Isn't the hemp concrete not supposed to be load bearing? Isn't the who point of 3d printing to be able to make small, customized/unique parts that you only need a few of? All the components needed to build a house are relatively cheap manufactured goods.
Why did 3d printing a house sound easier or cheaper than just building a house in the first place?
I read an article about this a while back. IIRC, they could build the foundation and walls in just a few hours using special concrete and 3D printing. Cheap materials, minimal labor, fast production time = dramatic cost reduction.
Good point if they can do it successfully in just a few hours
The rest (windows, doors, plumbing, wiring, flooring , etc) still need to be installed after the 3D shell is made/cured.
Yes. Hempcreate is supposed to be used between the interior and exterior concrete walls because it's insulating and less expensive (can be mixed onsite). This combined with rebar allows it to function for purpose. Because the exterior layers of concrete is bearing the load around the hempcreate and the reinforced hempcreate provides rigidity and anchor to the foundation, it's complimentary. Which saves money on the fill and is also insulating. In turn, removing the hemp from the weather and expansion cycles. The expansion cycles, I'd guess, would be the point of failure of any attempt to directly use it solely structurally.
I had no idea anyone was using it for the entire structure.
Well I can assume this hemp crap mix is cheaper than concrete, wood, drywall, vinyl siding, etc, plus eventually you could automate the "printing" and mass produce the hell out of it.
I wonder what the insulating properties of this "hempcrete" are. There's probably some horrible drawback to this, but it would actually be great if the execution of it was good (extreme doubt reserved).
Yep framing is white man's work for a white man's wage, it's tedious, skilled labor that takes time and prep, if you can just print walls and supports with a million dollar rig one technician and three spics shoveling print material would be cheaper in 90% of the US market in a year or two.
I see the value in it - low-cost housing that just isn't possible anymore. True, it's treating a symptom of the wider jewconomy, but Whites developed the technology...
The components to build a house might be cheap, but if you can't do the work yourself, building a house suddenly becomes not cheap.
That's why they want 3D printed ones. You don't need white men to frame your house, if everything that comes out of the printer is square and just snaps together. That's why.
