One last thought that I would leave you with: Air filtration. If you wish to eventually want to print some of those engineering filaments, or even the old standbys ABS/ASA, you need to have a working air filtration system to remove hazardous particulates and VOCs. This means activated charcoal filters. Some brands are better at it than others, but most of the manufacturer’s are at least acknowledging the need for it. And some few want you to believe their marketing over actual performance-- cough, cough Bambu’s new P2S cough.
