NP Aerospace deploys Caracol WAAM system to produce vehicle suspension parts in 60 hours, replacing castings

NP Aerospace has adopted Caracol's Vipra AM large-format wire arc additive manufacturing (WAAM) platform to produce Mastiff military vehicle suspension and differential brackets. The parts, previously manufactured as traditional castings, are now printed in 60 hours of machine time. The application targets defense vehicle sustainment, where legacy cast tooling is often unavailable or cost-prohibitive to reproduce for small-batch or obsolescence-driven production runs.

This deployment fits the defense vertical's accelerating adoption of AM for non-flight-critical ground vehicle components, where qualification pathways are shorter than aerospace but still demand ballistic and fatigue validation. WAAM's advantage over casting lies in eliminating pattern tooling lead times and enabling on-demand production without minimum order quantities. Caracol's Vipra platform competes with MX3D, WAAM3D, and Lincoln Electric's additive solutions, but the NP Aerospace case is notable for combining a defense prime's production-floor acceptance with a 60-hour cycle time that approaches casting economics at low volumes. The value-chain position is service-led: NP Aerospace is the end-user and integrator, not a machine reseller, which signals that WAAM is moving from technology demonstration into sustainment logistics.

For defense logistics managers evaluating WAAM, the practical takeaway is that 60-hour cycle times for suspension brackets are real but do not automatically generalize to all cast-part replacements. The economic case depends on part geometry, material utilization, and whether post-processing (machining, heat treatment, inspection) fits within existing maintenance workflows. NP Aerospace must now demonstrate repeatability across a fleet of vehicles, not just a single bracket set, before this becomes a template for broader defense sustainment programs.
