I have been involved in the additive manufacturing industry for almost 10 years. Before that I spent many years working with leading edge plastic injection molding technologies. In the past I have worked for two of the top 5 players in this industry (in my mind those companies are 3D Systems, Stratasys (Ticker:SSYS), Z Corp, Objet, and EOS). I have also worked closely with most of the large resellers in the 3D printing industry. I have worked as a consultant to companies evaluating which additive manufacturing machines to purchase.
