3D Printing
Desktop 3D printing is full of confident, contradictory advice. KnowDepot’s 3D printing guides do one thing: reconcile what the community actually agrees on, across forums, subreddits, Discords, and long-time makers, into clear decisions you can act on. Which filament for which print? When to upgrade versus buy a second machine? Which mods are genuinely worth it, and in what order? We read widely, cite our sources, and are honest about where makers disagree, so you can skip the twenty-tab research spiral and get a calm, balanced answer. We don’t pretend to have lab-tested every printer; we tell you what experienced owners consistently report, and where the consensus breaks down.
PLA does not melt in a hot car, it softens and sags near 55-61C. Here's how hot a parked cabin gets and which filament to print instead.
