End-Use Parts: Evaluating FDM Additive Manufacturing
Review how manufacturers evaluate FDM 3D printing for selected end-use parts by assessing material route, application risk, qualification effort, inspection needs, and production workflow.
Key Takeaways
- FDM is positioned for low-volume and customized end-use parts, including quantities from one to around 1,000 where geometry is moderately to highly complex.
- The paper explains how FDM can support pilot production, bridge production while tooling ramps, and provide replacement or spare parts after a product is retired.
- The paper frames FDM as a complement to traditional manufacturing when complexity, customization, low volume, or lead time make conventional tooling less attractive.

Executive Summary
This whitepaper explains where FDM additive manufacturing can fit into end-use part production, from early pilot runs to bridge production, replacement parts, and spare parts. It focuses on practical manufacturing scenarios where low volume, customisation, or complex geometry can make conventional tooling inefficient.
The guide introduces the terminology behind additive manufacturing, end-use parts, and FDM, then outlines how production teams can use design freedom to consolidate components, reduce physical inventory, and optimize parts for function rather than for a fixed manufacturing process.
Readers will find examples from Nova Tech Engineering and Aurora Flight Sciences showing how FDM has been applied to customized production parts, lightweight UAV components, and hybrid smart parts. The paper is most useful for teams evaluating when additive manufacturing should complement molding, machining, or other established production methods.
