That might (sadly) be a product of our times:

1. Some interesting topic (3d-printing) pops up
2. People reuse that information on their ad-monetized platform.
3. profit…

I don’t think the manufacturer will publish those numbers.

On the peri-website, there are some numbers relating to printing-speed, layer-thickness and -width and setup-times (english / german). With those one could calculate approximately how long it could take to print a certain building in optimal conditions.

More than that you will probably not get out of them.

Unfortunately, I couldn’t really find more information. All results of a web search about this project in this state seem to be the same press statement almost copied verbatim.

My comment was no dig at you for choosing that article. 3d-printing is kind of interesting and with the scale of printers needed here, there will not be a lot of independent information very soon.

But I’m glad there is some public focus on construction methods, even if the “recent” developments in construction that I personally think are good for future-proofing the industry and reducing CO2-emissions (like increased use of prefabrication even on smaller scales and more use of wood on larger scales (e.g. cross-laminated-timber) are not that “interesting” to the public.

As a civil engineer I see the whole 3d-printing-buildings-thing mostly as a gimmick and a way to grab some research-money to co-finance your building. At least at the moment.

In this case they still added timber-framing above the concrete walls and as interior walls and roof, so one couls ask why they wouldn’t build the whole walls as timber frame. That would be faster for sure.

But of course not every building has to be built fast or cheap. There are other valid criteria…

And it’s ok to try to find new ways to build walls - even if thats a part of construction that can be done quite fast & efficient already via prefabricating.

Concerning the article:

The author seem to have taken the press-statement from the 3d-printing-company and subtracted some pictures and the metric units.
Without transparency about costs per m² compared to other construction methods it is just an advert.

There is a picture on the architects website that shows, that the walls do have internal insulation.

But there is stillvery rough exterior concrete, which will look brand-new for at least until it has rained 10 times.

And yet he is the formal head of state. Which was all I said.

Just to be correct: You are probably referring to the Chancellor (Merz). Thats the head of the government.

The head of the state would be the president (Steinmeier), who - as far as I know - has not expressed such rhetoric.

How usual is it to have a “disturbed” gps-signal around Russia?

I was near the russian border to Kaliningrad in Lithuania in the summer and 2 of our 4 GPS-devices were “all over the place” on that day. Constant location-jumps, sometimes no location at all.
