This past weekend I went to Artisan Asylum for an introductory training on 3D printing. Very cool maker space. I saw tank robots, hanging paper mache pterodactyls, a coffee table with an embedded bonsai garden and other creative gadgets.
One of the big training take aways is 3D printing is quickly becoming a tool for all. You no longer have to be a professional engineer or machinist to get access to powerful manufacturing tools like this. For example, there are 3D printers you can buy for less than $1000 dollars. If you are curious about 3D printing, check out this slide show. And if you are making or about to make 3D printed objects, check out Thingiverse, an online space for sharing free digital designs.
