Abstract

Lattice structure is a network of truss including struts or plates interconnected to each other. The lattice structures have many inherent advantages due to their ability to reduce the weight of the product whilst still ensure high specific strength and stiffness of materials. They have been used in many industrial engineering applications such as improvement of material properties, thermal engineering, and biomedical application. However, the generation of lattice structure model in Computer Aided Design (CAD) environment has many difficulties using the current commercial CAD software. Therefore, this paper presents an application of CAD to create a model of lattice structure for additive manufacturing technologies. An interface to generate a model of lattice structure has been developed in Visual Basic programming language based on the API functions in SolidWorks® software. The interface helps product designers generating automatically a complex model of lattice structure of designed product in CAD environment.

CAD环境下增材制造点阵结构的创建

点阵结构是一种桁架网络，包括相互连接的支柱或板。晶格结构具有许多固有的优点，因为它们能够减轻产品的重量，同时仍然确保材料的高比强度和刚度。它们已被用于许多工业工程应用，如材料性能的改善、热工程和生物医学应用。然而，在计算机辅助设计(CAD)环境下，使用现有的商用CAD软件生成网格结构模型存在许多困难。因此，本文提出了一种应用CAD创建增材制造技术晶格结构模型的方法。基于SolidWorks®软件的API函数，用Visual Basic编程语言开发了网格结构模型生成接口。该接口可帮助产品设计者在CAD环境中自动生成所设计产品的复杂网格结构模型。
