3d printing technology is amazing. Just read about 3d printed violin and some interesting project which appeared.
Everyone knows that wood is the leading material used in the production of musical instruments. It turns out, however, that this is not the only material that is able to guarantee adequate sound. The violin can be just as easily 3d-printed. See just how they sound that kind of violin.
If you have an access to a 3D printer, you can buy materials and get STL source files which allow you to print it. Printed violin can be purchased for $600 at the official website Hovalin.com.
Hovalin.com is an admirable open source project of 3D printable acoustic violin. The hovalin is a functional acoustic violin that can be produced using most standard consumer 3d printers. The total cost of raw materials for the violin (4/4) is currently about $70. The hovalin was designed with Autodesk Fusion 360. Its shape and dimensions are inspired by the Stradivarius violin model.
Hovalin project recommends three 3d printers: Dremel Builder, MakerBot Rep 2, Ultimaker 2.
