ive sent the an email the good thing that they reply fast
https://youtu.be/3VuS8ppiEwc they have sent me this video and they say the could build on custom size as i order the only thing the extruder look too small for printing a building the only thing i couldnt figure it out is it continuous flow of cement or it stops in some place and if im building one how i can control the concrete pump to stop pumping on the specified areas if theres any one with experience in controlling the concorete pump through the controller that would be very helpful.
and for the BetAbram ive sent them an email like a week ago still no reply from them if you know how to contact them or if i can get a quote for the 3D printer and how to order it
Thanks alot for the reply
