Bra Underwire Customization With 3-D Printing

Abstract

In the current research, we aimed to investigate whether customized 3-D underwires improve bra performance. The first experiment was designed to study whether customized 3-D printed underwires provide significant benefits over conventional wires. Customized 3-D underwires were produced following individual breast root shapes and compared with conventional underwires through wear trials. According to the empirical data, pressure was significantly reduced with the customized underwire, and performance improvement was more evident with wearing sensations of support and comfort. In the second experiment, we varied the length of the customized underwires and observed how the length of underwires influenced bra performance. More pressure was found in the outer region of the longest underwires than the medium-length wires but support and comfort sensations did not have noticeable changes depending on the wire length. As illustrated in this research, advanced 3-D technologies could contribute to product engineering and customization in the apparel industry.

Application of Digital Technology to the Construction of the Fashion Design System under Mass Customization Mode

“…When customized products are more and more popular, the traditional manual customization mode cannot meet mass production of customized products. However, purchasing and pursuing customized and limited products have become an inevitable trend of the times [6]. In the reform process of mass production of customized products, digital technology (DT) gradually attracts the attention of scholars because the use of DT to produce customized products can better highlight the personality display consumers' personality and achieve mass production [7].…”

A novel optimization approach to minimize aggregate-fit-loss for improved breast sizing

“…19 Each company has their own rules for converting the bust-underbust difference into letter graded cup sizes, and the offset can range from 0 to 6 inches. 20 Practices of vanity sizing, where companies deliberately alter size labels to flatter smallerbusted consumers by indicating that bigger than actual sizes are the right fit, exacerbate the inconsistency. 21 Moreover, the current bra sizing systems also receive criticisms for their ambiguity in measurement definition and inadequacy in approximating breast volume.…”
