There’s a lot of talk abut 3D printers these days, but what are they good for besides for printing silly knick knacks and toys? German paper airplane enthusiast Papierfliegerei demonstrates the true potential of 3D printing with this year old video that has only gone viral now.
Using his expertise, he built a handheld paper airplane launcher. The shooter takes a piece of paper and pulls it through a short assembly line until finally launching the new plane into the air. So cool!
