Publication number: 20220152930Abstract: A spreading system for an additive manufacturing machine. The system has a roller rotatable about a rotary axis and having an exterior cylindrical surface to spread build material. A sensor senses material attached to the exterior cylindrical surface of the roller. A cleaning member abuts the exterior cylindrical surface of the roller and removes attached material therefrom. A controller rotates the roller whilst in abutment with the cleaning member in response to the sensor sensing material attached to the exterior cylindrical surface of the roller.Type: ApplicationFiled: August 5, 2019Publication date: May 19, 2022Applicant: Hewlett-Packard Development Company, L.P.Inventors: Guillermo Moliner Clemente, Eduard Galdeano Castillo, Alejandro Torres Pinero
