DURIP-Open architecture selective laser printing with unique capabilities
Abstract
We propose to purchase an Aconity3D MIDI+ metal 3D printing system specifically designed for research and development applications.The key feature of this system is its open architecture which allows the linkage between process parameters and performance to be studied and enables explorations into novel printing strategies and features, including: (i) operando modification of the process parameters based on feedback from in-situ monitoring sensors; (ii) tailoring microstructure and minimizing tensile residual stresses using beam shaping, in-situ heat treatment and laser peening, (iii) improving surface finish/ accuracy of printed parts using in-situ laser machining and dynamic laser focus adjustment; and (iv) developing new composites and functionally graded materials with improved combination of properties. Broadly, such studies aim to address key challenges of additive manufacturing (AM), from internal defects and anisotropic properties to limited fatigue life and quality control issues. Overcoming these challenges has the potential to transform AM technology for greater and more effective support of DoD#s mission.The PIs will utilize the equipment to aid in three current US Navy projects. The first project involves optimizing the post processing treatment of AM Ti-6Al-4V for fatigue performanceand the second project involves the development of a high throughput fatigue characterization methodology. Third project focuses ondesigning novel hybrid materials with enhanced properties using AM. Additionally, the proposed equipment will support further research priorities outlined in the Department of Navy s AM Implementation Plan, such as expanding materials for Naval AM use, establishing process-microstructure-property relationships, and developing in-situ and close-loop control for quality assurance. The printer will also be integrated into the PIs teaching and outreach activities. Along with the PIs, there are many other faculty members at Cornell who will haveaccess to the Aconity3D printer. The following examples demonstrate some of the research that will be enabled through this acquisition:# Manufacturing materials for applications in extreme environments# Manufacturing of cryogenic structures forquantum information systems# Manufacturing light weight, ultra stable structures# Manufacturing hardware components for space systems for in-orbit servicing, assembly, and manufacturing# Manufacturing implants for biomedical applications# Manufacturing hybrid robots which combine metal endoskeletons with soft actuators and sensors
