3-D Printer Creates Buildings From Dust and Glue
An anonymous reader writes "D-Shape, an innovative new 3-D printer, builds solid structures like sculptures, furniture, even buildings from the ground up. The device relies on sand and magnesium glue to actually build structures layer by layer from solid stone. The designer, Enrico Dini, is even talking with various organizations about making the printer compatible with moon dust, paving the way for an instant moonbase!"
I want a Fred Flintstone house.
Paying taxes to buy civilization is like paying a hooker to buy love.
Yes, but is it a solution to the problem of people replying to junk posts to get higher page placement? Putting things in context is a highly efficient organizational skill.
Beyond 2000? How about a Star Trek replicator?
Has anyone thought about the social implications? A Star Trek replicator would make real, concrete objects as easy to duplicate as intellectual property is now. We'll be in for a fantastic social upheaval.

Not paying, PAVING.
God do you people even think about what you're typing or saying when you use phrases like this? Did it ever once occur to you to think about what you're saying and how much sense it makes?

I get your point that insulation in home construction is very different from construction with moon dust, however I do feel like I should make this one point:
in practice of construction, there will always be some holes in it.
If there is one group of people that ought to be very talented at building things that don't have holes, its astronauts.
That's only true for a replicator that is unlimited. If the replicator had imperfections, what you say is nonsense.
Maybe cost of energy would be the defining criterium for the cost of goods (that would be about the same situation as today, energy input is the most highly correlated property to the price of a good).
If it was only able to re-arrange atoms you would still need mines to get to the necessary minerals, and many things would remain rare (e.g. you wouldn't be able to make gold jewels any cheaper).
If it required at least the same mass as input to create an object, that too would create scarcity, requiring again an economy (though probably different than today's)
The world would hardly be different, and we'd still need the economy to supply us.
