Seems like these days we can 3D-print just about anything. Case in point, a musician from the University of Texas at Austin recently designed and 3D-printed a special 6-string electric violin because he wanted to play a unique composition. Sean Riley wasn't alone in his quest, he collaborated with a mechanical engineer and a sculptor to realize his dream. While it took a year to complete, the violin wound up costing only $10 in 3D-printed material. Cool!
