|1. (WO2018157474) SUPPORT STRUCTURE, PRINTING METHOD FOR SUPPORT STRUCTURE, AND PRINTING SYSTEM|
|Applicants:||ZHUHAI SEINE TECHNOLOGY CO., LTD.
|Title:||SUPPORT STRUCTURE, PRINTING METHOD FOR SUPPORT STRUCTURE, AND PRINTING SYSTEM|
A support structure and a printing method therefor, and a printing system. The printing structure comprises a material part printed using a first material and an immaterial part (11) printed using a second material, the material part comprising a grid structure (10), and the immaterial part (11) being filled inside each grid unit and outside each grid unit of the grid structure (10). The hardness of the first material is greater than the hardness of the second material. The grid density of the grid structure (10) varies within the printing plane, and/or the area of the cross section of the connection side of the grid unit varies along the direction perpendicular to the printing plane. The strengths of different parts of the support structure are different, such that the adverse effect of the support structure cracking, which is caused by the stress concentration when the support structure is subjected to stress during or after curing, can be effectively prevented.
