CPE TPMS

CPE TPMS is a browser-based tool designed for early-stage screening of triply periodic minimal surface (TPMS) lattice structures in metal additive manufacturing. It addresses the specific challenge faced by engineers and designers when a full finite element analysis (FEA) or computational fluid dynamics (CFD) setup is premature, but a basic visual assessment is inadequate. The tool leverages closed-form models to rapidly analyze and expose key tradeoffs, such as stiffness, porosity, and potential conflicts with laser powder bed fusion (LPBF) manufacturing features, delivering results in milliseconds. The platform allows users to interactively explore three-dimensional lattice structures without requiring signup. CPE TPMS supports seven different TPMS lattice topologies and enables screening across thirteen LPBF-compatible metals. Users can adjust parameters like topology, density, and material to investigate how these choices affect structural properties and manufacturing feasibility. The tool provides idealized calculations for structural, thermal, and straight-passage fluid properties, helping users identify configurations that meet specific porosity and stiffness requirements while remaining manufacturable. CPE TPMS is intended for use during the early design phase, bridging the gap between an initial unsupported guess and the more detailed analysis provided by advanced simulation tools. It is particularly useful for quickly ranking lattice families and checking representative feature limits before investing in time-intensive FEA or CFD workflows. The tool is accessible directly through a web browser and does not require installation or account creation. Pricing and licensing details are not specified in the available information.
