Abstract: A method for generating a 3D printing file includes: layering a 3D model into a plurality of sliced layers, and obtaining contour data of each of the sliced layers; determining a straight line X=X0 corresponding to an abscissa X0 of an intersection point of a preset seamline on the current layer of the sliced layers; determining coordinates of a seam point in accordance with the straight line X=X0 and contour data of the current layer, adding the coordinates of the seam point into the contour data of the current layer to update the contour data of the current layer, and setting the seam point as a start printing point of the current layer; and generating the 3D printing file of the 3D model in accordance with updated contour data of each of the plurality of layers. A 3D printing device, a computer device, and a storage medium are also provided.

Abstract: A method and a device for determining a print position of a 3D model, a computer device, and a storage medium are provided. The method includes: obtaining an objective 3D model selected by a user and determining a projection of an objective area including the objective 3D model to a print plane; determining whether storage data exists; determining a first print position of the objective 3D model on the print plane in accordance with the projection when the storage data exists; and determining a second print position of the objective 3D model on the print plane in accordance with the projection and the storage data when the storage data does not exist. No intersection is existed between the second print position and the storage data.

Abstract: A model support point setting method includes: layering a model into a plurality of layers in accordance with a preset layer height, and obtaining a contour of each layer; locating a suspended layer in accordance with the contour of each layer; obtaining a suspension position of the suspended layer in accordance with a contour of a lower layer of the suspended layer and a contour of the suspended layer; determining a contour of an overhang position in accordance with the suspension position of the suspended layer, and determining a sharp corner area and a non-sharp corner area of the overhang position in accordance with the contour of the overhang position; and setting support points on the sharp corner area and the non-sharp corner area in accordance with corresponding preset support point densities. A model support point setting device, an electronic device, and a computer readable storage medium are also provided.

Abstract: A 3D printer extrusion structure, comprising: a housing; a motor provided on the housing; an active extrusion gear provided in the housing and connected to the motor; an adjusting support rotatably connected inside the housing; a driven extrusion gear provided at one end of the adjusting support and rotatably connected to the adjusting support; and an elastic member, the elastic member being connected to an other end of the adjusting support to enable the end of the adjusting support provided with the driven extrusion gear to approach the active extrusion gear, so that the driven extrusion gear works in conjunction with the active extrusion gear to extrude material, wherein the end of the adjusting support provided with the driven extrusion gear extends to the outside of the housing.

Abstract: Provided is a strain sensor including a fixing plate and a strain gauge. The fixing plate includes a first supporting part and a second supporting part flexibly connected to the first supporting part. The present application is advantageous in that a strain sensor with a simple structure, high reliability and high sensitivity is provided. The horizontal status of a contact surface may be detected by a little amount of deformation, and the flexible fixing plate can provide a buffer for the equipment to prevent damages due to direct impact.
