A three-dimensional forming device and method

Abstract

The invention discloses a three-dimensional forming device which comprises a forming cavity, a valve layer, a liquid storage cavity, a drive recycling device and a control device. The invention further discloses a three-dimensional forming method applied to the three-dimensional forming device. The three-dimensional forming method comprises the steps that three-dimensional envelope curved surface data of a three-dimensional model are determined according to a three-dimensional model to be produced; the height of a liquid column, needing to be injected, of each jet flow hole in the valve layer is calculated according to the three-dimensional envelope curved surface data; power needed by the drive recycling device and loads needed by valves in the valve layer are calculated according to the height of the liquid columns; the drive recycling device is controlled to continuously provide the power, the loads are exerted on the valves respectively, and a three-dimensional finished product is obtained. According to the three-dimensional forming device and method, the advantage that the viscosity of intelligent material fluid media can be fast changed along with external conditions is utilized, and the advantages that the forming speed is high and the generated model can be changed in real time are achieved.

Description

technical field [0001] The invention relates to the technical field of three-dimensional shaping, in particular to a three-dimensional shaping device and method. Background technique [0002] Three-dimensional molding has been widely used in various fields. The existing three-dimensional molding is mainly realized in the following ways: [0003] 1. Realize three-dimensional molding through traditional mechanical processing. [0004] For example, using a material with strong plasticity as the medium, the required three-dimensional model is generated by stamping through a three-dimensional mold, and another example is to form a thin shell by stamping metal or a material with strong plasticity. [0005] 2. For different media, realize three-dimensional molding through controllable curing process (including sintering process). [0006] For example, using UV-curable glue as the medium, the layered UV exposure process is used to layer the vertical section of the 3D model on one ...

Problems solved by technology

[0008] It can be seen that none of the 3D molding methods in the prior art can realize the direct reuse of the molding medium, let alone the real-time change of the 3D stereoscopic model that has been formed.
