Feasibility of 3D Printing Applications for Highway Infrastructure Construction and Maintenance - Phase II

In recent years there has been a significant increase in interest in additive manufacturing (AM), yet AM is largely unexplored within infrastructure projects, although it can provide unprecedented new design capabilities. This project will explore the feasibility of additive repair technologies for real corroded steel beams ends. Different additive manufacturing solutions and repair technologies will be examined in the lab and on-site. Repaired beams will be tested for their strength, fatigue, and corrosion resistance. In addition the project will research the key factors related to the different repair technologies and equipment investigated that can impact the success of an attempted repair (Example: velocity of material being deposited). The research will be used to develop a list of suggested options for equipment and facilities that seem well suited for handling 3D printing applications and the associated qualifications testing of 3D printing repaired steel bridge beams.
