Dutch 3D printer manufacturer Ultimaker is continuing their tradition of opening up their products to their open source community by releasing the blueprint files for the Ultimaker 2 Go and the Ultimaker 2 Extended. The Ultimaker 2 Go was designed to be a gateway into 3D printing for new users, while the Ultimaker 2 Extended is a larger, fully loaded printer targeted directly at the Prosumer market. Just as with the release of the files for the Original and the OG Ultimaker 2, the hope is that their loyal community of users can help them continue to evolve their printers.
