AMSIG Tech Session – April 17,2024 Revolutionizing Manufacturing with HP Multi Jet Fusion: A Comprehensive Workflow Overview

By Hani Qaqish

In the realm of additive manufacturing, HP Multi Jet Fusion stands as a beacon of innovation, offering a revolutionary approach to production. Let’s dive into a comprehensive overview of this groundbreaking technology and its seamless integration within Siemens NX, empowering manufacturers to achieve unparalleled speed, precision, and efficiency.

Harald Moers, a seasoned expert with over two decades of experience at Siemens, leads us through the intricacies of the HP Multi Jet Fusion workflow. As part of Siemens’ additive manufacturing program, Moers sheds light on the technology’s evolution and its pivotal role in Siemens’ software portfolio.

At its core, HP Multi Jet Fusion employs a layer-by-layer process, depositing thin layers of preheated powder on a build platform. Droplets of fusing and detailing agents are precisely dispensed, harnessing infrared light to fuse the powder, resulting in intricate, high-quality parts at astonishing speeds.

One of the key highlights is the remarkable build speed, surpassing traditional methods like selective laser sintering (SLS) by over tenfold. This acceleration, coupled with superior part quality and sharp edges, positions HP Multi Jet Fusion as a game-changer in additive manufacturing.

The workflow within Siemens NX seamlessly integrates various stages, from part quality checks to print file creation. Each step is meticulously crafted to optimize efficiency and precision, ensuring a smooth transition from digital design to physical production.

Critical elements such as cut part quality checks and automatic nesting play pivotal roles in streamlining the process and enhancing final part quality. The ability to customize print parameters at both the part and build levels further underscores the versatility and adaptability of the workflow.

A standout feature is the automatic nesting capability, which optimizes part placement on the build tray, maximizing build density and minimizing material waste. Additionally, advanced functionalities like slice distribution analysis empower users to fine-tune print settings for optimal results.

The culmination of the workflow is the generation of a comprehensive print job file, containing all necessary information for seamless execution on HP Multi Jet Fusion printers. From serial numbers to material consumption data, every detail is meticulously documented, ensuring traceability and quality control throughout the production process.

As manufacturing continues to evolve, HP Multi Jet Fusion remains at the forefront of innovation, empowering industries to embrace the future of additive manufacturing with confidence and efficiency. With Siemens NX as a trusted ally, manufacturers can unlock new possibilities and redefine the boundaries of what’s possible in manufacturing.

In conclusion, the HP Multi Jet Fusion workflow, integrated seamlessly within Siemens NX, represents a paradigm shift in additive manufacturing, offering unparalleled speed, precision, and efficiency. As industries embrace this transformative technology, the future of manufacturing is brighter than ever before.
