Has 3-D printing gone mainstream?
Not if this display at my local tech store is any indication. You, too, can print a model as an actual 3-D plastic object that… um, is brittle and breaks.
But, but, wait! Look at the glasses it prints out:
Those glasses are just great, except for the ragged bits of plastic that might cut your face, and the lack of a place to put any lenses.
The printer costs a thousand dollars. The plastic comes at less than a kilo for fifty dollars. The showcase product isn’t workable.
Sigh. I’ll check back in in three years.
