Current 3D Printers: Useful or Just Cool?

[Vanguard]

I thought the same thing, people are only printing toys, not really much going on. I am now changing my opinion, it looks like a large majority are being used to develop new products, print prosthetics, research, disaster relief, and many things I would never have thought possible. It has inspired the creator in so many people, and with the primary adopters being young people, it can only improve.

The technology has improved dramatically in a VERY short time, but physics limits how fast filament technology can go. Is fluid printing going to be the future ? From looking at Peachy, it would look like it might go that way. It seems to me to hold more potential than forcing a piece of plastic through a hot piece of metal to become a piece of plastic.

Just my opinion, thanks for the great thread.
