Abstract: In a method for repairing or modifying a modular concrete block mold having multiple mold parts, a replacement mold part for a mold part to be replaced of the concrete block mold is additively manufactured and the replacement mold part is installed in the concrete block mold in place of the mold part to be replaced, or a region of a mold part to be adapted of the concrete block mold is additively manufactured and the mold part adapted in this way is then installed in the concrete block mold.
Abstract: A mold part of a modular concrete block mold has an additively manufactured region or is an additively manufactured mold part. The additively manufactured region may be a 3D metal printing region or the additively manufactured mold part may be a 3D metal printing mold part. The mold part may have a milled or cast region and the additively manufactured region.
