Publication number: 20210187837Abstract: The present invention relates to a 3DP dislocated printing method and system. During layer-by-layer powder laying printing, printing heads are circularly closed and opened along a plurality of spray holes in two sides of the width direction, so that the spray positions of printing areas on adjacent layers corresponding to a same spray hole are mutually staggered. When individual spray holes of the printing heads are blocked, the corresponding positions of the blocked spray holes in the adjacent layers are also mutually staggered, and the problem of interruption of sections of a printing module caused by the phenomenon of missing spray of binders due to the blockage of individual spray holes on a single layer does not occur, thereby improving the 3DP printing efficiency, and reducing maintenance costs of the printing heads. The present invention also relates to a 3DP comprehensive printing method.Type: ApplicationFiled: October 30, 2018Publication date: June 24, 2021Applicant: KOCEL INTELLIGENT MACHINERY LIMITEDInventors: Fan PENG, Bao YANG, Zixiang ZHOU, Yinxue DU, Junwei WANG, Yi LIU
