I copy and paste here a post i made to kickstarter and feel was not answered that I had posted directly to Rinnovated already a few days before (I have added numbers on the questions):
+++++
1.Maybe I have missed this somewhere but what should we think about reuse of unused resin and water that has been used in a peachy print at least once? I think this tells us how exact we need to be to reduce the amount of scrap material between printing runs.


2. Roughly how much useful life do you all think the remaining resin has once the resin is put together with the water in your current design? hours? weeks?


3. According to the makerjuice subG spec and MSDS which I understand can be and has been so far used (? could be subG+ being used but there are no data sheets for the + that I find) :


ref MSDS subG:
Hazard Statements:
Causes serious eye damage
Causes skin irritation
Harmful to aquatic life with long lasting effects
May cause an allergic skin reaction


ref : Technical Data sheet SubG:
Storage:
Store in a tightly closed, opaque container in a properly vented storage area under dry conditions away from heat, sparks, and open flames. Shelf-life is 6 months from receipt.


4. First, can you tell us where you think the peachy resin will/could differ on these?


5. It seems the resin makes the water toxic as it states "Harmful to aquatic life with long lasting effects".. so the water I am guessing should in all likelihood NOT be poured down the drain? the other things regarding eye and skin as well as allergic reactions are at least to me expected but it tells me I do not want to do this in my home and maybe with some kind of fume hood? if so I would be thinking about a much more sealed design (the laser sealed within the lower resin container to reduce fumes and possible irritations.


Regarding storage then it states "Store in a tightly closed opaque container". This also tells me that I probably do not want to leave out the resin within the open and transparent peachy as being shown but again a more sealed design.


6. But the text continues with "under dry conditions".. so then it seems that putting the resin with the water is already limiting its useful life and limiting the ability to reuse it? Then If reuse is possible I would guess you would want to separate the resin and water as much as possible but just how far one may want to go will depend on the effect of the water on the resin and vice versa. Any insight into this would be great and any suggestions on how you now think one would separate?


7. It also mentions about ventilation as well as the heat sparks and open flames.. to me this seems like typical chemical safety not so impacted by the peachy's innovative design. But if I were to integrate the laser into the resin container to reduce toxicity while it was working I would probably make it removable as well?


8. Finally this storage text also states "Shelf-life is 6 months from receipt". 6 months is not a really long time it limits perhaps how much material one may stock up on to reduce waste. What happens after 6 months? have you tested material that is more than 6 months old?


So far this leads me to think that the containers for the peachy would be best suited to maximize the resins longevity and to manage the contaminated water while reducing toxicity in the environment if they were opaque and resealable with the laser somehow integrated or suspended in the resin container. I am thinking depending on the useful life of contaminated resin that between prints one could contain in one the mostly separated reused resin and in the other the contaminated water and either.



your insight into this is much appreciated.
