Machine Building
It is a weldment (on a robot) from steel pipes left as residual waste material in a company with production machinery for industrial production, destined for scrap for disposal. The client's assignment was thus an unconventional but at the same time creative challenge. Using several straight and bent tubes of a given length and radius and avoiding the use of other materials such as wood, design a new and usable product with a higher value than as waste material for disposal.
Implemented in one sample. The other material eventually found yet another use.
