I don't see how standards could deal with how parts are made. Where safety depends on physical strength, standards can include tests to make sure it is adequate. The same applies where safety depends on, for example, the integrity of insulation inside components. The preference order for specification in standards is: 1. Specify performance - does not restrict innovation; 2. Specify design - might not restrict innovation; 3. Specify construction - severely limits innovation. With best wishes DESIGN IT IN!

Still looking for opinions on the question though - do our Standards consider how the part is made? If not, does it matter? My gut says it doesn't matter, our Standards are written to evaluate a design, regardless of how it's manufactured. But is that thinking still valid?

You can just delete '3 D printed' everywhere, except in the first case, and it is still true. The first case is a red herring; the printer failed and caused damage. But if it complied with 62368-1 (or maybe 60204-1), the wires would not have come loose and/or would not contact the heat source. With best wishes DESIGN IT IN!

I wonder, however, if it's a mere scare tactic by Travelers for more insurance, or is there something more to this? In theory, the requirements for any part (regardless of how it's manufactured) are covered in our Standards, right?? Has anyone ever looked at the requirements from a view of how the part is manufactured? Should we? How do we know the requirements are adequate regardless of the mfg'ring process? How do we know we're not missing something? If the link below doesn't work, google Travelers preparing for the risks of 3D printing in manufacturing and it should come up.
