws on the unique characteristics of three-dimensional printing to construct a license that incorporates enforceable documentation, attribution and copyleft provisions. As the technology of three dimensional printing improves and is gradually integrated into a broad range of industries, the scope of the license’s application will increase.

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.
