Problems solved by technology

[0003] The production method of traditional microcellular foamed products has to go through stages such as underwater extrusion granulation, supercritical infiltration of granules, preparation of foamed granules, and steam compression molding. The preparation process is relatively complicated and the cost is high. The special structure that cannot be realized is also difficult to realize only by molding

Abstract

The invention discloses a method and apparatus for producing a foamed product based on 3D printing. The apparatus mainly comprises a molding unit, a supercritical infiltration unit and a foaming unit, wherein the molding unit is a 3D printer and mainly comprises a three-dimensional ball screw sliding table, a molding platform, a 3D printer case, a plasticizing screw, a heating ring and a nozzle; the supercritical infiltration unit is mainly composed of a preheater, a booster pump, a CO2 storage tank and an infiltration vessel; and the foaming unit is mainly composed of a steam generator, a foaming case and a cover plate. The method comprises the following steps: printing a three-dimensional model via the molding unit according to product needs; then putting the three-dimensional model into the infiltration vessel in the supercritical infiltration unit and carrying out infiltration by using supercritical CO2; and carrying out steam foaming in the foaming case so as to obtain the foamed product. According to the method and apparatus provided by the invention, production stages are simplified to three production stages, so production cost and process complexity are reduced, and simplified production of foamed products with any complex structures can be realized.

Description

technical field [0001] The invention relates to a foaming process, in particular to a process for producing foamed products combined with 3D printing. Background technique [0002] Rapid prototyping technology (also known as rapid prototyping manufacturing technology, Rapid Prototyping Manufacturi-ng, referred to as RPM), also known as 3D printing. This technology manufactures entities in a layer-by-layer manner through molding equipment based on the three-dimensional model data of the object. This technology can overcome the special structural obstacles that cannot be realized by traditional mechanical processing at present. Simplified production of arbitrary complex structural components can be realized. The existing 3D printing technologies are mainly divided into fused deposition modeling (FDM), stereolithography (SLA), selective laser sintering (SLS), stereolithography (SLA), three-dimensional jet printing (3DP) and digital light processing. (DLP) and so on. [0003...
