The project will produce a design framework for additively manufactured (3D printed) metal structures. The project will develop open source algorithms for predicting (i) mechanical properties of 3D printed metals for given printing parameters and (ii) internal stresses and distortions arising from the printing process. Underpinned by experiments on structural components and structural reliability analyses, models will be calibrated for the nonlinear analysis of 3D printed structures, and a methodology will be set out for designing 3D printed metal structures with acceptably low probability of failure. The project will enable structural engineers to safely and efficiently design 3D printed metal structures and components.

该项目将为增材制造（3D 打印）金属结构提供一个设计框架。该项目将开发开源算法，用于预测 (i) 给定打印参数下 3D 打印金属的机械性能，以及 (ii) 打印过程中产生的内应力和变形。在结构部件实验和结构可靠性分析的基础上，将针对 3D 打印结构的非线性分析校准模型，并将制定一种方法来设计故障概率较低的 3D 打印金属结构。该项目将使结构工程师能够安全高效地设计 3D 打印金属结构和部件。
