Tasked with building a new data center in an urban area of Germany, the team behind the Wave House harnessed the benefits of 3D printing technology to inject a sense of style into the unglamorous world of cloud-computing infrastructure, creating Europe's largest 3D-printed building in the process.

It really is just a big 3D printer. At first i thought the walls were like 90% air with no infill but it looks like they fill them up with rebar and cement.
So really its just a thing that prints unique molds to pour concrete into so not really “a 3D printed building”
Thanks, but I more meant specifics, like what is the “cement-like mixture”, what extruder they are using. If it would be possible to DIY this basically.
There are several companies doing 3D printed concrete. It generally is concrete, just formulated and mixed for being piped and coming out of a 4" nozzle. Ifyouu search YouTube you can find more detailed breakdowns, but the principles are the same as desktop FDM, just scaled way up. That said, don’t expect to be doing this in your backyard unless you have heavy equipment and large scale building tools laying around.
This guy DIY’d it way back in the early days of concrete extrusion. He actually let a college class I was in see it. It was definitely an involved project and the result was pretty rough around the edges. His system was pretty slow and took a substantial number of batches to complete. Getting the machine and mix balanced for extruding all in one go would be pretty difficult and you’d probably need to have it mix continuously rather than in batches.
Unfortunately I don’t remember much about the type of mix he used or the pumping system. So I can’t guide you in the right direction.

Oh and you also need a decently sized stone crusher for all your failed attempts and speedbenchies.
