3D PRINTING | PERI 3D Construction Printing: Europe’s largest 3D-printed apartment building (EN)

Fabian and Yannick from the PERI 3D Construction Printing team provide insights on:
- The 3D construction printing planning process
- How to operate the printer
- How various trades can be integrated into the printing in order to save time and costs

It is the greatest thing that peoples can do and make more faster than construction by worker.

[@bcsurf7]

Peri, Winsun, Gaia and Icon have some great ideas. They will definitely be key players in 3d printed homes, stores, warehouses, waterways, and pretty much anything to do with building 3d structures. Hope you make it to Florida US. We need all of you.

Thanks for the info. Are you an investor ?

[@movax20h]

Could you make less hyped video, going more into details, technical stuff, material delivery, what accommodations to the plans were needed, insulation, reinforcement, overhangs, attachment of windows and doors, etc.

Ich will so einen Drucker!!
Würde aber auch investieren

Why not just build a machine that can put cinderblocks? Way less of a set up, the technology is there, you don't have to worry about cleaning any pipes, the finish product can be considered cosmetic, prefab concrete, I can keep going...

[@rablobanda]

well, it does not look as good as you describe it. i see the point of 3d printed (temporary) buildings, but this process design looks far from being finished and usable.
first of all, you probably spent more time to prepare the construction site compared to the "classic" way (there's not just a crane, but 2 oversized support stands and everything else). the foundation of the building was probably made the same way, so you needed the old fashioned machines.
in a "classic" construction the pump fills a whole wall with concrete in one step. this concrete-printer uses way more fuel to move the printer-head around the building just to put on a 1-inch layer - while a full height wall is more than 100 layers...
and where are the reinforcement bars? will they go in the hollow parts of the walls, then you'll fill them with concrete? then you'll need the same old fashioned concrete-pump as well.
the only difference is that you spend weeks to print a mold, instead of building a sliding formwork in a day. then put in the rebars, and fill the void with concrete... (without reinforcement this printed material wouldn't be strong enough in 6 days to build a new floor above it. so it's not an advantage.)
and obviously you'll need to work a lot on the interior walls to make them usable. the raw surface can look good on certain areas of a home, but it's not ideal everywhere.
there is no real advantage of this technic. even if you want to build something on the moon or anywhere without construction workers, it would be better to design robots who can build the sliding formwork.

Very good points. Though, digitally-controlled construction is inevitable. Keep in mind that they are truly concrete forming experts, so they will figure out how to do this in a manner that makes more economic sense: Use of low-cost locally-sourced conventionally-reinforced concrete that meets codes, and avoiding any need for that expensive protection structure. You suggestion of digitally-controlled sliding forms is excellent! You could even get a finished surface that way, based on the digital model.

The preparation time won't be longer than on a normal construction site. Instead of building a mold and supports and repeatedly move them after each cast, which takes a lot of manpower, you just build the printer and let that move on its own. Man hours are the main reason building is expensive. Also the electric motors won't take that much energy since they don't move at extreme speeds.
Btw the printing process takes days, not weeks. The rest of the time is used for electrical installation, filling the voids with insulation, adding doors and windows and plastering the walls.
Regarding the reinforcement. I guess up to a certain height, you probably don't need much rebar and you can see, that they put in horizontal reinforcement to keep the walls together. Rebar is mostly necessary for bending stress but this building is only 2 or 3 storeys tall, so it is mostly a compressive load.

Dear CritiCube,
no reinforcement is required for the displayed application.
We would be happy to answer any additional questions you might have. Just contact us at [e-mail].
Kind regards
