Biocement Printer

"Biocement" is a material byproduct of soil bacteria. When given the right substrate and conditions, the cells create calcium carbonate crystals, filling gaps in the substrate, binding it into a kind of cement. There are many opportunities to use the material to rehabilitate the habitats of decimated oyster populations.

Under the guidance of Professor Ryan Hoover, Dione Lee and I worked to retrofit a Z-Corp Spectrum Z510 powder-based 3D printer to work with sand (rather than the plaster-based powder of its original design), as well as hack the jetting system to harbor and distribute the soil bacteria rather than CMYK ink.

This project is still in a work in progress.
