Fellow RAM Members,
It’s been a long time since we went on a field trip. Actually, I don’t think that we ever have been on one. Anyway, our July meeting featured such an event. Rich, the Prez, arranged for the wonderful folks at Duncan-Parnell to show us the latest in 3D Printing. Cindy graciously drove us to the office site where we met several other members of the RAM group. There, we were entertained by Duncan-Parnell personnel Carlton McFaden and Joe Holmberg. When [I] think of printing, paper always comes to mind. Well, the latest in this technology produces functional models; no paper at all. The earlier stages of 3D Printing involved models used for design purposes. Today, items such as prosthetic limbs can be made through this technology. Some of the specific topics centered on were: Laser Resin and Laser Powder Based Systems, Color jet Printing, Range of Applications (Ceramic, Casting, Durability, Bio-Compatibility, Toughness, High Temperature Conditions and Optically Clear), and Selective Laser Sintering (Involving Injection Molding Grade Plastics). As a former machinist myself, I was impressed or should I say “shocked” at the applied process, the materials generated and the precision achieved, such as in gears and fan blades.
This was practically the most informative presentation I have ever attended – inside or outside of our group. We finished up with an extensive question and answer session while “stuffed” with the delicious lunch items provided. We were even given several samples to take with us and witnessed an item being made (a color surfaced bearing). I look forward to seeing this again.
