What’s your resin 3d printing setup like? Specifically on the chemical waste side of things, how does disposal work in Tokyo vs [insert generic stateside metro area]? I guess this is more of a question about Japanese infrastructure for disposal of small-scale hazardous waste and possible connections to “the will to have nice things”.
In exchange for this information, I offer 2 lesser known tips for resin printing 😁 (that I assume you may not be aware of yet):
Ultrasonic cleaners are way more efficient and effective than pickle containers and toothbrushes at cleaning (though more expensive).
Hot (near boiling/as hot as you’re comfortable touching briefly with a gloved hand) water makes most supports quickly and easily peel off in seconds (saving tons of time). Dunk models in the water for about 10 seconds at a time. Remove supports with (gloved) hands until it starts to cool. Repeat until they’re all gone.
Naturally, there’s a burn risk here, so this tip comes with an obligatory “use at your own risk” disclaimer.
There exists a type of resin called Ekimate in Japan which is much less smelly/irritating than most resin formulations, costs ~3X as much, and which represents itself as being pourable down the drain in a matter which suggests to me that lawyers/etc have reviewed the claim and think it is within appropriate bounds for marketing material made by chemical manufacturing companies. I do not pour it down the drain. If I had a high tolerance for running wonderful small businesses with inventory, I would try to get their exclusive license to distribute in the US and make it a thing; it’s an obviously better (though premium) product than any other resin formulation I’ve seen.
My liquid waste gets cured outside in sun for several days while evaporating to reduce volume then wiped up with towels and discarded in standard (burnable) trash; my solid waste gets cured out of an abundance of caution then discarded in standard (burnable) trash. I have immaterial use of IPA which is not discardable in trash but which also evaporates easily, and simply let it evaporate outside after I am done with it (after cleaning/reuse cycles).

I use exclusively water soluble resins.
