Enhancing the Functionality of a Hollow Scaffold Solid State Bioreactor via Computer Aided Design Optimization

Summary

This document describes the design and optimization of a Hollow Scaffold Solid State Bioreactor (HS-SSBR) aimed at mitigating greenhouse gas emissions, specifically methane (CH4), by converting it into useful products. Methane is a significant concern as it traps heat 21 times more effectively than CO2, with atmospheric concentrations increasing from 1219 ppb to 1842 ppb over 60 years. The project utilizes Computer Aided Design (CAD) and additive manufacturing (3D printing) to enhance the reactor's functionality, focusing on improved methane dispersion and media circulation. Key components were designed using SolidWorks 2024 and printed on a Formlabs 3L SLA printer with a layer thickness of 0.050 mm. An initial print of the reactor housing and lid took 60 hours, requiring a design modification to increase plate thickness by 2x, resulting in a successfully tested prototype.
