Abstract

In the context of the COVID-19 pandemic and the lack of protective equipment worldwide, we aimed to study the literature for finding guidelines in the 3D manufacture of respiratory masks. We have searched for papers in CI-EXPANDED, SSCI, A&HCI, CPCI-S, CPCI-SSH, BKCI-S, BKCI-SSH, ESCI, CCR-EXPANDED, IC, using 3D printing materials sterilization and 3D printing materials disinfection keywords. From 80 results in databases, after refining, we selected six papers. We have also searched for manufacturers information regarding 3D printing materials sterilization or disinfection. We have found seven materials that are suitable for 3D printing and sterilization, with regards to multiple utilizations. Analyzing the properties and recommendations for sterilization of elements obtained by 3D printing, a thorough filaments structures/behavior research for most of the 3D models for printing is needed regarding synthetic polymers suitable for 3D printing; also, to establish the physical and chemical properties resulted after the reactions with sterilizing substances. In the context of the COVID-19 pandemic, the authors want to help and find guidelines in the 3D manufacture for producing respiratory masks.

Highlights

Since January 21, 2020, the World Health Organization [WHO] started to make reports on the Novel Coronavirus [2019-nCoV], stating that at the end of the year 2019, WHO China Country Office reported the first cases of unknown etiology pneumonia [1].WHO decided to declared COVID-19 infection pandemic on March 11, 2020, and described as" spreading from China worldwide and being confirmed 118,319 [80 955 in China] infections at that date" [2].On March 23, 2020, the confirmed cases with "COVID infection reached 362,051 cases, with 15,496 deaths and 100,657 recovered patients" [3].The spread of the pandemic has been rapid in Europe, especially in Italy, France, Spain, and worldwide
One of the significant problems in this pandemic is the rapid spread of the SARS-Cov2 virus, which requires the use of multiple protective materials: gloves, surgical or respiratory masks, goggles, face shields, gowns, disposable protective materials for covering the head, neck, and lower limbs, including the feet [4]
Since the development of 3D printing, over the past decades, the domain of application has evolved significantly [35]! From the experience of making parts required during this period, both advantages and disadvantages of using 3D printers were identified

Introduction

Since January 21, 2020, the World Health Organization [WHO] started to make reports on the Novel Coronavirus [2019-nCoV], stating that at the end of the year 2019, WHO China Country Office reported the first cases of unknown etiology pneumonia [1].WHO decided to declared COVID-19 infection pandemic on March 11, 2020, and described as" spreading from China worldwide and being confirmed 118,319 [80 955 in China] infections at that date" [2].On March 23, 2020, the confirmed cases with "COVID infection reached 362,051 cases, with 15,496 deaths and 100,657 recovered patients" [3].The spread of the pandemic has been rapid in Europe, especially in Italy, France, Spain, and worldwide. WHO decided to declared COVID-19 infection pandemic on March 11, 2020, and described as" spreading from China worldwide and being confirmed 118,319 [80 955 in China] infections at that date" [2]. On March 23, 2020, the confirmed cases with "COVID infection reached 362,051 cases, with 15,496 deaths and 100,657 recovered patients" [3]. Medical systems are facing a significant health crisis in terms of disposable protective materials [1]. One of the significant problems in this pandemic is the rapid spread of the SARS-Cov virus, which requires the use of multiple protective materials: gloves, surgical or respiratory masks, goggles, face shields, gowns, disposable protective materials for covering the head, neck, and lower limbs, including the feet [4]
