AI Technical Summary

Problems solved by technology

When one or more nozzles become clogged, those nozzles are no longer available (i.e. disabled) for depositing build material, and the entire printing process can be severely affected, reducing the print quality of the object being built
In most cases, a damaged printhead will need to be replaced to restore full functionality to the printer, and if replaced frequently, overall printing costs can be greatly affected

Abstract

Methods and systems (100) of printing a 3D object (101) comprise: depositing material, layer by layer, via printing heads (72) comprising one or more nozzle arrays; and activating each of said printing heads (72) to dispense a building material (50) at least once within a specified period of time during printing.

Description

[0001] related application [0002] This application claims priority under 35USC 119(e) to U.S. Provisional Patent Application No. 62 / 784,852, filed December 26, 2018, the contents of which are incorporated herein by reference in their entirety. technical field [0003] The present invention relates to the field of additive manufacturing (AM), and more particularly, but not exclusively, to systems and methods for improving the reliability and lifetime of 3D inkjet printheads for three-dimensional (3D) inkjet printers. [0004] Background of the invention [0005] Additive manufacturing (AM) is a technique capable of fabricating structures of arbitrary shape directly from computer data through additive forming steps. The basic operation of any AM system consists of slicing a 3D computer model into thin cross-sections, converting the results into 2D positional data, and feeding the data into a control device that fabricates the 3D structure in a layered fashion. [0006] Addit...
