A small fan cools the ABS/PLA to stiffen it when I print bridges or caverns. That prevents (or minimizes) the top-most printed layers from drooping while still hot and maleable. If you are saying cold organs last longer then tissue deposition 3dee printing (with bridging and caverning) can meet the nutrient and internal structuring issues head on.
My 3deee printed Salma Hayek IS possible. You have given me hope. Ole!
You’ll just have to thaw her out when done!
