Parts are definitely of 'prototype' quality, but it is still amazing to go from cad file to finished part in an hour in my dining room. If anybody wants to try a part, let me know. We will have to figure out how to get an .stl file, but once I have that it is just a little bit of printing time. Maximum dimensions are about 3" cubed, some manufacturing considerations, like hollow things are difficult. Lots of ideas here: http://www.thingiverse.com/ Matt On 09/30/2011 12:36 PM, Ernest Christley wrote: > -Some of the plastics being used are useful in lost wax casting techniques. > -What?
