摘要

为了探究熔融沉积3D打印制品制备过程中，材料属性、填充密度、支撑结构等参数对制品力学性能和强度特性的影响，提出了一种基于强度需求的3D打印构型优化设计方法。通过有限元结构强度仿真计算，特征样品拉力实验对比分析，获得工艺参数相关的制品力学性能。研究结果表明不同内部结构3D打印制品相同填充密度(质量比)时，抗拉强度存在较大差异，其中，在理论分析和实验测试中，同心结构的抗拉强度较高，折线型和螺旋形抗拉强度较低。该研究成果对深入分析3D打印制件强度和填充结构的关系具有指导意义，为基于强度需求的3D打印参数优化设计提供了数据支持。

Abstract

In order to explore the effects of material properties, filling density, support structure and other parameters on mechanical properties and strength characteristics of 3 D printed products, an optimization design method of 3 D printed configuration based on strength requirements was proposed. The mechanical properties of the products were obtained through the simulation calculation of the finite element structure strength and the comparative analysis of the tensile test of the characteristic samples. The tensile strength of 3 D printed products with different internal structures has great differences when the packing density is the same. In theoretical analysis and experimental test, the tensile strength of concentric structures is higher, while that of folded lines and spirals is lower. The results have guiding significance for in-depth analysis of the relationship between the strength of 3 D printing parts and the filling structure, and provide research data support for the optimization design of 3 D printing parameters based on strength demand.
