This research aims to assess the current state of cost-benefit analysis and sustainability assessment in additive manufacturing.
Conducted a systematic literature review of AM cost-benefit and sustainability assessment methods from 2015 to 2025.
Analyzed evolution from direct cost models to those incorporating hidden costs, process characteristics, and life cycle considerations.
Identified gaps in capturing sustainability costs and proposed new frameworks for integration.
Found that early cost models focused mainly on direct costs but have evolved to address hidden and process-specific costs.
Highlighted persistent gaps in sustainability assessments, particularly in integrating environmental and social factors.
Proposed future research directions, including the integration of sustainability factors into models and empirical validation.
