3D Printing - Wrench Wednesday Question

6/25/14 - It's Wrench Wednesday! The attached picture is an industrial 3D print of a refinery somewhere in the middle of America. It was printed it on our Stratasys Fortus 400 3D printer. The question is...How many hours did it take to print

Here's a hint...the print consists of 4 individual prints 8" x 8" and the time range was between 50hr's and 200hr's.
