Good Morning, Michael

I continue to search for a solution to 3D printing my patterns for foundry casting. .STL or IGES is the preferred format for these printers. Unfortunately, the quality is just not there yet to eliminate post processing of my patterns, primarily because of the step pattern left behind by the slicing software and the limitations of the printer. The consortium that is preparing the format claims that it eliminates a number of problems inherent with .STL. I am always looking for solutions to the post processing necessary for my patterns. I don't know how the slicing software deals with calculations that may reduce or increase the volume of any given pattern. If 3MF provides for a smoother and more accurate output, then I'm for it. I have submitted one of my patterns to Shapeways to be printed on their EOS SLS printer to see if that might be a possible solution. Anyway, I was just enquiring. Thanks, Michael
