This study aims to investigate the change in 3D printing fashion expression characteristics over the past 10 years by examining the early 3D printing fashion works of Iris van Herpen, a leader in the application of this technology to fashion. The research method consisted of a literature review and case analysis. In this research, 166 3D printing works from Iris Van Herpen"s collections (SS 2011 to SS 2021) were collected and analyzed. Iris van Herpen’s 3D printing fashion characteristics that appeared frequently were as follows: "retro futurism", "futuristic fantasy", "biomimicry", and "sustainability". "Retro futurism" was expressed as a mixture of handcraft and 3D printing technology based on chrome color. "Futuristic fantasy" was expressed in 3D printing fashion with fantastic images on the theme of humans in a virtual world with digital technology. "Biomimicry" was expressed as an innovative 3D printing fashion form inspired by nature with parametric technology. "Sustainability" was expressed in nature-friendly fashion by applying a parametric design method to upcycled materials.
