## Description

The Trenton program seeks to enable underwater three-dimensional concrete printing (3DCP) through the development, refinement, and optimization of printable formulations and fabrication hardware. The overall goal of Trenton is to demonstrate that underwater 3DCP is possible.

Trenton objectives include the development of methodologies and chemistries to support the in situ manufacturing of concrete structures underwater in support of various Department of Defense (DoD) use cases including coastal infrastructure reinforcement and bridge repair. The Trenton program will require development and optimization of printing formulations and fabrication methods. Formulation includes all aspects related to the development and optimization of underwater 3DCP material chemistries.

Performers are expected to leverage and refine existing formulations to the maximum extent possible. Fabrication for Trenton will include aspects of hardware development that enable 3DCP from a land-based system into water at the bench scale. Performers are expected to leverage and adapt existing 3DCP hardware and adapting existing land-based 3DCP hardware for printing underwater.
