Head and neck piece. 3D printers impact on designer makers.

I was wondering what impact the 3D printer would have on Art.  It seems that everything can now be made by this form of printer. everything from human skull parts  to houses so imagine my surprise when I found this:-

Quixotic Divinity Headdress by Joshua Harker

Found at http://www.contemporist.com/category/art/

Artist Joshua Harker has used 3d printing technology to create the Quixotic Divinity Headdress. The piece has nearly 200 hours of design time and was built by EOS using their largest format SLS printer.

The headdress will be debuting in the United States at the 3D Printshow New York City at the Metropolitan Pavilion in February 2014.

There is also a video on youtube here:-

I have to wonder

1. If it can really be called ART? or is it just designed because the printer actually does the making.  Is the absence of brush strokes and little imperfections complementary or detrimental to the finished effect?
2. how long will it be before the 3D printer takes over clothing manufacture? 
3. What if the printers become intellectually brilliant it can act on its own accord?

There are so many questions surrounding 3D printers that I believe a conference should be held as to there impact on student training.  This technology is racing so fast we are in danger of being left behind in catch up mode.
