 Consequently, as the drum spins, most of the melt puddle remains held between the nozzle and the drum by surface tension.However, the melt on the very bottom of the puddle, which is in direct contact with the drum, rapidly solidifies into a thin ribbon.The solidified ribbon is carried away from under the nozzle on the drum's surface for up to 10° of rotation before centrifugal force from the drum's rotation ejects it.
