Abstract
A hot bed deformation tolerance structure for a large-sized continuous fiber high-temperature 3D printer is provided. Size changes caused by thermal expansion of a hot bed are compensated through motion coordination of a secured hot bed support assembly and a motion device, especially for an aluminum alloy material. A Z-direction motion structure of this structure is fixedly mounted with a frame and works at room temperature. A compensation motion module is fixedly mounted with a Z axis and incompletely secured with the hot bed support assembly, and works at room temperature with the Z axis. The hot bed support assembly is incompletely secured and partially in a high-temperature chamber, with a maximum working temperature of 300° C. The hot bed support assembly retains motion redundancy in a direction of thermal expansion deformation, tolerates thermal deformation through a linear motion module, and compensates for metal deformation through horizontal motion coordination.
