Comment on Europe's biggest 3D-printed building rises in just 140 hours
unexposedhazard@discuss.tchncs.de 8 months agoThe whole print process video is embedded in the article… www.youtube.com/watch?v=cfWryED7Zrk 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.

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.
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.

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.

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