A 5-axis 3D printing device and method for curved surface layered fused deposition modeling

Abstract

The invention discloses a hook face layering fusion deposition forming 5-axis 3D printing device and method. The device comprises a movable platform, a 3D printing head and a wire extruder. A plasticwire is conveyed into the 3D printing head through the wire extruder, the movable platform is arranged below the 3D printing head and connected with a supporting rod through a platform stretching-outshaft and a universal joint, and the supporting rod and a lifting device are connected. The edge of the movable platform is connected with the upper ends of three push rods through ball bearings. Thelower ends of the push rods are connected with sliding blocks through belt clamping pieces and spherical surface pair sphere centers. The sliding blocks are matched with vertical guide rails fixed toa fixed rack, the sliding blocks linearly move up and down along the guide rails, and the sliding blocks are controlled by motors via belts. According to the characters of a component three-dimensional model, three-dimensional model hook face layer cutting is conducted, and path planning data of each layer cutting hook face are obtained; kinematics parameters of the movable platform, the 3D printing head and the motors are obtained through mathematical derivation, and control is conducted through computer programs for component machining; and the hook face layering fusion deposition forming 5-axis 3D printing device and method have the beneficial effects of being high in precision and wide in printing range.

Description

technical field [0001] The invention belongs to the technical field of three-dimensional additive manufacturing, and in particular relates to a 5-axis 3D printing device and method for curved surface layered fusion deposition molding. Background technique [0002] 3D printing technology uses the principle of discrete superposition to realize rapid processing of products. Fused deposition modeling technology has become one of the most widely used technologies in rapid prototyping because of its advantages of convenient installation, simple use and maintenance, low cost, no pollution and no pollution. At present, the surface finish and mechanical properties of planar layer fused deposition molding products are poor, so that the application of the product is limited to model making or design verification, and it is difficult to use in more professional engineering applications. Various FDM rapid prototype machine structures developed in recent years mainly include: XYZ type, pa...
