A holistic decision framework for 3D printing investments in global supply chains

Three-dimensional printing (3DP), also known as additive manufacturing, is associated with potentially strong stimuli for revenues and cost savings. Nevertheless, the benefits of 3DP compared to conventional manufacturing methods or external sourcing require a holistic analysis for investment decision making. Until now, research has merely assessed case study-related potentials and specific aspects like production costs. Comprehensive information about value drivers in the overall supply chain is weak. Existing value-based supply chain management concepts are only of limited suitability. This paper develops a framework for investment decisions based on Economic Value Added (EVA), providing assessment of value drivers in global supply chains, including an empirical study with eight companies across different industries.
