Deposition and milling integrated double-station 3D printer

Abstract

The invention discloses a deposition and milling integrated double-station 3D printer. According to the deposition and milling integrated double-station 3D printer, firstly, a three-dimensional formed object to be printed is subjected to model treatment; in the treatment process, the forming process of the three-dimensional formed object is divided into two parts which are related in shape and different in function to conduct forming according to different principles; and according to the operation of dividing forming of the three-dimensional formed object into two parts which are related in shape and different in function to conduct forming according to different principles, a three-dimensional model is divided into an inner solid model, an inner contour model and an outer contour model, the inner solid model is subjected to additive forming through a fused deposition nozzle, the inner contour model and the outer contour model are subjected to subtractive forming through a milling module, and the fused deposition nozzle and the milling module are mounted on a multi-station lifting type switching tackle.

Description

technical field [0001] The invention relates to a 3D printing technology, in particular to a deposition-milling integrated double-station 3D printer. Background technique [0002] There are many defects and problems in the 3D printing technology of metal materials that use arc or plasma as the heat source for heating and melting, including: [0003] 1. Due to the uneven energy distribution, energy inconcentration, and unstable energy supply of the arc or plasma, various complex defects include: [0004] 1. Insufficient interlayer fusion caused by uneven energy distribution, non-concentrated energy, unstable energy supply, and uncertain factors in the energy conversion process; [0005] 2. Uneven energy distribution (point discharge), resulting in pores in the formed tissue; [0006] 3. Factors such as uneven energy distribution and metal heat conduction lead to internal stress in the structure, which eventually leads to interlaminar cracks in the formed structure; [0007...
