3DION and voxeljet completed a replica of the Cologne cathedral

The 3DION 3D network, together with its partner voxeljet, one of the leading manufacturers of industrial 3D printer, implemented a prestige project for Cologne Cathedral.

Replicas for the patrons of the Michael portal were produced in collaboration with, and with the excellent support of, voxeljet. The Michael portal is one of nine portals with a total of twelve doors, based on the gates of ethereal Jerusalem from the Apocalypse, in the image of which the cathedral was created.

On 21 August 2015, the Zentral-Dombau-Verein (central cathedral building society) and the Kölner Dombauhütte (Cologne cathedral workshop) invited around 100 benefactors, who had become patrons of the restoration of the Michael portal, to attend a mass with cathedral provost Gerd Bachner in the inner choir, followed by a small celebration in the stone restoration workshop of the cathedral workshop. It was to thank all of the patrons for their generous commitment to the restoration of the portal, which was heavily damaged by the war and weathering.

3DION convinced the former master builder Michael Hauck, his deputy Peter Füssenich and ZDV president Michael H. G. Hoffmann with the recommendation to have replicas of the figures made by voxeljet, since their material most closely corresponds to the haptic experience of sandstone. The Southern German company is one of the world’s leading providers of industrial 3D printing technology. With its own service center, voxeljet offers the on-demand manufacture of sand molds and plastic models for many different industries around the world.
