PortaPrint / A mobile 3D printer


PortaPrint is a mobile 3D printer that prints as it drives around. It can print without CAD - using vision control to follow and extrude on top of lines drawn by the user. This solves two limitations with FDM 3D printing - the print size limit imposed by the bed dimensions and the CAD skill requirements.

PortaPrint has the potential to be scaled for use in the construction industry. This would greatly reduce material waste, due to the increased precision and automation offered. Furthermore, it would reduce the labour intensity, thus the risk of injury in a very physically demanding role, and does not need extensive training to operate.
