Rajadevan; Dr. Hareharen K; and Mr. Navaneetha Krishnan S on October 13, 2026, for A Method And System For Closed-Loop Additive Manufacturing Of Metal Matrix Composite Components.
Inventors include Dr. L. Daniel Devaraj; Dr. Raj Mohan R; Dr. Raja Thiyagarajan; Mr. M. Rajadevan; Dr. Hareharen K; and Mr. Navaneetha Krishnan S.
The application for the patent was published on October 23, 2026, under issue no. 43/2026.
Abstract: A method and system for additive manufacturing of metal matrix composite components employ separately metered metallic and reinforcement feedstocks, a feedstock conditioning module (110), a deposition head (120), a controlled energy source (130), a sensor assembly (150) and a controller (160). A spatial reinforcement target is assigned to successive deposition regions, including controlled transitions between regions of different composition. During consolidation, thermal and optical process signals are acquired and evaluated using a calibrated relationship to estimate reinforcement retention and fusion quality. Where a process estimate deviates from an acceptable range, the controller selects a bounded adjustment of feed delivery, energy input, travel speed or a corrective remelting operation, subject to material-specific limits. Layerwise records associate process observations and corrections with deposition coordinates. The arrangement facilitates monitored fabrication of compositionally graded metal matrix composite components. Accompanied Drawing [FIGS. 1-2].
