Additive manufacturing of tiled objects

Abstract

Objects and methods for the manufacture of objects are provided such that the manufactured objects comprise a plurality of tile pieces and seams between the tile pieces, the seams allowing for controlled breaking of the objects. In some embodiments, the objects comprise casting molds or mold parts comprising a tile structure.

What is claimed is: 
     
         1 . A method of manufacturing a mold or a mold part, the method comprising:
 providing a three-dimensional (3D) representation or model of the mold or mold part;   identifying one or more areas of the mold which are expected to be difficult to remove from the casting;   meshing the 3D representation in the identified areas to create a 3D model of a partially meshed mold comprising one or more mold parts, several tile pieces, and spacings between the tile pieces; and   manufacturing, according to the created 3D model, a mold part comprising several solid tile pieces interlinked through seams, wherein the nature or size of the seams is such that their strength is reduced compared to the strength of the tile pieces and mold parts.
