3D-printed, low-fired clay

How can 3D-printed stoneware structures support the restoration of coastal seaweed gardens and enhance community-based ecological interventions?

Seaweed forests are critical ecosystems: they act as major carbon sinks, regulate oceanic biodiversity, and sustain marine food webs. Yet, due to rising oceanic temperatures, pollution, and agricultural runoff leading to eutrophication, these underwater habitats habitats are rapidly declining. 

This project investigates how low-tech, biodegradable ceramic structures - called Seabombs - can serve as scaffolding for new seaweed growth. Seabombs are hand-sized, 3D-printed domes made from local clay. Their porous, textured surfaces feature geometrical pockets designed to hold seaweed spores, which are cultivated in marine nurseries before being introduced into the wild. 

Seabombs can be deployed in two ways: thrown into the ocean to sink naturally or strung vertically on ropes to optimize sunlight exposure. These forms mimic natural rock substrates, giving seaweed the anchorage it needs to thrive. Fired at low temperatures, the clay structures will gradually erode and reintegrate into the mineral cycle after their ecological role is fulfilled.

Community involvement is a central component. Local residents are invited to participate is all phases—from digging native clay and printing the forms using simple, site-specific clay printers, to pit firing and releasing the Seabombs into the sea. Their size is intentionally ergonomic, allowing each person to craft and contribute a single Seabomb—making coastal restoration tangible, personal, and collective.

This projects envisions a future where design serves not only for humans needs but also ecological healing, blending ancient craft, digital fabrication, and community care.
