Patent number: 11701830Abstract: In example implementations, a method for extracting layers of build material into a carrier. The method includes providing a layer of build material onto a bed. Portions of the layer of build material on the bed are digitally printed with a liquid functional material (LFM). The method repeats providing the layer of build material and digitally printing without applying energy to the LFM to define a structure in layers of build material on the bed. The layers of build material are extracted into a carrier and the carrier is removed.Type: GrantFiled: January 5, 2021Date of Patent: July 18, 2023Assignee: HEWLETT-PACKARD DEVELOPMENT COMPANY, L.P.Inventors: James Elmer Abbott, Jr., David A.
