Jim gave an excellent talk today about 3D printing to the local chapter of the National Model Railroad Association (NMRA). This weekend is their annual Education and Training Conference, being held in South Bend / Roseland. It turns out that their magazine ran an article on 3D printing last month, so they were already well versed in the basic concepts and eager to learn more.
Jim’s presentation started with a brief overview of the printing process, which included a brief demo of 3D CAD and slicing. He then started his printer making the same part as in the demo. While that was running, he discussed 3D printing technologies, materials, and some advantages / disadvantages of each. Several samples pieces were passed around the room. Many good questions arose from the group on subjects such as the applicability of certain materials to given situations. The questions indicated to me that the group was understanding the talk quite well and thinking ahead a bit. Jim showed his quadcopter, explaining how almost all of it is 3D printed – including the mold for the soft isolation mounts. Towards the end of the talk Jim discussed open source software typically used in the 3D printer community. After the talk several people stayed (during their lunch time!) to talk, ask questions, and just visit.
Overall it was a great presentation to an audience eager to learn about 3D printing. Jim did a most excellent job. Expect to see a visitor to two at the next Hive meeting.
