Architected materials have emerged as a powerful design paradigm in which mechanical and multifunctional properties can be programmed primarily through geometry features rather than constituent composition. However, the growing diversity of architected topologies and design strategies has created a need for unified computational tools capable of handling multiple architectural classes, spatial variations, and hybrid designs within a single framework. This contribution introduces Top6 Meta Studio, a Python-based computational framework as a software for the rapid generation of architected material and structural designs for additive manufacturing and numerical modeling. The framework integrates three primary architectural families— strut-based lattices, triply periodic minimal surface (TPMS) architectures, and stochastic spinodal designs—together with three derivative design classes enabled through secondary operations: functionally graded architectures, hybrid multi-morphology designs, and interpenetrating phase composites (IPCs). All design classes are implemented within a common implicit modeling package, allowing consistent control of topology, relative density, and spatial variation while enabling smooth transitions between different architectural designs. Top6Meta supports the generation of both architected materials and structural components such as beams, plates, sandwich structures, and columns, thereby bridging mesoscale topology design with macroscale structural applications. The software employs a modular architecture that supports both scripted and graphical workflows, while selective multicore processing can be used to accelerate computationally intensive geometry-generation tasks. In addition, the framework enables direct export of single- and multi-phase geometries in each design module for additive manufacturing and numerical simulation. By consolidating diverse architected-material design strategies into a single extensible platform, Top6Meta provides a flexible and efficient environment for rapid prototyping, parametric exploration, and systematic investigation of next-generation architected materials and metastructures.
