Abstract
Multi-material, three-dimensional fabrication is improved by the use of a purge wall adjacent to an object to absorb transitional artifacts of material changes. The structure of the purge wall may be selected to reduce build time, and to reduce certain printing artifacts such as warping and delaminating. For example, alternating layers of offset or mirrored zigzag patterns may be used to reduce and distribute the layer-to-layer adhesion surfaces throughout the purge wall while providing sufficient contact points to maintain the structural integrity of the purge wall.
