The perfect copy ofa historic monument

It was an unusual request for the voxeljet service center: Printing 100 sand molds at sizes of up to 1.5 cubic metres. This large order is related to the reconstruction of the historic Liebknecht portal – a very unusual project, as two versions of the portal will now be located in Berlin in the future: the original in the former Privy Council building of the former German Democratic Republic, and a 1:1 copy in the Berlin City Palace that will be built.

The idea behind this unique project: A desire to retain the originality and historic significance of the Privy Council building, while at the same time bringing the Liebknecht portal to the new palace – a project that can only be implemented with a copy that is true to the original.

The subsequent generation of the physical models in 3D printing was now the task of the voxeljet service center in Augsburg. After looking through the data, it became clear how extensive and complex the print job would be:

The result of the innovative copy process met the expectations of all those involved. The copy of the historic portal is geometrically undistinguishable from the original. Print quality, precision and detail of the sand molds are beyond any doubt thanks to the impressive high-performance of the VX4000 3D printer. Now it is up to the sculptors, who use the 3D print as a template for their work, to sculpt a perfect copy of the Liebknecht portal in sand Stone.
