Will IKEA become the next RIAA?

With 3d printers coming becoming household friendly in the next 20-30 years which will use plastic or metal materials and possibly more, the "design premium" on common goods be dead.

People will just download cool CAD specs of cups, vases, etc. and render them at home. Legally on not, 3D design will be only a series of 101010101 to be bought, or hacked and torrented.

Will a man in a van come to your home with a muli-material 3D printer (for the poor of course, the rich will have there own in-home store) and render what you need?

when you're done with your new toy you can recycle it yourself

Will some 12 kid in guam on a hand-cranked laptop be your favorite designer?

3D-blogging? People will be able to post vase designs based on how there feeling that day.

bobble heads or pez dispensers that are moulded after your 80 Auntie?

Will these 3D printers be the Amazon killers? Fed-Ex, UPS even cardboardbox companies will suffer major losses if these devices go mainstream.

Will "Over-Choice" become a major problem? How long will spend online choosing your daily coffee cup with the most current pop-culture reference? Will you hire a service to make your choices easier based on your profile? or will your printer make design choices for you.

how will this affect the 3rd world manufacturing

The economics of this are the biggest problem but, that can be balanced with against shipping costs, scale, labor, oil, pollution

Plummeting prices

Now Adrian Bowyer hopes to change that by making the first 3D printer capable of fabricating copies of itself, as well as a wealth of everyday objects. He reasons that prices would plummet to around $500 if every machine was capable of building hundreds more at no cost beyond that of the raw materials.
