Face Shield Frame Material Planning Using Quality Function Deployment

Abstract

The inspiration for the research was a customer request for 3D printing of face shield frames during the COVID-19 pandemic. In this context, but also due to the possibilities of relatively cheap 3D printing of various products, a large amount of waste started to be generated that needed to be disposed of. The overall aim of the research was to contribute to the development of new products printed using the 3D Fused Filament Fabrication (FFF) technology from thermoplastic materials, with a view to maximizing the quality level and minimizing the environmental footprint and cost of production. A modified Quality Function Development (QFD) methodology was applied, supplemented by a material planning matrix and a 3D model planning matrix which is the scientific contribution of the research. According to an extended QFD methodology taking into account the particular characteristics of 3D printing quality control and material selection decisions in terms of minimizing environmental impact, frames were printed from biodegradable PHA Biowood 3D Rosa filament. Waste management improvement is proposed by using filaments from biologically degradable materials or recycled filaments.
