Maybe or maybe not, but it is not far off in any case. Remember we already have a lot of infrastructure available from digital cameras (lenses, shutters, exposure measurement, etc.). 3D printing only needs to supply part of what is not in place. 3D printing is a means of manufacturing cameras on a much smaller scale than previous.
