Here we present the design strategy for Cu2Se thermoelectric materials for high-temperature power generation using a combination of finite element modelling and 3D printing. The macroscopic geometries and microscopic defects in Cu2Se materials are precisely engineered by optimizing the 3D printing and post-treatment processes... Herein, we develop a generalised microscale 3D printing method for the production of purely inorganic nanocrystal-based porous materials. Our process is designed to solidify all-inorganic nanocrystals via immediate dispersibility control and surface linking-induced interconnection in the nonsolvent linker bath and thereby creates multibranched gel networks... Herein, we report a generalised direct optical printing technique to obtain functional metal chalcogenides via digital light processing. We developed universally applicable photocurable chalcogenidometallate inks that could be directly used to create 2D patterns or micrometre-thick 2.5D architectures of various sizes and shapes... Here, we answer the above questions by establishing a theoretical framework that systematically analyzes the power generation in 3D TE materials across diverse thermal boundary conditions. We developed theoretical models for 3D TE systems under eight operating conditions, incorporating combinations of the Dirichlet, Neumann, and Robin boundary conditions. Based on this framework, we introduce a geometric factor (G factor) as a universal parameter to guide the optimization of the TE leg design...... Here, we introduce a universal design framework that integrates topology optimization (TO) with additive manufacturing to systematically derive high-efficiency thermoelectric 3D architectures. By formulating an optimization problem to maximize power generation efficienc
