Embodiment

[0019] Such as figure 1 As shown, the present embodiment provides a 3D printer, including a support 1, a material storage assembly 2, a high-precision jet pump 3, a guide rail 4, a printing nozzle 5, a drive assembly 6, a workbench 7 and a controller 8, and the drive The component 6 drives the print head 5 to move above the workbench 7. One end of the high-precision jet pump 3 is connected to the storage assembly 2, and the other end is connected to the print head 5. The controller 8 is provided with a memory 81, a switching module 82 and a processing Module 83, the memory 81 is used to store data, and the processing module 83 generates the printing path of the 3D printer according to the printing model, and controls the high-precision jet pump 3 to squeeze the printing material in the material storage assembly 2 into the printing nozzle 5, and through the printing nozzle 5. Eject the printing material to the workbench 7, and the printing is completed.

Abstract

The invention relates to a 3D printer. The 3D printer comprises a bracket, a storage assembly, a high precision injection pump, a guide rail, a printing nozzle, a driving assembly, a worktable and a controller. The driving assembly drives the printing nozzle to move above the worktable; one end of the high precision injection pump is connected to the storage assembly while the other end of the high precision injection pump is connected to the printing nozzle; the controller is provided with a memory, a switching module and a processing module; and the processing module controls the 3D printerto be switched between a normal printing model and an edge printing model through the switching module. By switching the 3D printer between the normal printing model and the edge printing model, the printed model is more accurate and the printing error is reduced.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a 3D printer. Background technique [0002] Existing 3D printers usually divide the 3D printing model into multiple layers to form multi-layer planar images, and then print the planar images superimposed in sequence to form a three-dimensional model. [0003] The models printed by existing 3D printers have a certain height because each layer is printed, and when the printed model is completed, it will appear stepped. The greater the height of each layer, the more obvious the distortion, so that the accuracy of the printed model is not high. Contents of the invention [0004] The invention provides a 3D printer, which selects a corresponding printing mode according to judging whether the current printing point is located on the contour line, thereby reducing printing errors and making the printed model more accurate. [0005] In order to solve the above-mentioned technical ...
