Problems solved by technology

[0003] In view of the above defects or improvement needs of the prior art, the present invention provides a brush-type 3D printing method and system assisted by augmented reality. The model is the preview path of the 3D printer model printing; then during the on-site printing process, the augmented reality information including the preview path is displayed to the on-site operators through the user's wearable device, so that the on-site operators can accurately operate the on-site hand controller, and then Map the movement of the on-site hand controller to the on-site 3D printer, so that it can extrude the printing material to print the 3D model on the irregular surface, thereby solving the problem that printing on the irregular surface is difficult and the effect is poor. technical problem

Abstract

The invention discloses a paintbrush type 3D printing method and system under the assistance of augmented reality, and belongs to the technical field of 3D printing. According to the method, firstly, a hand controller simulation platform is used for depicting a three-dimensional model to obtain a preview path after the three-dimensional model is completely printed; then, in the field printing process, augmented reality information including the preview path is displayed to a field operator through a user wearable device, so that the field operator accurately operates a field hand controller, and then the movement amount of the field hand controller is mapped to a field 3D printer; and a printing material is extruded to print the three-dimensional model on the irregular curved surface. According to the method provided by the invention, an operator realizes paintbrush type printing creation on the free-form surface under the assistance of augmented reality information according to the preview path in the virtual environment, and the method has a relatively good application prospect in printing of the free-form surface, ancient building repair and the like.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, and more particularly, relates to a brush-type 3D printing method and system assisted by augmented reality. Background technique [0002] 3D concrete printing technology does not require building formwork, which can break the limitations of traditional building design, and has the advantages of saving and environmental protection. Due to the fluidity of concrete itself, it is difficult to control the printing quality under the control of the traditional printer program, and the path planning in the printing of irregular surfaces and the restoration of ancient buildings is complicated, and the printing effect is poor. SUMMARY OF THE INVENTION [0003] In view of the above defects or improvement requirements of the prior art, the present invention provides a brush-type 3D printing method and system assisted by augmented reality, the purpose of which is to obtain a complete printed three-dimen...
