Abstract	Additive manufacturing has progressed from a rapid-prototyping technology toward an industrial production approach capable of reshaping how material, geometry, supply chains, and product life cycles are considered during product development. Its layer-by-layer fabrication principle permits near-net-shape production, topology-optimized structures, lattice architectures, functionally integrated components, part consolidation, localized production, and selected use of recycled or recovered feedstock. These capabilities create significant opportunities for reducing raw-material demand and manufacturing waste. Nevertheless, additive manufacturing should not be considered inherently resource efficient. Powder production, feedstock conditioning, support structures, failed builds, thermal processing, machine utilization, inert gases, post-processing, heat treatment, surface finishing, and electricity consumption can impose substantial resource and environmental burdens. This study examines the strategies through which additive manufacturing can contribute to genuinely resource-efficient product development. A structured integrative review was undertaken with emphasis on Design for Additive Manufacturing, topology optimization, lightweighting, part consolidation, support minimization, process selection, life-cycle assessment, life-cycle costing, circular manufacturing, recycled materials, repair, and distributed production. Current evidence indicates that the strongest sustainability outcomes arise when additive manufacturing is introduced at the design stage rather than used merely as a substitute for conventional manufacturing of an unchanged geometry. The study proposes a Resource-Efficient Additive Product Development Framework comprising functional requirement definition, manufacturing-route screening, material-efficient design, build-oriented optimization, life-cycle verification, circularity planning, and post-production learning. Published aerospace and space-manufacturing evidence illustrates the potential scale of material efficiency: recent review evidence reports conventional buy-to-fly ratios of approximately 20:1–40:1 with material waste reaching 95% in selected applications, compared with approximately 1:1–3:1 and about 5% reported waste for additive routes. These values are sector-specific and should not be generalized to all AM processes. The paper concludes that additive manufacturing becomes a resource-efficiency strategy only when design freedom, process efficiency, material recovery, product-use benefits, and end-of-life considerations are managed as one integrated product-development system.
