3D Printing Role in Filling the Critical Gap in the Medical Supply Chain during COVID-19 Pandemic

Supply chain operations are disrupted due to natural disasters or epidemics. In the recent period, the supply chain suffers from obstacles and major challenges that affect its stages directly due to the spread of the COVID-19 epidemic around the world. The impact of this epidemic on supply chain performance is clear in terms of supply, demand, or logistics. This epidemic is characterized by a rapid spread, so countries have taken preventive policies in an attempt to limit its spread. These policies are direct impacts on the performance of the supply chain in all scopes. The extent of its impact varies from one supply chain to another, according to the activities that the supply chain provides. In order to provide a more accurate study of the impact of the measures taken to limit the spread of the epidemic, this research presents a proposed framework that evaluates the impact of these policies on the three main aspects of the supply chain (supply, demand, and logistics). The proposed framework is build using BWM and TOPSIS based on plithogenic set. Plithogenic set provides a more accurate evaluation result that addresses the uncertainty problem. Supply chain aspects were evaluated for the food industry, electronics industry, pharmaceutical industry, and textile industry.

“…3D printing can produce any complex and any shape products in any field with cost independent of batch size in any place [3]. This unique advantage of 3D printing has been well reflected during this year's epidemic, and has become an important part of the supply chain of world epidemic prevention system [4].…”

3D printing technology, as one of the most subversive technologies in the 21st century, processes the entity through layer by layer superposition. It breaks through the design constraints and adapts to customized production with high flexibility, which is an important direction of industrial development in the future. 3C product has a very board application market and groups, so it has been widely valued over the world. The advantages of 3D printing technology are very suitable for the characteristics of 3C product, such as diversification, small-volume, personalized. Here, the impact of 3D printing technology on manufacturing industry is firstly discussed; 3C product manufacturing system integrated with 3D printing is finally put proposed. The advantages of the proposed system possess shorter manufacturing cycle, supply chain and logistics. It makes easier to realize personalized 3C product, localized manufacturing and reduce cost. The development and wide application of 3D printing technology in 3C product industry will make the manufacture of low-cost small batch or even individual customized products into a general mode towards the trend of "light luxury + light customization".

“…Another approach to provide products uses the technically and economically-viable open source small-scale digital technologies and off-the-shelf components for distributed manufacturing [21] , [22] . There has already been a concerted effort to apply open source hardware and 3-D printing during the COVID-19 pandemic [23] , [24] , [25] , [26] , [27] , [28] , [29] . In addition, challenges with supply chains during any type of pandemic can be partially offset by open source recyclebots [30] , [31] , [32] , [33] , [34] and direct recycling extrusion [35] to close the loop on material supplies with local waste converted into additive manufacturing feedstock [36] , [37] , [38] , [39] , [40] , [41] .…”
