3D digital technology in upcycling apparel design: the creation of a modular redesign system and designer perspectives

Despite advancements in sustainable apparel design, upcycling practices still face challenges limiting creativity and efficiency. This study develops a Modular Redesign System (MRS) using 3D digital technology to improve the upcycling process. The MRS was created with CLO3D and Aftereffects, producing ten redesign samples and demonstration videos. In-depth interviews with South Korean upcycling apparel designers were conducted to assess the system’s perceived effectiveness and explore key issues in upcycling design. The MRS involves four stages: Selection, Virtualisation, Virtual Ideation, and Construction and Fitting. Findings highlight the MRS’s ability to enhance ideation, reduce material waste, and save time and costs, offering practical solutions to current challenges in apparel redesign. The MRS also shows potential for mass customisation, serving as an effective communication tool for personalised upcycling services. This study bridges a gap in the literature by integrating 3D virtual simulation with modular design to advance sustainable and efficient upcycling practices.
