In my opinion, being an owner of a 3D Printer myself, all current consumer 3D Printers are really not all that useful. They are awesome to use, and fun to show our friends. However, when it comes to using them to saving money, making useful things, or saving the world, they are pretty worthless.

Does anyone agree here? I love using my printer, so don't get me wrong. It's just more entertainment, than anything else for me right now. I feel the same can be said for about 80% of all other 3D Printer owners.

It's not until we can print in a greater variety of materials all at once that 3D Printers will become useful.
