Resumo

A pandemia trouxe obstáculos sem precedentes. Um dos desafios críticos foi a carência no abastecimento de Equipamentos de Proteção Individual (EPIs). Para atender à demanda, a manufatura aditiva surgiu como uma solução viável para resolver a falta de alguns equipamentos. Máscaras impressas em 3D foram desenvolvidas para combater a falta do mercado, porém ainda está para ser superada a produção do elemento filtrante. Este estudo documenta a investigação que busca a viabilidade da aplicação da técnica de fundição de plástico por meio do centrifugal melt spinning, que é uma forma possível de ser replicada entre os processos existentes. De conceito simples e similar ao de fabricação de algodão doce. O objetivo é apontar possíveis caminhos do uso da fabricação e reciclagem distribuída e adaptação de infraestrutura local na manufatura de filtros viáveis, comparando-os com os gerados a partir de métodos tradicionais.

Abstract

The pandemic has brought unprecedented obstacles. One of the critical challenges was the shortage of Personal Protective Equipment (PPE). To meet the demand, additive manufacturing has emerged as a viable solution to solve the shortage of some equipment. 3D-printed masks have been developed to combat the market shortage, but the production of the filter element has yet to be overcome. This study documents research into the feasibility of applying the plastic casting technique using centrifugal melt spinning, which is a possible way of replicating existing processes. The concept is simple and similar to cotton candy manufacturing. The objective is to point out possible paths for the use of distributed manufacturing and recycling and adaptation of local infrastructure in the manufacture of viable filters, comparing them with those generated from traditional methods.
