SYSTEMS, DEVICES, AND METHODS FOR THREE-DIMENSIONAL PRINTING

摘要

Systems, devices, and methods for three-dimensional printing are provided. The systems, devices, and methods provide for high throughput printing by allowing for parallel extrusion within a single vertical layer of the printed object, i.e., parallel extrusion within an x-y coordinate plane. Any advancement of an extruder can be limited to movement along a single axis, or even no axis at all, so that printing occurs more quickly. In some embodiments, the extruder can include a printing plate that includes a plurality of apertures defined by conductive elements extending in a grid-like manner. The printer can be designed such that material is disposed to a build platform through the apertures only when the aperture is heated on all four sides, for instance by running current through the conductive elements that define the aperture. Other systems, devices, and methods for three-dimensional printing are also provided.

1. A method for printing in three dimensions, comprising:
printing a first layer by near simultaneously depositing material in a plurality of locations within an x-y coordinate plane of a first vertical level; and printing a second layer that is disposed vertically above or below the first layer by near simultaneously depositing material in a plurality of locations within an x-y coordinate plane of a second vertical level.
