    Yup, each batch needs to be stored in controlled conditions for the entire length of the expiration period. Many times the product expiration period is much longer, but controlled storage isn’t cheap, so just companies just do the minimum required by them.












  • My dad works for the DOT in a state that has a large homeless population. After the police remove everyone from the campsite, the DOT goes in to clean up.

    And by clean up, I mean thely just throw literally everything into a big dumpster. Although apparently it can be pretty gross due to the unsanitary conditions (no toilets) and drug needles laying around, so they get ‘hazard pay’ and overtime pay for the job.

    I’m sure the team of cops get ‘hazard pay’ and probably overtime as well. This usually takes a day or two and happens every few weeks. The cost of labor alone to temporarily displace these homeless people must be astronomical… I bet they could build so much temporary/transition housing with that money instead.

    Oh, and I forgot to mention that the police usually only remove these encampments in wealthier neighborhoods and let the poor areas deteriorate.





  • As someone who does R&D testing on plastics that are used in medical devices, I have some insight. Of course the type of plastic matters, but all plastics use carcinogenic chemicals during the manufacturing/extrusion process.

    To make most plastic, a polymer resin is mixed with additives such as solvents, plasticizers, and stabilizers at high temperatures. Ideally, you want the additives to evaporate out during production so that you’re left with just the newly formed plastic.

    But some of these additives get trapped in tiny air pockets between polymer chains. When they’re reheated, the polymer chains relax and release the volatile, carcinogenic additives into the air.

    This is likely where the toxicity is coming from, not the polymer chain itself. So regardless of the type of plastic used, reheating the polymer during 3D printing will release some volatile additives.
