There seems to be considerable interest here in 3D printing.
Here is a FREE Webinar that you can register for if you have the time, and of course proper computer connection, to watch.
I would be sure to come up with a company name, even if it is not authentic, if you fill out the registration form.
Tho the prices have come down on 3D Printers, they are still out of reach for most hobbyists.
