Hey everyone! So I stumbled upon something potentially very cool from a supplier of mine. I was looking at printing the casting patterns and he mentioned using Machinable Wax's filament used in a loss-wax method of casting metal. In my line of work, this is very interesting to me, but was wondering if anyone else had tired the filament. I ordered myself a sample and will test it out in the printer. http://www.machinablewax.com/product.php?product=52 and apparently there are a number of foundries that will use the prints you make in their casting process. seems to be pretty cheap over the traditional methods.
