Design Sharing Platforms

We refer to online platforms where users share designs of physical objects (hardware). There is a growing number of them and some encourage free hardware, while others help users keep their work non-free and exchange them for money. Some offer various CAD and/or CAM software capabilities or connect users with printing or machining facilities. Some are dedicated to a specific domain, like electronics, or space development. Some platforms are controlled by one company while others are governed more like a commons. These aspects enhance or limit the users' freedoms. In this page we seek to help users choose the platform that aligns best with ethical values and maximises user freedom. Therefore we build a list of the current platforms and indicate their main aspects.
