Techniques for print ink droplet measurement and control to deposit fluids within precise tolerances
Patent number: 10950826Abstract: An ink printing process employs per-nozzle droplet volume measurement and processing software that plans droplet combinations to reach specific aggregate ink fills per target region, guaranteeing compliance with minimum and maximum ink fills set by specification. In various embodiments, different droplet combinations are produced through different printhead/substrate scan offsets, offsets between printheads, the use of different nozzle drive waveforms, and/or other techniques. These combinations can be based on repeated, rapid droplet measurements that develop understandings for each nozzle of means and spreads for expected droplet volume, velocity and trajectory, with combinations of droplets being planned based on these statistical parameters. Optionally, random fill variation can be introduced so as to mitigate Mura effects in a finished display device. The disclosed techniques have many possible applications.Type: GrantFiled: August 9, 2019Date of Patent: March 16, 2021Assignee: Kateeva, Inc.Inventors: Nahid Harjee, Lucas D. Barkley, Christopher R.

Patent number: 10137635Abstract: Functionally graded materials can be prepared through additive manufacturing by determining the path that a head of 3D printer can follow while extruding a material mix of a required composition at required points of a layer of an FGM. Each point within the layer is evaluated regarding the directions within which the printing head can move into from that point while extruding the material mix of a required composition. Based on the evaluation, a multitude of polygons are defined within the polygonal shape that are guaranteed to be printable. A path can be designed for the printing head to follow to print all of the defined polygons, and consequently, to print the entire polygonal layer. Material extrusion commands are generated for the printing head.Type: GrantFiled: May 19, 2016Date of Patent: November 27, 2018Assignee: Palo Alto Research Center IncorporatedInventor: Gregory Lewis Burton
