Hello, as many of us I use Shapeways services to build my master copies in order to clone them with silicone molds and then resin casts. One issue I noticed is that seldom I receive from Shapeways some pieces not perfectly dry. Those "wet" pieces have a problem when in contact with the liquid silicone used for the molds. Once the silicone dries It is supposed not to attach to the master copy piece. It is so just when the master copy is dry, when it is "wet" the silicone sticks on it making impossible to remove the mastercopy without damaging the mold. The solution is simple: dry every shapeways' piece out. But how? I do not want to damage them. What could I use? Alcohol? Acetone? I do not have any idea what to use... Excuse my horrible English, I hope I made myself clear. Thanks!
