Abstract
Concrete columns, in almost every shape, can be created by concrete printing. The formwork will be printed and subsequently filled with traditional concrete. Within this research, the influence of concrete printed formwork on the load bearing capacity of a printed column is determined. The research is performed on a small concrete column, from which is concluded that the difference in shrinkage between the two types of concrete has a large role within the occurring stresses in the element. This means that the relative shrinkage determines the load bearing resistance in a small concrete printed column.
