“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.

Under the guidance of Professor Ryan Hoover, we are attempting to use the material to rehabilitate the habitat of the decimated Chesapeake Bay Oyster population.

My role in the project (along with Dione Lee), is 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 bacteria rather than CMYK ink.

Feel free to reach out if you have any questions.
