well he can spread cement. Hardly useful but many hobbies aren't either, at least he learns something.
True, but - "In real life, during the house building process, I need every layer to start with the homing procedure. This is the only way I can know that the printer did not shift due to wind etc during the procedure and the house isn't crooked."
It sounds like he is actually trying to spread mortar (not cement) onto CMUs, since he's worried about "crooked".
Two different consistencies, two different products.
And then there is no compensation for different wetness (fluidity) of batches.
And then loading into the machine.....
2cm (3/4") nozzle ................
Electric motors for pumping......(there's a reason why all cementitious pumps in the industry are hydraulic (or pneumatic) cylinder based)
Not worried about temperature of the product, which
is a factor...
And the topper - "construction codes in the US are very strict; it is very possible that I might have to build my first real printed house somewhere in another country."
What he has laid out is not even suitable for ornamental cement castings, much less something structural.
I really feel sorry for the guy, as it seems he has no real world experience with what he is trying to accomplish.
I mean this is like a plumber assuming he can weld, because he knows how to solder :whiste:
