Abstract

The invention discloses a reconstructible casting molding fast 3D printing method based on a reconstructible casting mold. The method comprises the steps: step 1, establishing a three-dimensional model of a part based on Solidwork and Pro / E three-dimensional modeling software; step 2, analyzing the three-dimensional model, to obtain a stl-format standard format model; step 3, analyzing the stl-format standard format model to obtain a g code of an enveloping ball motion track; step 4, with the g code as a driver, reconstructing the reconstructible casting mold, and making the reconstructed casting mold matched with the three-dimensional part model; step 5, based on the reconstructed reconstructible casing mold, pouring a heated liquid or semi-liquid 3D printing material into a casting mold cavity; and step 6, after pouring is completed, dismantling the casting mold, and thus obtaining a molded and preformed part model. With adopting of the method based on the casting and the reconstructible casting mold, molding and performing of the part is achieved, and the speed, the efficiency and the application range of 3D printing of the part are greatly improved.

Description

technical field [0001] The invention mainly relates to the fields of rapid prototyping and three-dimensional manufacturing of parts, and in particular to a rapid 3D printing method for reconfigurable casting. Background technique [0002] Additive manufacturing has a history of decades, and there are many research contents in traditional metal parts forming and manufacturing. With the development of computer technology, 3D printing technology of additive manufacturing has attracted more and more people's attention in recent years. Especially with the mature application of ABS, ULTEM, PPFS / PPSU, and Polyjet photopolymerization materials in light industries such as medical treatment, teaching, toys, and plastic parts molding, 3D printing has received national attention. [0003] Referring to Baidu Index and HowNet Index, we can find that 3D printing technology has grown exponentially since 2010, regardless of academic, media and user attention. For example, using 3D printing...
