In addition to learning how to run the EOS P385 SLS machine, I have learned to run older 3D Systems SLA250 machines, compression molds, and a little urethane casting. I am getting ready to learn to operate the SONY 9000D SLA machine; amazing build envelope and very touchy. I am also embarking on a rather complicated Warhammer 40K diorama, of which about 90% will be scratch-built.
