Additive manufacturing is the more and more considered in industry, however efficient simulation tools able to perform accurate predictions are still quite limited. The main difficulties for an efficient simulation are related to the multiple scales, the multiple and complex physics involved, as well as the strong dependency on the process trajectory. This paper aims at proposing a simplified parametric modeling and its subsequent parametric solution for evaluating parametrically the manufactured part distortion. The involved parameter are the ones parametrizing the process trajectories, the thermal shrinkage intensity and anisotropy (the former depending on several material and process parameters and the last directly depending on the process trajectory) and the deposited layers. The resulting simulation tool allows evaluating in real-time the impact of the parameters just referred on the part distortion, and proceed to the required geometrical compensation.

增材制造过程中零件变形的参数评估

增材制造在工业中越来越多地被考虑，但是能够执行准确预测的有效仿真工具仍然非常有限。有效仿真的主要困难与多个尺度，所涉及的多个复杂物理以及对过程轨迹的强烈依赖有关。本文旨在提出一种简化的参数化建模及其随后的参数化解决方案，以参数化方式评估制造零件的变形。涉及的参数是参数化工艺轨迹，热收缩强度和各向异性的参数（前者取决于几种材料和工艺参数，最后一个参数直接取决于工艺轨迹）和沉积层。
