Probably the easiest/cheapest way to get into it is with a Mini printer. Monoprice has a Mini version of my Maker Select Plus.

You can find a refurb on their site or catch it on sale for less than $150 bucks usually. It’s the cheapest way to figure out if you’ll enjoy/need/use FDM 3D printing. Obviously it has a small build volume but it’s a fairly reliable and accessible first printer.
The next step is to see if you want to learn to design your own parts using something like TinkerCAD or Fusion360. It’s relatively easy to pick up but it might take more time for people who aren’t familiar with design in general. You can also search for things/parts that you might find useful on sites like Thingiverse which is a free repository of 3D Object files that you can just upload and print.
You’ll see a lot of reviews online of people printing little dolls and figurines and other shit like that. I tend to only print practical things, so I don’t find those reviews all that interesting. For instance, I just designed and built a dust collection adapter for my miter saw to connect to a shop vac hose.
I’ve been doing small projects here and there with my printer over the past couple years but am considering upgrading to a much nicer printer with a large build area. Ask any questions you might have and I’ll do my best to answer them.
