I saw one of these construction sites in my town for low cost housing. The system is incredible to watch. The thing that got me was the amount of labor people needed. It looked like the regular amount of labor used. It amazes me how fast the structure went up. 5 one bedroom houses in two weeks.

@tripives1858 Год назад

If you've never built a home... Additive printing technology is a cool concept for home construction. However, there are a few things to know if you've never built a house. First, the exterior of a home always goes up in a matter of days or a few weeks depending on structure size and crew size... regardless of the technology use. For example, if I use SIPs (Structural Insulated Panels), I could standup all exterior walls in a day or two and frame and frame and sheath the roof the next day. Second, the exterior covering (stucco, clapboards, etc.) gets added to the concrete/sheathing/cinder blocks, etc., followed by windows, skylights, roof covering, etc. Before that you typically Tyvek/seal the outside of the house. But again, all of this is done within the first few days or weeks. It's the inside of the house that take months... electric, plumbing, HVAC, insulation, drywall, taping, painting, finish carpentry (kitchen, bathrooms, flooring, inside doors, floor moldings, window moldings, door moldings, crown moldings, etc.). If your walls are concrete, all of this work is much more difficult, or, you need to take additional steps before drywalling. The point here is that, while cool, 3D printing your walls will not save you time, and, at this time, actually costs more than the alternatives.

@dandan6778 Год назад

@forcedindenturedservant6881 Год назад

Plumbing would be run in the slab, radiant heat in the slab, hvac in the ceiling. You don’t need to drywall but the electrical would need to be in the walls. I’m a builder and I agree with what you said, you just might have to look at different methods on these than a stick built home. I think it would end up costing more but with the price of lumber lately who knows!

@jackchandelier Год назад

I was thinking the same thing. This doesn't seem to really save any time - when you factor in all the set up and everything - or labor. And then the finished product is butt ugly and much more difficult to work with. Probably not that much cheaper either when you consider the extra work involved in working with concrete vs wood.

I never see any rebar. Isnt it necessary for the strengt and duration of concrete?

@lorez201 Год назад

Rebar as I understand is meant to provide tensile strength to concrete, and since the wall structures are likely only experiencing compression, rebar isn’t as necessary in them as in, say, an overpass or the concrete frame of a high-rise. Also, I think earlier in the vid they show some small pieces of steel crossing the interstice of a wall. Those might be what they use to maintain tensile strength where needed.

Not required but certainly a stronger way to build

@Enjoymentboy Год назад

When I first heard of this idea years ago I thought it was very intriguing. Seeing it in action makes me see the benefits but I was surprised to see that its use appears to be limited to outside walls. I would be really interesting to see the whole house structure built this way: inner and outer walls together. Just start with a level base, start the print and have the on-site crews installing things such as rebar and electrical or plumbing access ports as it goes, followed by a different crew coming it to top it off with a pre-built metal roof. Then seal with PVC windows and fibreglass doors and finish the walls with plaster and PVC trim. Zero wood used. But i really like this concept.

@sethjayson7235 Год назад

Not likely to happen. A 3d printer thowing lines of plastic can achieve an overhang because the layers bond quickly and stick, and the lines are thin and light. A dome must be self supporting on the way up if it's built without centering, meaning at a minimum you need to each circular level supported. Tough to do that with a thick glop of concrete.

Can techniques from plastic 3D printing be used to form non-flat tops of doors and windows? Maybe take inspiration from Roman concrete and stone buildings to make self-supporting arches or overhangs, then mass produce windows and doors accordingly. For utility savings reserve the space between the two outer layers for loose fill insulation material, hanging pipes and cables inside the building for easy access and repair with basic tools.

We built with ICF and it has a lot of advantages over 3D printed concrete. For example it has studs embedded in the styrofoam at 8” intervals inside and outside. One advantage of the 3D printed concrete is the thermal mass that’s inside the house. With ICF, the thermal mass is within the wall between the styrofoam insulation layers.

This is for incredibly cost efficient, short term housing. These homes are not going to stand the test of time, nor are they designed to. Not a great choice as your next home.

@PalmettoNDN Год назад

@@johnd9357 wrong on both fronts. It is not incredibly cost efficient because of the cost of concrete, but it is cheaper than lumber and labor. Second, these are every bit as strong as wattle and daub - which is the construction method for all of the contenders for the oldest houses.

It looks ok , but where is the rebar , after years of wind and rain , you would have wanted some rebar in that wall. Rebar is round long iron rods that add the strength to a wall or/and foundation . Rebar is in all and every building in NYC . Looks like it would be great to watch and take part in a real build . Mike .

@electronicscaos 2 года назад

I'm not a big fan of it, because this process isn't actually that efficient (molded structure is far better). But there are two replies to your question: this kind of construction allows more solid overall structure to be built, since you can calc the curves and formats to strength, allowing to reduce a lot the needed iron (I read there can be something around 80% less iron in this 3D printed builds), but there is iron applied during the printing anyway, from the ground up. Again, I don't think this is the best way of building... But there are some niches where it fits perfectly.

Rebar isn’t needed for loads for houses you have fiber, which this concrete does.

You could add some colored powder for some color. Another idea is to build up interior and/or exterior walls to cover the concrete.

The thing about 3D printing with concrete like that is that there's no rebar supporting it. It wouldn't be nearly as strong as reinforced concrete.

@@L0stEngineer I do not know you have a lifespan of buildings, but in our regulatory documentation, the lifespanof concrete buildings is from 50 to 100 years, depending on the brand of concrete.

@L0stEngineer Год назад

@@dimarium that's for reinforced concrete with steel rebar. Eventually, the steel will rust and crack the concrete. If it's unenforced, it has no resistance to tension, but may last a whole lot longer.

Right on observations here. Best of both is to reinforce the "wall" in protected space, and put no steel in the outer, with lots of insulation and drainage in between.
