基于激光散斑法的模型变形测量研究

摘要

本文采用激光散斑法测量模型在不同承载状态下的变形数据，并与理论数据进行比较分析，为研究3D打印技术中成品的力学性能提供了实验参考。%It is one of the effective indicators for the performance of 3D printing technology whether or not its products can fully retain inherent mechanics parameters of the materials.A method to measure the deformation of 3D printing models in different load conditions by laser speckle is presented in this paper in comparison with some theoretical data,thus to offer an experimental reference for researches on mechanical property of materials in 3D technology.
