METHOD OF CONCURRENTLY 3D PRINTING EXTRUDED PARTS HAVING DISSIMILAR SLICE HEIGHTS

Abstract: a method of printing a plurality of parts with varying layer heights in a single print job in a 3d printer includes providing a plurality of sliced 3d digital representations of a plurality of parts with varying slice heights in the z direction, positioning the digital representation of parts on a build platform of the 3d printer and determining a printing sequence of the layers of the parts based upon a lowest z height between the plurality of sliced 3d digital representations. the method further includes extruding the layers of the plurality of disjoined parts with one or more print heads based upon the determined printing sequence and intermittently indexing z height between the sequenced layers until each of the plurality of parts is printed.
