Thank you CPT worldwide for this great feature. Concrete printing is developing so fast and CPT magazine is the go to source to stay up to date.
Calling on all architects who see these columns supporting one of their buildings. We print the shell - it is filled with traditional concrete and the print serves as permanent formwork.
Fun fact: the column in this picture is upside down. It is actually wider at one end for material reduction of flooring systems.
Props to our robotic fabrication engineer (Kees Leemeijer) who designed the columns. This was a great Friday afternoon print that turned out to be stunning.
