在CATIA V5中设计的部件现在可以直接进入3D打印机

ByLeslie Langnau|2019年10月17日

在过去三年中,由九个合作伙伴组成的国际联合会成功地为航空业提供了更资源的效率效率。CENIT通过提供包含相关接口的升级的CATIA V5 CAD系统,播放了关键作用。该系统现在可以在单个软件程序中完全映射组件的3D打印过程 - 从设计到后处理。

由于基于由Fraunhofer研究机构为Addivation Technologies IAPT开发的单元电池为基础的3D打印零件的仿生支撑结构,软件用户可以节省材料,时间,从而在未来的成本 - 具有改善的质量结果。“仿生飞机”的研究发现作为添加剂生产领域的跨行业解决方案的基础。初始软件培训已经开始。

Bionic Aircraft 2D support structure

“从一开始,3D印刷和仿生设计在欧盟委员会资助的研究项目中发挥了重要作用。最终,我们有一个雄心勃勃的目标,这是为了减少飞机组件的重量,并在最终减少燃料消耗中,“Project Coordinator博士从Fraunhofer Iapt位于汉堡博士。

With the interface from the CAD system CATIA V5 has for the 3D printer, components can now be printed from the CAD software directly. “Decisive in connection with this is that all process steps, including post-processing, can be mapped in CATIA V5,” says Jochen Michael, Senior Consultant at CENIT and adds: “There is no need to exit the development environment and no data needs to be converted, which saves time and increases quality.”

The research work by Fraunhofer IAPT was inspired by nature. Whether butterfly wings or tree crown, each grid and branching structure inspired the project team to develop support structures for 3D parts using less material and at lower costs, with the added benefit that they are easier to remove. Support structures provide the needed underpinning to additive manufactured components at certain areas and must be removed after the 3D print either manually or by milling. In addition to the latest development, the Fraunhofer IAPT team has validated existing support structures and assigned them to certain application scenarios. As a result, they can be automatically selected during the 3D printing process in the future.

最终里程碑:单位细胞
In particular, the focus of the project partners over the past few months has been to iron out the fine details of the 3D printing process chain. With the resulting toolset, the support structures are now implicitly created. This means that in CATIA V5 a volume is created instead of the individual geometries. And the volume is attached to an attribute in the form of a color. The volume is only filled with the geometry of unit cells in one of the following steps. “The unit cells make it possible to freely develop the support geometry, without affecting the performance of the CAD system. What is possible now, for example, are graded support structures in various layers that can differ in their structure,” explains Jochen Michael the innovation.

单位单元可以被想象为生成几何形状的任何尺寸的立方体。可以定义任何数量的单个单位单元格。将这些单元电池分成层。颜色(属性)与配置文件中的相应单元单元链接。优点:单位单元仅创建一次,并且可以根据需要重新使用多次。切片数据以中性XML格式存储。然后,在最后一步中,应用Cenit开发的后处理器。它生成机器的特定数据。它生成激光在曝光过程中通过的路径,并填充具有预制单元单元的区域。“直到这一点,”实际的最终几何形状“不会产生,”Imgrund博士解释。

“仿生飞机”:航空业更多资源效率
Since September 2016 to August 2019, the objective of the “Bionic Aircraft” research project funded by the European Commission (grant number 690689) has been to increase resource efficiency in the aviation industry. Nine international consortium partners from industry, research and development, among them also the IT specialist CENIT and the Fraunhofer Research Institution for Additive Manufacturing Technologies IAPT, are collaborating to come up with new methods and concepts. The focus was on additive production and bionic design.
