| Abstract Scope |
The potential of additive manufacturing to disrupt production of components from aerospace to medical devices has been demonstrated over the last 2 decades. The application of these innovative technologies has, however, been limited by the ability to qualify critical hardware which often exceeds 60% of the final part cost. In addition to process quality, novel ways to apply in situ monitoring for alloy development will be discussed aiding in the accelerated implementation of classical or novel alloys currently unattainable with the technology. The JHU/APL team has developed two novel on-axis sensors capable of measuring at between 500,000 and 11,000,000 Hz in hyperspectral ranges enabling direct measurement of real time temperature and spectral information. This technology paired with advanced calibration enables decoupling of wavelength and thermally dependent emissivity. The sensor paired with a FPGA enables real-time control of the laser parameters at high rates unlocking prescribed processing temperature set point. |
