Abstract
A method of additive manufacturing an object featuring properties of a hard bodily tissue, comprises: dispensing and solidifying a plurality of non-biological material formulations to sequentially form a plurality of hardened layers in a configured pattern corresponding to a shape of the object. The method forms voxel elements containing different material formulations at interlaced locations to provide a three-dimensional textured region spanning over the portion. The material formulations and the interlaced locations are selected such that the textured region exhibits, once hardened, a stress variation of at most ±20% over a strain range of from about 0.1% to about 0.3%.
