3D Printing Directory
3D printing creates real, solid objects one layer at a time using digital data. 3D printing may therefore soon do for manufacturing and medicine what computers and the Internet have already done for the creation, processing and storage of information. For an explanation of 3D printing technologies, opportunities and implications, please see the 3D Printing page, my 3D Printing videos, or my book 3D Printing: Second Edition.
The 3D printing marketplace is now evolving extremely quickly. This directory brings together links to many of those organizations currently developing and producing 3D printers, as well as some of those pioneering their application. If you know of a site that should be included, please let me know.
