Project Summary

This project aims to extend the life of transportation facilities by using 3D printed molds to manufacture thermoplastic composite molds that can be used as formworks for precast concrete. This project addresses the need to develop durable and cost-effective forms and tooling for precast concrete parts used in transportation.

Sponsors:

Office of the Assistant Secretary for Research and Technology, University Transportation Centers Program, Department of Transportation
University of Maine, Maine Department of Transportation

Implementation of Research Outcomes:

Large-scale railroad bridge ballast retainer formwork at American Concrete Ind. plant in Veazie, Maine.

3D printed form of at the Unistress Corp. precast concrete plant in Pittsfield, MA.

Impacts and Benefits of Implementation:

a. DOTs will be able to specify durable and cost-effective thermoplastic composites with optimized designs using large-scale 3D printings for precast concrete forms and tooling.
b. Optimized 3D printed forms will increase the longevity of precast concrete elements and parts.
