Mold Printer: Improvements in creating living, self-revealing artworks using a modified 3D printer

Student thesis: Master's Thesis

Abstract

This thesis presents the ongoing development of a unique method for creating living,
self-revealing artworks using a custom-built, low-cost DIY bioprinter. The bioprinter,
adapted from off-the-shelf 3D printer hardware, deposits non-pathogenic mold spores
onto a growth medium to produce images that develop over several days. Unlike traditional agar art, the process does not require an incubator, allowing the artworks to be
displayed openly throughout their lifecycle. The introduction of new calibration tools has
enhanced the reliability and accuracy of the printing process, while keeping the system
affordable and accessible. Reliable creation of multi-mold images has opened the doors
to more elaborate and vibrant designs. We have introduced two color mutants of Aspergillus nidulans into the project and re-evaluated two easily accessible fungal strains,
Penicillium roqueforti, and Geotrichum candidum. Our approach remains safe and accessible, even for hobbyists without specialized equipment, and this work contributes to
the growing intersection of Bio-Art, science communication, and Bio-Human-Computer
Interaction (Bio-HCI). Through this project, we aim to encourage interdisciplinary exploration and broaden the potential of living art as both a creative and educational
medium.
