Swedish software developerHexagonand aerospace firm雷神技术have developed a program that allows metal 3D printer users to predict and prevent part defects before they happen.
Developed using the firms’ joint software expertise, the program is said to allow designers to evaluate the outcome of an upcoming print, without having to go through painstaking trial and error. Designed to compliment六边形的剪裁加法platform, the software tool is said to be launching with a similar UI, so that users can access greater functionality but don’t have to relearn interfaces.
“我们已经与雷神技术公司合作，提供了一种直观且可访问的工具，该工具将帮助工程师快速预测和减轻风险，”六边形全球业务发展总监杰夫·罗伯逊（Jeff Robertson）说。“评估中尺度上的全激光粉床融合（LPBF）零件的能力将减少实现零件认证并从而支持工业化的努力。”
雷神的3D打印短途旅行
Based in Virginia, Raytheon is an aerospace and defense multinational. As such, the firm’s R&D efforts span multiple industries and technologies, but it has maintained a longstanding interest in 3D printing, particularly on the aerospace side of its business. In July 2020,美国制造named Raytheon as the winner of one of its Project Calls, along with its $841,000 funding prize.
The firm’s project submission, which included input from its Intelligence and Space, Missiles and Defense, and Research Center divisions, proposed the development of a revised LPBF software workflow. Using this, Raytheon said it’d be possible for adopters to easily create topologically optimized ‘exotic designs’ with conventional additive materials, like optimized3D printed optical mountsfor the美国空军。
发动机制造商和雷神公司Pratt & Whitney也是该技术的长期采用者。在International Paris Air Showin 2019,GKN航空航天揭示了它已将与公司的合作伙伴关系扩大到GTF发动机零件的3D打印，，，，including a Fabricated Fan Case Mount Ring and Fan Spacer.
Complimenting Simufact Additive
Hexagon的现有建模加成式程序旨在使Metal 3D打印机用户能够通过在打印之前模拟构建来削减测试时间。该平台与LPBF，直接能量沉积（DED）和粘合剂喷射技术兼容，采用多尺度方法来解决问题，从机械检查到完整的热机械瞬态分析。
The platform itself is based around numerical simulation specialistMSC软件MARC solver, a technology that covers a wide range of physical effects that’s been adapted for 3D printing. In Simufact Additive, the software tool allows users to minimize residual stresses, compensate for distortions, identify potential part failures, assess post-processing impact, optimize build plate nesting and more.
从本质上讲，该程序通过使采用者能够在将结果与构建目标的几何形状进行比较之前，以使缺陷清晰，然后通过分析突出显示修复的方式来模拟打印。根据Hexagon的说法，制造添加剂最终减少了制造商的学习过程，同时确保他们优化员工生产率并最大程度地减少其产品的市场时间。
在其最新的软件创新、六角Manufacturing Intelligence division has worked with Raytheon Technologies’ Pratt and Whitney business, to develop a brand new simulation tool. As well as being complementary to Simufact Additive, it has been revealed that the technology will enable designers to evaluate print outcomes based on a combination of materials, geometries and print processes.
It’s also said the similarity of the software’s UI will allow for its easy integration into existing manufacturing processes without the need for extensive training, something David Furrer, Pratt & Whitney’s senior fellow for materials and processes, adds will “help manufacturers with all levels of experience make better products with greater efficiency.”
Though there’s no doubt Simufact Additive has proven popular, as its clientbase includes the likes ofAudi，，，，Mercedesand捷豹，它远非该领域唯一的软件。ANSYS Additive Print例如，允许用户评估材料在构建过程中的压力或扭曲方式，并采取纠正步骤以首次正确获取零件。
Similarly,Riven’s Warp Adapted Model softwareallows users to capture and use full-part 3D data from an initial design to identify and correct errors in minutes. Designed to work withAuthentiseAMES, the FFF, SLA, MJF and binder jetting-compatible technology unlocks full contextual data capturing, as a means of picking out divergences from part models.
