Fig. 2: Functional workflow of the Reac-Gen and Reac-Fab modules.

A Reac-Gen: generation and structural assessment of catalytic reactors through mathematical surface equations and structural metric analysis. XLSX (Excel) files are generated with structural metrics, and STL (Standard Tessellation Language) files are produced for subsequent 3D printing (3DP) in the Reac-Fab module. B Reac-Fab: machine learning (ML)-based printability validation, 3DP of the reactor, surface functionalization, and post-processing for catalytic applications.
