Track motion

The track motion transports the BIG 3D-Printer along the U-axis from one job to another. The cutting unit for the reinforcement is being pulled along, the concrete pumps are stationary.

Cartesian system

The Cartesian System is a development consisting of a three- and four strap carbon rod truss with aluminium nodes.

It is mounted on the track motion and moves the print head with the upmost precision in the X- and Y-axes.

Advancement of material

The reinforcement is being transported to the Cartesian System via a conveyor system. The concrete material is being transported with concrete pumps to the print head.

Printing process

The print head which is attached to the Cartesian System stacks the concrete layer by layer. The required reinforcements for static loads are inserted to the robot between the printings of the individual layers. In order to give the concrete the necessary setting time, the printer moves to the next manufacturing sector, while the previously manufactured component grows numb.

The U-axis along the track motion is divided into different production sectors. With this system, finished components may already be outsourced while the printer is still creating the next components.

When the printer has printed the first component part in the last sector, it starts again in sector 1 with the printing of the second layer.

This process ensures that the existing layer withstands the pressure of the new layer.
