Sorry for the title, I am the unhappy wife and I need your help, please.

Husband has a 3D printer set up – he's very proud of it, and I'm pleased for him. However, the plastic stuff he's using is SO strong smelling. He has it in the basement, vented out of a window and it's in its own designated tent, but I can still smell it. Last night I kept waking with the smell and my nose is so stuffy today.

Can you please advise what kind of… I'm not even sure of the term, is it filament?, he should use that doesn't smell? I don't want to be a kill joy with his new hobby – it brings him so much happiness, but I honestly can't do this. I know I am seriously sensitive to smells, but this kind of goes beyond that for me as it's making my eyes burn and my nose is so stuffed up.
