The COVID-19 pandemic has caused unprecedented public health and economic crises around the world. The protection of human health and life has become the most important challenge. Disrupted supply chains resulted in shortages in the supply of essential medical equipment and personal protective equipment. The quick response to this situation was the use of 3D printers for the production of this type of article, especially for the medical service. The initial experience presented in this article (the review of solutions and initiatives based on cooperation in the field of 3D printing during the first wave of the pandemic) showed the challenges faced by organizations engaged in 3D printing during the pandemic. The performed identification and compilation of the difficulties that occurred during cooperation in crisis conditions allowed the author of this article to present an original proposal to minimize the most important of these problems. The main purpose of the article is to present the concept of a cooperation model based on an internet platform in the field of 3D printing during the COVID-19 pandemic, which will allow to increase the efficiency of management of activities necessary in crisis conditions.
