@buildybryce: 3D Printed buildings are cracking...

Brandon Ackerman :

if we used Roman concrete no cracks would appear since it's self repairing

Crazybrutus :

concrete always cracks

Carlson508 :

They need to add a fiber to the concrete

WokingSmeed :

“Concrete cracks” okay so should we be making our houses with it then? Probably not..so what’s the point in saying it the way yall are bro

American🇺🇸🦅😎❤️⚡️ :

People are the only problem

Let’sSipSom :

I don’t get why they can have a smoother come along and make it smooth instead of dog this line by line level

Bill Herrera :

Concrete cracks buddy. Nothing new.

b1gnate08 :

if we could finally crack the full recipe to roman concrete I feel like that's the missing key to 3d printing houses

⚡️⭐️Alsmyth⭐️⚡️ :

hold on let me pretend to be shocked real quick

robc0255 :

there is absolutely no need to "3d print" concrete. we can already use forms to mold things. i could have pured this house for half the cost and it would be fine. they have full wall forms that can be removed, insulated blocks that can be formed ect. this is by far the dumbest use of technology.

E :

The problem with 3-D printed houses is there is no reinforcement to keep that cement from cracking that isn’t why it is not a good idea to get a 3D printed house

jeff :

doesn't sidewalks and driveway need expansion joints so should the 3d prints houses right

Dyslexic-batman :

To be fair I was touring newly built houses last year and all the houses I looked at had cracks on the outside and some of them had foundation settling cracks on the inside too

Tuxydoh :

Try leveling the bed 😁

Blackoutwhyte3566 :

There is a difference between cosmetic surface cracks and deep, concerning structural cracks. That why there are expansion joints in sidewalk, so the concrete can expand and contract

aphillips450 :

there's only 2 kinds of concrete. concrete that has already cracked, and concrete that has not yet cracked 😅

Aker :

No seal coat, no paint protecting the concrete, no plaster to smooth it off and protect it. Exposed concrete cracks when its load bearing, moisture is no joke 👍

Just cover it in the same stuff used in OTHER houses to not let concrete crack

Z1-Mimic :

feels like it need a exterior layer of concrete to protect the intore portion and flattens it out It might just be me but the edges and bumps collect water causing it to decay faster

Sam Ferree :

That’s not generally true. The market value of lower quality houses is lower. Nobody would buy $300k 3d printed house if a brick house the same size is also $300k

T2qW8mK4xR9vLp1Nc7Yh5Dz3Fs6JgB :

As if drywall and flooring doesn’t crack in any new construction

mrengibeer :

first, the tech behind extrusion printing buildings wasn't marketed to be used in expensive markets, it was originally intended to rapidly manufacture single floor homes in underdeveloped or in need areas. second, the tech is still under development, and this is clearly showing why it isn't fully deployed yet. these kinds of defects could probably be overcome with different site prep, concrete blends, or other strain relief features, but more experimentation and time seeing what kinds of failures may occur is needed. this isn't proof it can't work, that's not how engineering new tech happens.

Johnathon Parsons :

I feel like there is not enuff re bar in the printed one. even pored concreat walls have reinforcements
