We created Mekanika with the wish to facilitate local communities' access to manufacturing processes, through open-source tools and quality educational content. All the tools we design are entirely modular, highly repairable and follow the core principle of open manufacturing: “design global, manufacture local”. With these core principles in mind, we decided to create our first tool: a screen printing press. It consists of a majority of standard parts, very easy to source online, and of a few specific parts used as connectors. These specific parts can be manufactured using CNC milling, a common digital technology that we see rapidly spreading around the globe. This tool allows to make one-colour prints on many different substrates. It comes with a printing board specially designed to hold t-shirts, but it can be easily changed to start printing on other clothing sizes or on other materials, such as woven fabric, metal, paper, plastic, wood, glass, ceramics or leather.
