Is 3D Printing Hyped?

There is an upcoming expo where I will be giving a brief talk on 3D printing.

The impetus for this topic was a Japanese ‘expert’ in 3D printing.  Oddly this expert and many like him seem to take popular sentiment, temper it with a small amount of sophistication and think they have discovered the secrets of the universe. In this case, he was arguing that 3D printing is a hyped technology because it is slow, limited in materials, and cannot provide good surface finish.

Naturally, I disagree and give some reason why I think 3D printing is going to impact us significantly. The major problem seems to be that people are mistaking the machine with the method. You can come watch the talk on the 20th in the afternoon if you are in the area.
