Over the past few months I have interviewed a number of Solidscape "Protobuild" users with a specific eye to correcting the blistering effect seen on investment castings. The summary of recommended procedures can be viewed at http://www.a3dm.com/a3dm_casting.htm I have tested these methods on models built by my RapidToolmaker where the surface is smoother and have noted a significant reduction in surface anomalies. The same methods should work for the Solidscape material as well.
