The personal protective equipment fabricated via 3D printing technology during COVID-19

Abstract

COVID-19 has been spread in more than 220 countries and caused global health concerns. The supply chain disruptions have abruptly affected due to the second wave of COVID-19 in various countries and caused unavailability and shortage of medical devices and personal protective equipment for frontline healthcare workers. Three-dimensional (3D) printing has proven to be a boon and revolutionized technology to supply medical devices and tackle the situation caused by the COVID-19 pandemic. The diverse designs were produced and are currently used in hospitals by patients and frontline healthcare doctors. This review summarises the application of 3D printing during COVID-19. It collects the comprehensive information of recently designed and fabricated protective equipment like nasopharyngeal swabs, valves, face shields, facemasks and many more medical devices. The drawbacks and future challenges of 3D printed medical devices and protective equipment is discussed.

Scientometric Review for Research Patterns on Additive Manufacturing of Lattice Structures

“…Additionally, it illustrates the impact of several events, such as the COVID-19 pandemic and the global decline in the price of oil per barrel in the years 2016–2017. The authors propose that these two worldwide events have an impact on the volume of publications for additive manufacturing on lattice structures, especially COVID-19 [ 169 , 170 , 171 , 172 , 173 , 174 , 175 , 176 , 177 , 178 , 179 ]. The production of high-caliber research articles has been significantly influenced by the recent worldwide COVID-19 epidemic in 2020–2021 and national lockdowns that happened in over 80% of countries globally for many months due to the challenge of finding COVID-19 controls such as the use of 3D printed face shields [ 9 , 120 , 180 , 181 , 182 , 183 , 184 , 185 , 186 , 187 , 188 ].…”

Current trends, applications, and challenges of coatings on additive manufacturing based biopolymers: A state of art review

“…However, due to distinctive advantages of additive manufacturing (AM), [60] it has gained attention of researchers. [61,62] The technique involves faster part building [63] and results in production of customized implants with minimized waste material as manufacturing is done layer by layer. [64] The three dimensional model of the implant is made in designing software, which is then tessellated to form Standard Tessellation Language (STL) file and printing of part takes place with deposition of each layer.…”

Post‐yielding fracture mechanics of 3D printed polymer‐based orthopedic cortical screws

“…Three dimensional (3D) printing technology is currently employed in orthopedic surgery, dental surgery and cardiovascular surgeries for surgical planning, 3D scanning, virtual planning, patient-specific prosthetics and customized implants fabrication. [13][14][15][16][17][18][19] It can provide a porous lattice structure utilized in orthopedics for personalized implant design and porous screw fabrication. Korde et al [20] used 3D printing technology to fabricate honeycomb-patterned composites.…”
