Purpose: The COVID-19 pandemic caused global supply disruptions and shortages that resulted in countries battling over desperately needed (medical) supplies. In this mayhem, additive manufacturing (AM) provided relief to the strained health care systems and manufacturing environments by offering an alternative way to rapidly produce desired products. This study sheds light on how additive manufacturing was used globally in response to the COVID-19 pandemic.

Methodology: The study undertakes a systematic and content-centric review of 289 additively manufactured products made in response to the COVID-19 pandemic. Additionally, quantitative frequency-based text mining and various descriptive analyses were applied that support the investigation of the subject under regard.

Findings: Results show that AM was primarily used in the medical domain for the production of standard medical items, such as personal protective equipment but also for non-obvious and new applications (e.g. swab simulator, rapid diagnostic kits). Also, certain paradigm shifts were observed, as the effective move to mass production and the mitigation of problems related to certification and standardization emerged as prominent management prospects. Nevertheless, various obstacles arose and remained in the path of lasting AM success, especially with respect to print quality, raw material supply, and technological versatility.

Originality: Due to the actuality of the topic under investigation, no comparable study has so far been conducted. The systematic review provides a conclusive and precise foundation for further analysis and subsequent discussions. Additionally, no comparable study mapping such a wide array of different AM products exists today.
