剪裁launches metal binder jetting simulation tool for Simufact Additive

仿真软件开发人员剪裁has announced the launch of a simulation tool for the metal binder jetting 3D printing process for its剪裁Additiveprogram.

该软件的用户将能够预测和预防 - 在设计阶段 - 经常用于后处理的烧结效果可能会在粘合剂喷射零件上具有。新功能最终旨在使制造商能够在其现有机器上实现工业级零件质量。

Simufact产品管理高级总监Gabriel McBain博士指出:“我们很高兴向市场引入第一个模拟金属粘合剂喷射烧结过程的解决方案,以便制造商可以利用这一重要的新方法。我们知道客户将金属粘合剂喷射视为制造业的关键技术,尤其是在需要在汽车行业等大量销量下生产复杂的零件的情况下。”

How does metal binder jetting work?

金属粘合剂喷射是最快,最可持续的添加剂工艺之一。它通过将精确的液体结合剂喷涂到金属粉末上来起作用,这又将粉末结合到固体层中。这些层一次彼此印刷,一次将其产生所需的3D模型。

粘合剂喷射系统往往具有较大的构建量,并且不需要支撑结构,因此与粉末床融合相比,它们通常具有更高的生产量功能。出于这个原因,Simufact认为,该技术可以完全替换低体积,高成本的金属注塑成型,以用于汽车,医疗甚至航空航天中的各种应用。

但是,从建筑室中刚出来的零件通常需要大量的后处理,因为它们处于“绿色状态”,这意味着它们特别脆弱。烧结可以用作增加这些部分密度并改善其机械性能的后处理步骤。问题:烧结可能会导致一部分收缩多达35% - 需要在设计阶段将这种失真置于缩放尺寸的情况下。

旨在替代传统但昂贵的反复试验方法,Siputive添加剂的新粘合剂喷射工具旨在在计算上预测收缩的收缩。然后,制造商将能够根据需要补偿和扩展其尺寸,而无需在热模拟方面的任何专业知识。

此外,该工具还可以预测零件中烧结引起的机械应力,从而指出可能发生缺陷的地方。借助手头的知识,工程师应该能够在产品生命周期的早期进行设计更改,从而导致失败的尝试较少。

作为顶部的樱桃,型号设置和仿真阶段是完全自动化的,可以进一步定制Pythonscripts. As a final validation stage for the compensation, the optimized geometries can be immediately compared to both the initial STLs and a metrology scan of a manufactured part within the UI of the program.

预测性和仿真工具在降低成本和缩短新颖零件上市的时间非常有用。工程公司etteplanrecently developed a new, free online tool to计算3D打印的生产成本– AMOTool. The software program enables companies to computationally calculate the costs associated with manufacturing an object using a well-established metal 3D printing method, before any production has even taken place.

Taking a deep learning approach, geometric ML specialist物理recently launched what it is calling theworld’s most powerful geometric search engine– Thangs. Instead of scanning for text or images, Thangs uses deep learning algorithms to index 3D models based on the polygons, or triangles, that make up their volumes. The engine also provides version control functionality and ‘compatible part predictions’ for the 3D community.
