We've just reviewed the agenda for the upcoming October 20-23 3D World Systems Conference in Charlotte NC, USA.
The conference is intended for professional users of 3D Systems printers, such as the SLA and SLS Pro printers, and is probably not appropriate for hobbyists to attend. However, it's interesting to note the presentation topics include several sessions on 3D Dentistry, Manufacturing techniques and Jewelry making. There is even an intriguing session from NASA called, "How Do You Move a Spaceship? - The NASA Crawler 3D Printing Project". We did not realize the extent of interest in 3D technology from the Dentistry industry.
You can examine the entire agenda here. Note, this is a vendor-sponsored conference, so don't expect much information regarding other devices or manufacturers.
