Abstract

The invention discloses a disk rotating multi-channel electron beam rapid prototyping method. The method comprises: 1. placing a three-dimensional part model on a forming area for slicing; 2. establishing a polar coordinate system to determine the position information of the three-dimensional part model ;3. Calculating the scanning trajectory points of the three-dimensional part model; 4. Spreading powder and positioning the forming area; 5. Scanning and melting the powder to obtain a single-layer solid sheet; 6. Resetting the forming area; ~The process in step six enables the single-layer solid sheets on the shaped base to be stacked layer by layer to obtain a three-dimensional part. The present invention accurately determines the position information of two or more three-dimensional part models on the disk worktable by establishing a polar coordinate system on the disk workbench of the disk rotating multi-channel electron beam rapid prototyping equipment, and then performs scanning and melting respectively, At the same time, the rapid prototyping of three-dimensional parts of different materials is realized, and the forming precision of the parts is improved.

Description

technical field [0001] The invention belongs to the technical field of additive manufacturing, and in particular relates to a disk rotating multi-channel electron beam rapid prototyping method. Background technique [0002] Electron beam selective melting technology (Electron Beam Selective Melting, EBSM) and selective laser sintering technology (Selective Laser Sintering, SLS) are two kinds of additive manufacturing technologies widely used at present. Hardware control technology can directly convert 3D CAD models into entities. Theoretically, any heat-bonded powder can be used as a raw material for additive manufacturing, such as polymers, ceramics, metal powders, and various composite powder materials. Electron beam selective melting rapid prototyping technology is that the electron beam scans line by line according to the pre-planned path driven by the deflection yoke, melts the laid metal powder, accumulates layer by layer, and manufactures the required metal parts. Th...
