For starters, you’re going to want an FDM printer. Resin printers can be nice, but there’s a lot more complexity to handle when you’re just figuring out how to print stuff.

I’ve been using an Ender 3 V3 KE for a few years. It’s been pretty solid. I can use any slicer I want, but the one from the manufacturer, Creality Print, has been pretty good for me. Most printers can use any slicer you choose, though the slicer designed for that printed will often give better results (until you figure out what specific settings you need).

Choose a budget, and then look for a printer with a direct drive extruder, auto leveling bed, and a heated plate. An enclosure is very nice, but I did fine for years without one. I recently bought an aftermarket enclosure after I started doing more PETG prints.

Multi filament is a cool feature, but that’s up to you if you want to pay for that. It does create a lot of waste, and you can always tell the printer to pause at certain points for you to change filaments for those times you want to do different colors.

Overall, I always recommend a simple-but-good printer at a reasonable price when getting started. Having convenience features will make the whole process easier, which I find makes it easier to learn.
