Filters for the bio-fermentor finally ready to ship, a week after placing the order… We’re so spoiled by AMZN Prime. Makes me think back to ordering stuff from catalogs by mailing in an order form. wow. anyway, they should be here this coming Thursday.
On another note; I’m starting to question my decision to 3D print the mixer part of the apparatus.
3D printed parts, even on the highest quality machines tend to be porous to varying degrees & also typically have large voids inside their structure.
This means that the liquid media & mycelium could intrude into this structure & also unwanted mold spores etc. There would be tons of crevices for these spores to shelter in along with dead mycelium & old media to further shelter them, to the point where they could easily survive sterilization.
Sigh… of course I already bought the relatively expensive poly carbonate filament. If I had access to a resin based 3D printer and appropriate material to print with, I might still be able to stick with this design, but I don’t. Soooo, I’ll probably have to form something out of SS sheet which has it’s own problems.
