No, properly made buildings do that.

Well, since the average person does not know how to detail and build structurally sound tilt-up construction, regulations are an effective tool to ensure that buildings are made properly.

I think there is a good case for a system that doesn't rely on the immoral practice of appropriation to obtain those ends. Just because it is doesn't mean it has to be.

Like I said, if you can come up with another method, I'm all ears.

You are already discussing it in another thread. It is also off topic for this thread.

Concrete is a good construction material. This will save so much time and money. We have a block of land in the dinaric alps, 30 of these as weekend houses would be a godsend.

Still, it's one thing to 3d print a small house out of concrete, or even make a concrete house from a single pour mould. It's quite another thing to make a concrete house with central HVAC, wiring and plumbing. They're basically making bunkers, not houses.

Given some high altitude climate conditions, bunkers are useful.

Nothing stopping you from adding that later, as with all construction. The most troublesome elements are always the walls and the roof.

The lack of insulation is a problem.

This does not create the walls and the roof. At most, it creates the structure, and you can then use this to support the walls, roof, doors, windows, waterproofing, services, finishes, millwork (or casework or built-in furniture or whatever you call it), equipment, lighting, etc. that also are part of a house.

The main problem with modern 3D printing is that you only have one material in each printing.

The applications are amazing. I don't think it's over-hyped.

What commonly gets overlooked about 3d printing (for the average person) is that it can be extremely useful for printing one-off parts that will allow you to modify or repair the things you use every day. Take this example:

a man broke the lock on his car door, and instead of going to his dealer and paying $250, he printed out the part he needed and fixed his car in a few hours for almost free.

It might be a little complex for someone who isn't a tinkerer, but you don't have to be a genius by any means to do something like that.

It sure doesn't look over-hyped, to me.

I don't think it is really overlooked as such. It's still fairly new, and it requires some technical skills to draw 3D objects, even if it is just using sketchup.
Decent printers are still fairly expensive too but that will continue to come down as quality goes up (the market at its best).
I guess the term over hyped is quite subjective as well, but in terms of significantly decentralizing manufacturing it is over hyped. In terms of individual users making custom parts or the ease at which R&D firms can save money and time on prototyping (including small startups) it is not over hyped.

the discussion on bioprinting of human cells for research purposes (testing new drugs on live human tissue)

A not to be underestimated application as well, also don't forget printing out collagen scaffolds for creating transplant organs. Cells are tricky to work with however, especially stem cells, so there is a lot of work to be done on the 3D printing thereof.
