This paper explores the development of a process for living 3D-printed mycelium objects through a low-tech, DIY-oriented fabrication approach. By transforming the extrusion system of common ceramic 3D printer, the project aims to lower technical and economic barriers to working with living materials. Rather than relying on highly controlled laboratory conditions the method emphasizes accessible tools, open-ended tinkering and hands-on experimentation. The workflow integrates locally available materials, simple mechanical modifications and basic and affordable environmental control to enable the growth of structurally stable, living 3D-printed mycelium objects. The project positions DIY mycelium printing as a practical entry point for artists, designers and researchers interested in biofabrication and contributes to broader discussions on democratizing living material technologies through low-tech and open practices.
