Abstract
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.
Claims9
A method of printing an object, comprising:
- printing a shell defining an exterior of an object, the shell including at least one aperture enabling flow of a debinder solvent therethrough;
- and
- printing an infill structure occupying a volume encompassed by the shell, the infill structure defining a network of interconnected channels, a cubic subset of the infill structure enabling percolation of the debinder solvent from any one face of the cubic subset to any other face of the cubic subset via the network of interconnected channels.
