A magnetic assisted forming 3D printing forming device and method

Abstract

The invention discloses a 3D printing and forming device and method capable of realizing magnetic-assisted forming. The electromagnetic technology is combined with the 3D printing technology to realize the unsupported printing of a cantilever structure of a polymer-based magnetic metal composite product and the action of preventing the product from being warped. A control system accurately controls the working state of an electromagnet in a magnetism constructing platform according to real-time monitoring and calculation of a printing position and an extrusion capacity, the vertical upward magnetic force applied to the printed cantilever structure is balanced with the vertical downward gravity, and the printed molten cantilever can be stably suspended, cooled, solidified and formed in theair. The device and the method disclosed by the invention can effectively avoid establishment of a support part for the cantilever structure of the product during the 3D printing process, improve thequality of the original surface of the product in contact with a support surface, shorten the printing time and reduce the amount of consumables used in the printing process, so that the product has better quality; and a plurality of printing and extruding mechanical arms work simultaneously, and the technology capable of realizing completely-suspended printing and forming from different dimensions can be selected, so that the manufacturing efficiency of the product can be improved.

Description

technical field [0001] The invention relates to the field of 3D printing, in particular to a magnetic-assisted forming 3D printing forming technology. Background technique [0002] As a kind of 3D printing technology, fused deposition modeling technology is widely used in medical, fashion, industry, aerospace and other aspects. Fused deposition technology belongs to the bottom-up layered molding technology. In order to avoid the collapse of the cantilever structure due to gravity, the support structure must be pre-printed under the product, and the support structure needs to be removed after printing. This will print the model body Traces are left on the surface, which makes the surface quality of 3D printed products poor and plastic consumables are discarded, which is not conducive to environmental protection. The present invention proposes a scheme of fused deposition 3D printing that overcomes the gravity of an object and avoids printing a support structure—magnetic-assi...
