@beka_valentine #Prefab requires more logistics, tho the #cement to do *" #3Dprinting of houses ain't lightweight nor easy to carry either...
The main advantage would be that the latter could be solid, longer lasting and have better thermals but that's disputeable if not questionable and in regulated places like #Germany all #housing has mandated #insulation and #FireSafety standards...
@kkarhan @beka_valentine pre-fab is superior to pretty much everything else, *except* individualization. And even that's been largely solved through individualization at the factory.
To me, there's also a bit of classist "that's how places for poor people are built" in the anti-prefab messaging.
The precision of 3D printing can move pre-fab quality to the site, but it's still worse in parallelization, drying times (you have only one place, not twenty), and surface quality.
@kkarhan @beka_valentine prefab also allows for large scale support and handling (think ceilings, moving scaffolding, etc), for higher paid and more specialized people to work on an aspect repeatedly, and for placing large amounts of inlays such as cable ducts and rebar.
Space is a major concern at construction sites, factories can reuse the same space over and over again.
What 3D printing allows is better pre-fab or moving part of what's essentially pre-fab closer to the site, though.
@RichiH @kkarhan @beka_valentine
I think the house I grew up in was essentially a 1900s prefab house - a catalog house, where you'd order a package from the factory with every board pre-cut to the right dimensions, every pane of glass the right size, the right amount of wiring and light switches and door hinges and banister posts and plumbing parts, all shipped to your construction site in one lot.
@dragonfrog @RichiH @beka_valentine personally, I wished some company would do prefab micro apartments in 20' & 40' containers (whilst also retaining the structural stability & corner castings for ease of installation and stability) and just build some stable, cheap housing block 9-20 + levels high.
Maybe put like garages, bike racks and storage at ground floor, add an elevated platform with shops and restaurants on the 1st floor, offices and doctors on the 2nd and then 3-9/-20 with cheap housing!
@kkarhan there was a company doing something like that but it turns out to not be all that good of an idea for some reason
