[Questions] 3D Printers: are they worth it?

Hello everyone,

Basically I'll supposedly start a new job in September and I'm thinking of what to do with all that income. Since I don't have to worry about food, clothes, heat, etc. for now I can basically enjoy my whole salary (although I plan on putting a part of it in the bank, of course).

So here I am; I've heard about 3D printers a while ago, and I'm interested in getting one. and yes, this is totally a real thing.

The one in that link above is meant for the industry, and the process has evolved enough that many artists now use them - usually it cuts wax or foam.

I've tried finding a lot of sources, but I can't find much information about where to start. What budget should I look into, for example.

I am not much of an artist, so I guess I'd mainly use it to make figurines or reproduce useful stuff (such as a CD case for all those stray CDs I have lying around). The model I'm looking for I guess is one that can scan stuff like in the video, and won't need me to blow my money on "fodder" (the wax, foam or metal I'd use to print).

Thanks for any info!
