MSC Software公司发布了专为金属增材制造工艺开发的仿真软件“Simufact Additive”。在使用3D打印机制作金属模型时，该软件可考虑到造型过程中发生的热变形等的影响进行形状及支撑结构的设计。该软件除了可对造型中的热变形实施预测仿真以外，还具备与从打印床切断部件、去除支撑结构、热等静压（HIP）等工艺有关的功能。凭借这些功能，在生产阶段便无需反复尝试，可高效率实施造型，节省时间和成本。另外，MSC公司成今后还将为该软件配备热-结构耦合分析、温度履历管理、基于拓扑学优化的造型形状设计、支撑材料设计等功能模块。
Simufact Additive is a powerful and scalable process simulation environment for ‘right first time’ optimization of laser powder bed fusion processes. Features include simulation of all the key AM process steps starting with ‘printing’ of the part; followed by heat treatment, cutting the part off the build plate and removal of support structures, plus heat and pressure combined processes (HIP). The initial release of Simufact Additive will predict the final distortion and residual stresses of metal 3D printed parts; future functional enhancements will introduce additional features.
The modelling is carried out using CAD data in an innovative and newly developed Graphical User Interface (GUI) environment aligned with the real process work flow. Simufact Additive offers an intuitive approach which starts with defining the general process by determining the part and support components through to definition of manufacturing parameters up to the analysis settings and ultimate results. The software helps to compensate the distortion, minimize residual stresses and optimize the process parameters.
The concept behind the software is that it lays the foundation for a wide variability and scalability through different levels of details. This includes both a fast mechanical method for the prediction of distortion and residual stresses up to a fully thermo-mechanically coupled transient analysis which will be released soon. This will determine the temperature history and derived properties like the microstructure. The properties of the final part are available for a subsequent structural simulations.
