I think 3D printing is great innovation, but it has its limitations in the consumer market. Over time 3D printed parts will get cheaper and be of better quality. The 3D printing on the M60 seems fragile. Rich already broke one of the front fenders. This Chieftan is molded in styrene (or ABS not sure) and IMO would be much stronger than a 3D printed tank. Can't wait to get it. I'm guessing my Chieftan will get here in late November.
