HP Additive’s Arvind Rangarajan outlines MJF and industrial filament strategy for aerospace and defense

Arvind Rangarajan, Global Head of Product & Strategy at HP Additive Manufacturing Solutions, outlined Multi Jet Fusion (MJF) and industrial filament systems for aerospace and defense serial production. He framed MJF around validated materials, controlled processes, and consolidating multi-part assemblies into single-material components-not multi-material builds. Industrial filament printers with HP’s Material Management System (MMS) add high-temperature materials and full production traceability for qualification. With Würth Additive Group’s Digital Inventory Services (DIS), HP cites on-demand spares: Würth Canada cut a pandemic repair delay costing nearly CAD $300,000 a year-85% from missing body clips-from weeks to days.

This is strategy messaging, not a product launch, yet it places HP’s polymer stack where aerospace-defense buyers weigh qualification, repeatability, and inventory cost over machine demos. Polymer MJF suits systems-adjacent parts better than the metal LPBF grind; unmanned air and underwater platforms are a clearer near-term pull for durable polymer end-use parts. Score HP on process control, MMS traceability, and partners such as Würth-not multi-material claims it does not offer.
