This is probably a expensive exotic concrete mix, what is the price of a 1m3 of the printing material. And probably some sort of accelerator is added to the mix for it to set quickly. You should add %0,5 - 1 graphene oxide and %1 basalt fibers (not more than 1cm long) both materials must be in some kind of water suspension and mix well with concrete mix. And print a dome structure as big as your machine supports. ASAP :)
The video looks too cool. The printable material looks perfect since the stand-off distance is almost invisible and the deformation for the bottom layer is really small. Have you measured the global deformation during the printing process?
We did not measure the deformations during this experiment. In fact, we didn't expect the material to be this good :-) The week after, we printed a column of 3 m in 11 min :-) We think we can go even higher. More detailed investigations are currently being carried out. We hope to provide you with some updates soon.
@@Concre3DLabGhent Thanks for your awesome work. By the way, when you design the g-code for printing, did you consider the deformation of the printed layer?
Great if you need an unreinforced concrete column that is gawd awful ugly So called 3 D printing solves a problem that doesn’t exist while creating 100’s of new ones that are unnecessary
The problem is not about making unreinforced concrete columns. It is about increasing design freedom for concrete constructions and automated production in an industry that is defined by costly manual labor. Nevertheless, you are right in the sense that the technology at this moment is not yet completely ready for mainstream adoption. But, I have seen 3D-manufactured objects that look exactly like cast ones. time will tell...
@@Concre3DLabGhent I agree that, with a lot of work, you can make it look presentable After that you can address the lack of appropriate reinforcement and insulation I have patented methods and materials which are faster, do not require huge up front investment, and do address what is needed for proper building health and safety

incredible that it doesn't collapse under it's own weight. It looks pretty wet so that it doesn't clog.
Rheology and set are no longer limiting factors.
Very interesting video... Thanks. Any idea where I can buy a ciment 3d printer for building prototype

It is not that exotic as you might think. It might cost about €150/m³ of raw materials in bulk. Thanks for the suggestions.

@@zechang1935 No, but it is a very cool idea that could be implemented.
Just need a way for reinforcement
Hi want to know no about mix design and which materials we have to use in it.
M more impressed that it did not collapse. Can any one give me a good scientific explanation for this? I'd be grateful
We have exceptionally good hardening over time.
@@Concre3DLabGhent can you explain on the immediate effect, and not over time.
@@jatwangismyname900 That immediate effect is part of a patent application, so unfortunately I cannot tell you much about it
@@Concre3DLabGhent Okay

@@teslastones I wish you all the best.
@@Concre3DLabGhent thanks. ( I have it )
