The Logistics Of 3-D Printing A Cow In Portland

A Meetup.com group of 3-D printer aficionados, the PDX 3D Printing Lab, in Portland, Oregon, spent several months planning and 3-D printing a life-size replica of a cow. Yes, a cow. The model is made of PLA (Polylactic acid) material, a regularly-used type of 3-D printing material, printed with 14 separate 3-D printers representing 700 hours of printing time.
