As part of my master’s thesis, I developed an extrudable mycelium-based composite for additive manufacturing.
Alongside the material development, I created a Grasshopper-based workflow to generate and control extrusion paths for a low-viscosity, biologically active material, since there isn’t a standardized process to work and print with living materials.
The setup is based on contour slicing with adjustable layer height and path spacing. Due to slight deformation during deposition and possible shrinkage during drying, spacing and layer offsets were iteratively calibrated to maintain structural stability. If you’re interested in creating your own g-code slicer I can recommend the book “advanced 3D printing with grasshopper - clay & fdm”.
The aim was to treat material and process as one integrated system rather than separating geometry from fabrication.
