Like the tin says. I don’t think it’s exactly easy to abuse- synths have a windup for applying it to themselves and I assume it’s similar for robolimbs.
you can’t apply it to yourself as a synth
it doesn’t need to be printable though idk when you ever use it unless it has more in game functions
you can use it to fix robot limbs
its supposed to be used to fix robot organs
Synthetics mechanically can not heal themselves with nanopaste. Its a very niche item.
As MT/CE I try to grab the maint stack near upper engineering- if a synth needs a lot of blowtorch/wire repair nanopasted heals both damage types instantly per application. A lot faster and if the synth was hurt so bad they need a defib it can sometimes use most or all of your wire stack.
