Impact of hybrid manufacturing on supply chain for metal parts

Hybrid manufacturing integrates the discrete advantages of (1) (near-net) additive manufacturing of complex parts made of super alloys without the need for fixtures and tooling along with (2) superior part accuracy and surface finish through traditional subtractive processes such as machining. The successful integration of hybrid manufacturing with the traditional supply chain for metal parts can significantly enhance current processing capabilities leading to additional product mix, complex customization, higher capacity utilization, and rapid response to low volume custom production demands. Hence, it is critical to understand the evolving hybrid manufacturing supply chain and its potential economic impact. This research analyzes the impact of hybrid manufacturing using data from original equipment manufacturers (OEMs) in order to identify the production issues that influence key operational, engineering, and business decisions. Using this data, an economic model is developed to investigate conditions under which integrating hybrid manufacturing will enable firms to gain additional benefits through existing supply chain. Major challenges, barriers, and relevant factors that could hinder the advancement of this evolving hybrid ecosystem are also identified. Findings from this study will provide traditional manufacturing firms with decision making criteria to evaluate post-processing of metal additive parts into their offerings.
