During studying I am doing dj gigs at weekends. I saw this video where 3d-printed vinyl is really working. This is something which is going to blow up the bank! It is the way to integrate new and old-school.
Nowadays its easy to buy music from online stores in your favourite audio format. In future it is possible to do it + print it to vinyl and get back to old school style djing. THIS IS COOL!
At the moment decent 3d-printer cost about 1500 euros and prices are expected to go down soon. There is many manufactures I am now going to mention just one which I know is good and costs ~1500: http://www.minifactory.fi/en/
