With open source we don’t mean everyone owning a printer can start printing in their living room. By open source we mean the design can be produced in a decentralised network of hubs all over the world. Which makes the mask and knowledge accessible and adjustable to local resources and needs. Open sourcing is a way to make the product sustainable. Once a viable product is designed it can be spread in no time using all MJM printing units in the world. This is the only way to beat the excesses of creating scarcity in times of crisis.
