To　explore　the　application　of　the　latest　modern　industrial　technology　in　creative　decoration,　a　new　creative　decoration　design　concept　and　manufacturing　method　was　proposed　based　on　modular　and　3D　printing　lattice　structures.　First,　a　geometric　design　framework　for　expandable　monomeric　modules　and　a　mechanical　model　of　lattice　structure　connecting　monomeric　components　were　established,　and　their　mechanical　properties,　design　feasibility　and　manufacturability　were　analyzed.　Then,　the　design　and　manufacture　of　creative　apparel　were　realized　through　the　construction　of　creative　apparel　3D　models,　the　method　of　flat　structure　drawings,　and　3D　printing　technology.　The　results　show　that　the　proposed　monomer　module　design　can　expand　in　any　direction　in　space,　and　the　lattice　structure　connecting　monomers　can　maintain　a　stable　mechanical　structure　and　load-bearing　capacity　after　3D　printing　with　polylactic　acid　(PLA),　ensuring　creative　redesign　and　diverse　manufacturing　of　creative　apparel.　This　study　provides　a　new　interdisciplinary　integration　paradigm　for　the　new　generation　of　creative　apparel　design　from　materials　and　design　to　manufacturing　processes.　©　2024　Beijing　Institute　of　Clothing　Technology.　All　rights　reserved.
