- Advanced technologies for shoe sole productionPublication . Spahiu, Tatjana; Almeida, Henrique; Ascenso, Rita M. T.; Vitorino, Liliana; Marto, AnabelaAdvanced technologies for modelling and production are an important part in the whole process of product manufacturing. These advancements have changed the way of product development and play an important role in customization. In the footwear industry, as in any other industry, the use of these technologies is widely spread. Footwear comfort is one of the main selection criteria for purchase. Considering this fact, a case study of different steps for shoe designing according to individual foot shape will be presented. Taking into consideration the aesthetics of the sole and in a more sustainable view, through topological optimization reducing of material wastage for sole production will be presented. By means of the topological optimization in the shoe design process, sole optimization is realized. As a part of personalization, feet’s plantar pressure maps taken from 1 participant gave a better explanation of weight distribution of each foot. Following, sole personalization according the plantar pressure maps for each foot gives the possibility to obtain the best least material design according to the feet’s pressure while maintaining biomechanical performance.
- Fashion Products Through Digital Manufacturing - A Case Study With FDM TechnologyPublication . Spahiu, Tatjana; Almeida, Henrique; Manavis, Athanasios; Kyratsis, PanagiotisWe live in a digital world comprising the use of computer systems applicable to every process of manufacturing. Digital manufacturing is present in almost all areas of production by linking systems and process required from conceptualization to the final product. Through the use of digital manufacturing fashion products are designed and manufactured. Case studies of using the tools of 3D CAD software modeling to create novel products as textile structures, accessories and shoes parts as heels are presented. Taking inspiration from several sources, customized models are designed and with the great power of additive manufacturing as FDM technology, a non-expensive compared to the other types of additive manufacturing technologies, is implemented in the manufacturing of 3D CAD models. Without restriction on design, 3D models generated form CAD software are print directly by avoiding other process related to traditional manufacturing. The rise of new technologies in digital manufacturing releases new opportunities for companies to foster productivity, customization and sustainability.
- Optimization of shoe sole design according to individual feet pressure mapsPublication . Spahiu, Tatjana; Almeida, Henrique; Ascenso, Rita M. T.; Vitorino, Liliana; Marto, AnabelaInnovative technologies are shaping the future of product development in many industries. From the wide range of applications apparel industry as garments, footwear and accessories has involved advanced technologies in different steps of product development. The focus of companies is quality and fit of products, especially for footwear products, where fit is one of the most important elements for the wearer. This is strongly related with comfort and poor fit leads to foot injuries. Considering this fact, a case study of different steps for shoe designing according to individual foot shape will be presented. Taking into consideration the aesthetics of the sole and in a more sustainable view, through topological optimization reducing of material wastage for sole production will be presented. By means of the topological optimization in the shoe design process, sole optimization is realized.
