This investigation analyzes the main contributions that additive manufacturing (AM) technology provides to the world in fighting against the pandemic COVID-19 from a materials and applications perspective. With this aim, different sources, which include academic reports, initiatives, and industrial companies, have been systematically analyzed. The AM technology applications include protective masks, mechanical ventilator parts, social distancing signage, and parts for detection and disinfection equipment [ 1 ]. There is a substantially increased number of contributions from AM technology to this global issue, which is expected to continuously increase until a sound solution is found. The materials and manufacturing technologies in addition to the current challenges and opportunities were analyzed as well. These contributions came from a lot of countries, which can be used as a future model to work in massive collaboration, technology networking, and adaptability, all lined up to provide potential solutions for some of the biggest challenges the human society might face in the future.

“…[7] Likewise, various groups have designed and tested 3D-printed nasal swabs with different materials, designs, and manufacturing methods, showing promising results and potential benefits over traditional swabs. [8][9][10][11][12][13] Clinical studies have found that 3D-printed swabs have a 94% similarity to standard swabs, indicating their potential for use in medical contexts. [14] Meanwhile, it is equally important to ensure mechanical properties for patient comfort and safety.…”

Additive manufacturing has proven to be a reliable and quick method for creating devices and tools, particularly during disruptions to supply chains. One example is 3D printed nasal swabs with tubular structures that require robust mechanical strength while maintaining adequate flexibility. However, there is a lack of detailed understanding on the mechanical response of tubular structures under torsion loading. The goal of this work is to understand the torsional behavior of a new group of 3D printed tubular metamaterials. We used the idea of mechanical metamaterials and started with a simple rectangular lattice. Two main design methods were used: reinforced lattices and compliant lattices. First, we added diagonal reinforced beams to enhance the torsional rigidity, inspired by the lattice structure of sea sponges. Furthermore, we added pre‐buckling to the straight beam, creating a flexible structure that increases the maximum torsional resistance. Our experiments demonstrated the sponge‐inspired design exhibits enhanced stiffness approximately 21 times that of baseline tubular designs. Moreover, the strength and toughness of the sponge‐inspired design are approximately 2.5 and 3 times higher, respectively. By curving the straight beam, we created a set of compliant tubulars that improve flexibility. The torsional angle is increased by at least 2.7 times, while the torsional toughness can reach up to 17 times. Numerical simulations have demonstrated that introducing triangulation into the diagonal reinforced lattice can enhance its stiffness and stability. This is achieved by effectively distributing stress, thereby contributing to structural rigidity. By curving a straight beam and constructing a compliant lattice, stresses are more evenly distributed over a larger area, allowing for greater deformation of the beam without causing failure. Using these two design strategies helps in creating tubular metamaterials with varied applications. Industries requiring high torsional resistance, such as aerospace parts and the automotive industry, can particularly benefit from these materials. They also offer advantages for sectors that need enhanced flexibility, like wearable electronics and soft robotics.This article is protected by copyright. All rights reserved.

The paper describes the design concept and findings from technological and initial clinical trials conducted to develop a helmet for non-invasive oxygen therapy using positive pressure, known as hCPAP (Helmet Continuous Positive Airway Pressure). Methods: The study utilized PET-G filament, a recommended material for medical applications, along with the FFF 3D printing technique. Additional technological investigations were performed for the production of fitting components. The authors proposed a parameter identification method for 3D printing, which reduced the time and cost of the study while ensuring high mechanical strength and quality of the manufactured elements. Results: The proposed 3D printing technique facilitated the rapid development of an ad hoc hCPAP device, which was utilized in preclinical testing and treatment of Covid-19 patients, and yielded positive results. Based on the promising outcomes of the preliminary tests, further development of the hCPAP device's current version was pursued. Conclusion:The proposed approach offered a crucial benefit by significantly reducing the time and costs involved in developing customized solutions to aid in the fight against the Covid-19 pandemic.
