Methods of printing an object via a 3-dimensional printer include printing a shell and an infill structure. The shell defines an exterior of an object and includes one or more apertures enabling flow of a debinder solvent therethrough. The infill structure occupies a volume encompassed by the shell, and defines a network of interconnected channels. During a debing of the object, the network enables percolation of a debinder solvent through the structure and the one or more apertures. As a result, the object is debinded efficiently and in minimal time.
