I disagree that 3D printers are only for prototyping. I work on making useful robotics hardware that people can make on cheap printers. I think if you design for 3D printing you can develop some really useful hardware that people can make anywhere in the world. Ultra low cost injection molding as you described would be great, but that technology doesn’t exist. Meanwhile 3D printers can make custom parts more easily than before. This changes the way open source impacts the world. We’re already surrounded by open source software, but perhaps in ten or twenty years time we’ll be surrounded by open source hardware as well. https://youtu.be/LIkX7wniYh0 https://youtu.be/LIkX7wniYh0
