3D printing device for printing spherical surface and printing method
The invention discloses a 3D printing device for printing a spherical surface. The 3D printing device comprises a printing head, a mechanical arm and a rotating base; the mechanical arm is arranged onthe rotating base; the printing head is arranged at the end part of the mechanical arm; and the printing head can rotate around the rotating base. The 3D printing device further comprises a scraper arranged on the printing head, the scraper is located on the downstream side of the moving direction of the printing head, at least one part of the scraper is lower than the position of the printing head, the lower edge of the scraper forms a spherical shape when rotating around the rotating base, the radius of rotating of the lowest point of the scraper around the rotating base is equal to the maximum rotating radius of a discharge port of the printing head, and the moving path of the scraper and the printing path of the discharge port are at least partially overlapped. The invention also relates to a printing method. According to the 3D printing device and the printing method, block printing of a dome structure with the same spherical radius and different section body radii can be finished by only one printing head without using a template, thereby expanding the application of 3D printing to a spherical structure.
本发明公开了一种用于打印球面的3D打印装置，包括打印头、机械臂和旋转底座，机械臂设置在旋转底座上，打印头设置在机械臂的端部，打印头能够绕旋转底座旋转；3D打印装置还包括有设置于打印头的刮板，刮板位于打印头移动方向的下游侧，且刮板的至少一部分低于打印头的位置，刮板的下边缘绕旋转底座旋转时形成球面状，刮板的最低点绕旋转底座的旋转半径等于打印头的出料口的最大旋转半径，刮板的移动路径与出料口的打印路径至少部分的重叠。本发明还设计一种打印方法。本发明仅需一个打印头就可以完成具有相同球面半径不同截面体半径的穹顶结构的分块打印，无需使用模板，拓展了3D打印在球面结构的应用。
