It is very impressive to see how the world has come to such an era where 3D is the standard. Desktop 3D printing is quite a discovery. It might be useful for business sectors like an architectural firm or a design studio but whether 3D printing has any value for home use will only be answered as the present proceeds since there isn’t a dire need of it yet. However as people become more creative soon 3D printing will make a major impact in the market.
Same way i feel , it can print objects but nothing of use just trinkets and knicknacks if that was the word for it. The closest thing I can see them making the soonest that might be of hep is medical supplies maybe.
