Guide recommendation for absolute newbies? (lemmy.ca)

I am interested in getting a 3D printer but I have no idea where to even started. Is there such thing as a multi-purpose printer? What’s a good source to read up on printers, software, filament?

I am thinking small replacements items like drawer guides, funnel for espresso machine, essentially little parts and pieces that break around the house and farm. Also maybe some device cases (including outdoor ones) etc.

Ideally I don’t want a closed system. I have a Cricut for 10 years or so and I hate being locked into the app so much. Unless there is a really, really good reason.

Edited to add: Thank you all! What an amazing community!

Other things to note regarding filament- if youre only planning on making items for indoor use, PLA / PETG will be fine. If youre planning on using things outdoors or in hot temps, you'll want to look into more advanced filaments like ABS/ASA, Nylon, etc. These absolutely require an enclosed printer, whether thats part of the design or something you put over top of it to keep the temp inside higher. I'd highly recommend figuring out your ultimate use case and make a decision around that.

    Good point! I definitely would want to consider outdoor use items.

    Just a couple of notes: Your material of choice isn't a final one. Most printers can print most "normal" filaments, such as PLA, ABS, PETG, ASA, etc, and if you start with one, moving to another isn't a big deal. The only caveats here are:

    • Some materials are harder to print than others. PLA is generally considered the easiest, and personally I find PETG pretty easy too. ABS is a really durable material, but can be a PITA to print.
    • Some matererials are considered abrasive, so you'll need a hardened nozzle.
    • Some materials, such as ASA and ABS, cause toxic fumes during printing. Proper ventilation is important for those.

    For outdoor use, the main factors are temperature tolerance and UV resistance. I'd advise against PLA for outdoor use. PETG is slightly better in these regards, and I am currently testing how well PETG handles a Scandinavian outdoor climate, and things look promising.

    I would love to hear about PETG’s performance during a Scandinavian winter. I am on Canada and soil sensors I would pull over winter but some other stuff might be interesting to leave outside. For ventilation I could either use it outdoors (summer) or in the garage in winter unless it needs room temp to print. That would be an issue in winter.
