I absolutely agree with the whole issue of 3D printing, so my personal issues are more to deal with my specific application than with the process. Just an FYI; I make 1:16 and 1:8 scale steam locomotives; soft plumbers solder does not hold up well on most parts of the locomotive. I've had issues, and have seen some messes when people used soft solder for detail work. For sealing water containers (locomotive tenders, etc) soft solder is ok. These things have coal fires that glow orange when running, and the water in them is at about 170 degrees c. and do indeed get hot. Just fyi; right now my silver soldering of a copper boiler outside (hope to complete 2 this summer) is with Easy flo 45; it melts at 1125 degrees f; 605 degrees c. In shade, the copper sheet glows cherry red/orange, and brass will melt not much higher than that - I have melted brass components by accident before. (whoops…) I think we are all on the same side of the fence here, just waiting for technology to catch up to all of our needs/price points.
