Publication number: 20230347664Abstract: A printer includes a substrate support, a printhead assembly, first and second actuators, and a controller. The printhead assembly deposits material on a substrate supported on the substrate support. The first actuator is disposed at a side of the substrate support and coupled to a first linear track disposed along the side of the substrate support and oriented in a first direction. The second actuator is disposed at an end of the substrate support and coupled to a second linear track disposed along the end of the substrate support and oriented in a second direction perpendicular to the first direction. The first and second actuators are positioned to engage with the substrate simultaneously. The controller moves the first and second actuators together to rotate the substrate.Type: ApplicationFiled: June 29, 2023Publication date: November 2, 2023Applicant: Kateeva, Inc.Inventors: Eashwer Chandra Vidhya Sagar Kollata, Digby Pun, Cormac McKinley Wicklow, Gregory Lewis
