Gaussian beams produce a concentrated heat zone with linearly increasing peak temperature, while ring-shaped profiles shift the melting behavior and produce characteristic half-moon-shaped temperature distributions, with direct implications for process stability and beam shape selection in PBF-LB/M.</p>
