“…The real object is built by depositing layer by layer on the table in a raster pattern according to the 3D printing parameters. Based on the data provided in many papers, [41][42][43] the most essential parameters are nozzle and working table temperature values, the height of the deposited layer of material, the defined number of solid layers, infill parameters like fill density, fill pattern, fill angle, and generation of the support structures. Mentioned parameters affect the geometric quality of manufactured objects and their mechanical properties.…”

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.
