In the modern world, carbon emission, waste management, and deterioration have become significant challenges in front of supply chain managers. Therefore, this study develops a vendor-buyer sustainable inventory model for deteriorating items in an inflationary environment with 3D printing techniques, volume agility and trade credit policy when customers' demand influenced by selling price and energy consumption factors. The emission from supply chain operations are controlled by investment in green technology with a carbon tax policy, while to mitigate the rate of deterioration, preservation investment is used. An algorithm is evolved to efficiently determine the optimal solution within this framework. Also, numerical and sensitivity analysis is performed to elaborate the importance of this model. The outcomes of the proposed model revealed that a supply chain manager could easily control the excess energy and number of defective items using a flexible production process that maximized the total profit. Furthermore, investing in 3D printing and green technologies helps improve environmental performance. [ABSTRACT FROM AUTHOR]
