nLight releases laser for AM

nLight Inc. introduced its AFX-1000 fiber laser for the metal additive manufacturing (AM) market. Leveraging programmable laser technology, the high-power fiber laser can switch between a single-mode beam and other beam profiles without the use of free space optics. The beam shaping function is performed entirely inside the laser. Discrete beam profiles can be selected on the fly as quickly as 30 times per sec., offering new degrees of freedom to control melting and solidification rates, physical microstructure and thermal strain that can lead to stress fractures.
