Cross-contamination by people movement is a serious problem in food and health environments. This is caused by the need for workers to move around different areas of the workspace, carrying bacterial agents in their shoes from one place to another. The disinfection methods commonly used do not completely eliminate the microorganisms, mainly due to the porous structure of the outsole of the footwear used. This document presents a new prototype of functional footwear for these environments, whose outsole design has been functionalised in such a way that it is presented through two independent fundamental elements: a main body made of EVA by injection; and a footprint, in direct contact with the pavement, which can be exchanged for another pathogen-free footprint when deemed necessary, avoiding the transfer of microorganisms when the user moves from one place to another. This footprint is manufactured by fused-filament 3D printing, using thermoplastic polyurethane (TPU) material additivated with silver nanoparticles (AgNPs), which give it antimicrobial properties. The industrial design of these two elements has been carried out with the aim of guaranteeing a solid attachment between them, but at the same time allowing the replacement of footprints in a simple and fast way, and without requiring the use of additional auxiliary elements. Through the experimentation phase, the antimicrobial and cytotoxic properties of the developed footprint have been analysed, and the physical-mechanical properties of the footprint as a whole have been evaluated according to various standards.

使用增材制造技术对具有抗菌性能的鞋外底进行设计和功能化:工业应用

在食品和健康环境中,人员流动造成的交叉污染是一个严重的问题。这是由于工人需要在工作区的不同区域四处移动,将细菌在他们的鞋子中从一个地方搬到另一个地方。常用的消毒方法不能完全消除微生物,这主要归因于所用鞋类的外底的多孔结构。本文档介绍了针对这些环境的功能鞋的新原型,其外底设计已通过以下两个独立的基本要素进行了功能化:EVA注射成型主体;和与人行道直接接触的脚印,在必要时可以更换为另一个无病原体的脚印,避免当使用者从一个地方移到另一个地方时微生物的转移。该足迹是通过熔融丝3D打印制造的,使用的热塑性聚氨酯(TPU)材料加上银纳米颗粒(AgNP)使其具有抗菌性能。已经对这两个元件进行了工业设计,以确保它们之间的牢固连接,但是同时允许以简单和快速的方式更换脚印,而无需使用附加的辅助元件。在整个实验阶段,已对所开发足迹的抗菌和细胞毒性特性进行了分析,并根据各种标准对足迹整体的物理机械性能进行了评估。该足迹是通过熔融丝3D打印制造的,使用的热塑性聚氨酯(TPU)材料加上银纳米颗粒(AgNPs)使其具有抗菌性能。已经对这两个元件进行了工业设计,以确保它们之间的牢固连接,但是同时允许以简单和快速的方式更换脚印,而无需使用附加的辅助元件。在整个实验阶段,已对所开发足迹的抗菌和细胞毒性特性进行了分析,并根据各种标准对足迹整体的物理机械性能进行了评估。该足迹是通过熔融丝3D打印制造的,使用的热塑性聚氨酯(TPU)材料加上银纳米颗粒(AgNP)使其具有抗菌性能。已经对这两个元件进行了工业设计,以保证它们之间的牢固连接,但是同时允许以简单和快速的方式更换脚印,而无需使用附加的辅助元件。在整个实验阶段,已对所开发足迹的抗菌和细胞毒性特性进行了分析,并根据各种标准对足迹整体的物理机械性能进行了评估。赋予其抗菌特性。已经对这两个元件进行了工业设计,以确保它们之间的牢固连接,但是同时允许以简单和快速的方式更换脚印,而无需使用附加的辅助元件。在整个实验阶段,已对所开发足迹的抗菌和细胞毒性特性进行了分析,并根据各种标准对足迹整体的物理机械性能进行了评估。赋予其抗菌特性。已经对这两个元件进行了工业设计,以确保它们之间的牢固连接,但是同时允许以简单和快速的方式更换脚印,而无需使用附加的辅助元件。在整个实验阶段,已对所开发足迹的抗菌和细胞毒性特性进行了分析,并根据各种标准对足迹整体的物理机械性能进行了评估。
