Comment on TPU wall thickness for shoes

Great info, that!
We always keep the dryer at 45C (not sure why, we just do…) I just looked it up and it looks like 65C for 8 hours is a minimum for TPU. So unless my colleague left the spool of TPU in it over the weekend - which I doubt - it would not have been enough. Unless he took the spool right out of the vacuum-sealed bag with the silicagel packet in it. I don’t know. I’ll ask him.

I am rapidly discovering. That spools do not seem to arrive dry.
Also, desiccant will not dry a spool. It keeps the air dry and will prevent a dry spool becoming wet. With ASA, I am learning you always need to dehydrate before first use. But am hoping using desiccant and vacuum bags will limit the time needed when reusing an open spool.

They will limit, but not by as much as you’d want. Plastic bags still allow moisture to pass through even when they’re airtight. I live in a swamp, so drying is a necessity before every print.

Yeah. Those bags hardly do anything when the spool sits for months on a shelf.
