During my Summer 2022 Co-op with Precision Environments, the head engineer had the idea to 3D Print scale models of various parts of a cleanroom as part of build proposals and trade show demonstrations.

The left two pictures are of the very first attempt. A basic cleanroom and plenum with fan filter units was mocked up and scaled down to fit on the print bed. As one part, the print did not perform very well. Small connections such as the corner between the walls and ceiling tiles did not scale well, and broke apart easily.

The right picture shows a print after some development of the process. Parts were exaggerated before they were scaled down, and a modular design was created. The walls were printed with a grid in the middle, and individual ceiling tiles (white rectangles), light fixtures (transparent rectangles), and fan filter units were printed to slot into the grid.

The modular design worked well, and served to demonstrate the plenum layout in a physical environment. Ultimately, however, my co-op came to an end before the project could be fully realized.
