You probably need "labor" just to set the machine itself up on the empty lot where the house is going to be "printed".

And then it needs to be disassembled and removed once finished.

I'm sure labor unions will picket these machines and throw stuff at them and scream profanities at them.

Even though the machines can do more in 20 hours than a whole team of construction workers can do in a week.

And the machine won't demand pay increases 24 hours after signing the building contract.

Cool idea, I think it'll likely cost more than he's predicting but may still be cost effective. However... he's dreaming if he thinks it wouldn't decimate the labor market for the construction industry. Loss of a lot of labor jobs and gain of a few high skill tech jobs (similar to the robotics industry).

Could you imagine the size of the block of plastic that would be needed. lol

nowhere does it explain even on their website how they plan on placing a layer of concrete vertically on top of several others while wet and expect it to stand on its own. See when cement is wet it has the compression strength of mud and doesnt like to stand up in a column without a form to hold it there. Partially dried cement doesnt stick to other cement very well and that's not good when youre looking to build a home out of the stuff. Their site makes mention of using piezo electric actuators and ceramics but im pretty sure a ceramic house wont be very sturdy in a hurricane or tornado.

The idea might work if you took this rig and enclosed it in a huge tub and filled that tub with resin and used a laser to heat up the resin like in a normal 3d printer. But as its designed now its a nice pipe dream but no it wont work for a home.

You can't "print" wiring & plumbing. I understand the concept, but it just doesn't work that way. Even if you could get the copper molten enough to flow, it's not going to just "stick" to the previous layer like resin does. To bond metal, both ends have to be hot, and pressure applied.

Assuming you used pvc for the plumbing and could effectively print that, there is still no suitable substitute for #10/#12 copper used to wire homes today.

The idea is essentially the same thing as thinking you can fly by strapping on a giant pair of wings to your arms and jumping off a cliff. Might look like cool if you've never heard of it before, but in practice it's just ridiculous.

A lot of construction workers will lose their jobs if this comes to fruition at a big enough scale. We can't use robots for everything, what will WE do for a living then? Have fun trying to remodel a home with concrete walls. This will make sense for low-cost or low-income housing, where the durability and low cost of concrete makes more sense. I will still buy or build a wood-frame home since that is what I like. Surely plenty of home-buyers will feel the same way.

You'd think outsourcing job is bad, wait until job elimination then you'd know what's bad. All labor jobs taken over by machines, no more low paying job or much less.

Imagine if one day people start printing cars. The big 3 stay in MI area and the plants around the country that probaly employ about 100k people or more would only need 10% of those worker to maintain and error check machines. Unemplyoment would propably go 40-60%.

[citation][nom]inerax[/nom]Wow.... wonder if this would lower the price of a home. Would the machine cost the same as labor?[/citation]

A possible faster way: Build per-fabricated material, then have the 3D printer put them together.

They essentially do this with slip form concrete.

Really the adoption of this wouldn't be a big issue. Just a few hurdles to overcome in the sequencing of the construction process. This would be an especially helpful setup for developing countries as you could setup a rail system the length of a city block and hit "print" and then go prep the next site while the machine builds each house in succession.

From watching the video I gathered that the machine will install--not print--the plumbing and the wiring as it goes. This is similar to what Thomas Edison attempted to do with his line of concrete houses, however this would be more adjustable in terms of layout.

It would terminate some jobs, but in the long run may prove cheaper and more sustainable than building wooden houses that are vulnerable to fire and weather. In some regions it will make more sense than others. A concrete and rebar designed house could withstand things a traditional framed house would not. Adding onto the house would be difficult, but this could change the lives of struggling families who want to own their own home, but can't afford to buy a traditional house.

Cazalan's an idiot. Housing prices are high because cities are zoning and also maintaining rent control laws. If Manhattan's rent-controlled free loaders (old people and welfare mothers who pay $300/month while their neighbors pay $2500) were priced out, the average renter wouldn't be paying $2500 a month in rent. We'd be paying $1500. And the price of housing would drop.

Supply and demand. Supply is low artificially because the building will not allow developers to build as much as the market demands. And also because whatever supply there is is partially taken by these welfare mothers.

Very cool idear though, I would love to own one of the smaller 3d printers.
