My reaction is that the results could be more easily achieved with existing
technology. It would appear easier to print, or cnc, a mold, and then pour
the concrete. this would help with several issues: 1) the concern about
concrete hardening is the printer; 2) the finishing of the final product. It
would be much easier to achieve a smooth surface on the negative, than on
the concrete, and 3) the need to engineer and manufacture the "printer".
In other words, if I had to make these parts, i would probably cnc foam,
in layers, finishing the surfaces as necessary, then pour the part. The foam
could be easily removed after the concrete cures. The other advantage of
"my" technique is that the significantly lighter mold could be transported
to the construction site and then the part could be poured there.
It is very likely that you've considered this technique and have reasons
why your process is better--and I am curious as to what these reasons are.
