I am thinking about using FastWax on the 530. I have a couple of questions regarding the new wax. It would be great if someone who uses the FastWax can help
1. Does the resign expand during the lower temperatures of the burnout?
Unfortunately we do not have access to special resin investment powders which are stronger and do not crack due to resin expansion (green strength).
2. Can you print and cast solid items e.g. signet rings?
3. Any problems with lettering? Sharp angles, indented letters?
