TRENTON PROGRAM OVERVIEW

 

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's objectives include the development of additive construction 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 the 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 and must be mindful to avoid potentially toxic materials while developing formulations. 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 land-based 3DCP for printing underwater. The inclusion of structural reinforcement to 3DCP structures is not a requirement for Trenton phase 1. However, discussions regarding solutions for adding reinforcements and future integration are welcomed.

EVENT PARTICIPATION

Eligibility

Proposers Days are only open to registered potential proposers, i.e., the events are closed to the general public and media. For this particular program, Proposers Day registration is open to potential proposers who are U.S. citizens, U.S. permanent residents, and foreign nationals.

All registrants who are not U.S. Citizens must complete and submit either a DARPA Form 60 (U.S. Permanent Resident and Foreign National Visit Request — e.g., industry or academia) or an Official Visit Request (foreign government personnel, only) through the Embassy based in Washington, DC, no later than 1:00 PM ET on October 4, 2024. Form 60 submission instructions will be provided in the registration confirmation email. Contact your Embassy staff for assistance in submitting the Official Visit Request. 

Registration

There is no registration fee for the Proposers Day. The registration deadline is 1:00 PM ET on October 4, 2024 or when capacity is reached, whichever comes first.

Advance registration is required for virtual attendance. NOTE: All persons wishing to attend the webinar must register (whether viewing alone or as part of a group). 

Registration received in excess of 350 individuals for ZoomGov may be added to a waitlist for the webinar. If slots become available due to cancellations, the slots may be filled on a first come, first served basis from the waitlist.
