Been using printers for over 7 years now, started them using them as a teenager and not knowing a lot so used to play about with things. Now using them as prototyping ideas, jigs for woodworking, making my own parts and also general use items for tools or on a machine. Others are using them for making molds so they can cast items, structural bits and bobs for their designs, printing parts for other people so a little income from that.

If you are looking for a good starter, don't buy one of the cheap ones as you will have head ache after head ache. Problems with adhesion and bed warp, the list can go on.

PLA is a much better plastic to start out with, or PETG. ABS can be hard work if you are new to the printing scene as it often warps and can suffer layer bonding issues if you do not set your temperatures correctly.

If you haven't already purchased one.
I'd recommend going for an Ender 3 or Ender 5, fairly well priced and a lot of support out there for modifications already done so all you need to do is print them.
