The world's first printed aircraft has flown. No, it was not a paper aeroplane. Using an industrial 3D printer, some engineers manufactured the complete airframe of a UAV.
I wonder if how long before someone tries this on a hobbyist 3D printer. The future of small scale manufacturing is already here and it can only get better, cheaper, and easier. Looking around the EOS website, the P 730 mentioned in the article is already a previous generation model.
