This guy never grew up. Pouring molten metal on living things is not cool. GPR + 3D printer would give you the same results.

Yes, you can (part by part perhaps), though there's at least one 3d printer that costs under $100.

Right, but can I 3D print a 3D printer? If I'm paying $2.2k, I'd like to recoup that by selling a copy of the thing I just bought.

One of my ex-coworkers actually was part of a company that makes 3D printers that are just about cheap enough to buy yourself. Starting at $2200, it's reasonably feasible to buy one yourself if you have a good chunk of disposable income.

Another cool thing that came out of this is http://www.thingiverse.com/, a huge database of models you can print out.

I sound like a marketer, but I promise I ain't.

This is a proof-of-concept step with the technology as far as guns go, look to the near future for more wild and crazy DIY with much more than weaponry-Once they are able to provide ultra-durable raw materials (nano-esters, poly carbonate crystals, etc.) for the sludge they feed these printers the game will change overnight.

Well it will only set you back about $850,000 to get the printer so...

make money with a 3-D printer

Now I bet you could make one from a 3D printer! Welcome to the year 2000!

Make food 3d printers that can "print" each "pixel" in any color, taste, and consistency.

Then print corgi puppies with properly colored crunchy bones, and meat that taste like chicken.

Read this story - http://gizmodo.com/6-500-silk-worms-spin-one-heck-of-a-cloud-510908939
Silk Pavilion consists of 26 silk polygons which act as the structure of the piece. Made of silk thread laid by a Computer-Numerically Controlled (CNC) machine, the polygons were a template on which to place 6,500 silkworms which produced natural, unprocessed silk patches. The silkworms worked until the whole structure had been covered.

The CNC used an algorithm that had analyzed the patterns in worm-generated patches of silk, and then produced the first level of structure. The silkworms themselves created the second level, working as a sort of natural 3D printer. This gets to the heart of the piece as an interplay between natural and digital construction. The next trend in interior design should definitely be loosing thousands of silk worms on your house and letting them redecorate.
