Cincinnati, Ohio is best known for the Bengals, Bootsy Collins, and Skyline Chili but it’s about to become famous as one of the first cities with a true market for 3D printable designs. 3DLT, a small company based in Cincy and founded by a team of programmers, is bringing the free-for-all world of 3D modellers into line and essentially making an Etsy for ABS.
