Designed at the SLU Center for Additive Manufacturing, this single-piece reaction chamber integrates pump inputs, a filter outlet, and a vacuum port to automate chemical processing, replacing expensive and fragile multi-piece glass assemblies.
Why PPS
The application required polyphenylene sulfide (PPS) due to its extreme chemical resistance and high thermal stability.
High-Temperature PPS Printing
Because standard desktop hardware caps nozzle temperatures below PPS processing levels, I assisted the lab in modifying the thermistor resistance values on a Bambu P1S to override firmware safety limits. This allowed the hotend to maintain the higher temperatures required to extrude the material cleanly.
