Is Your Laser Delivering Consistent Metallurgy?

 

Laser processes, including such additive manufacturing (AM) techniques as Selective Laser Sintering (SLS) and Selective Laser Melting (SLM), require consistent energy be delivered to the material that is to be transformed. The laser beam spot size and intensity must be maintained within a finite window.

 

How do you know the laser is delivering exactly the beam that's needed?

 

Introducing Ophir® BeamWatch® AM, the industry's first non-contact laser beam monitoring system for additive manufacturing. This lightweight, compact system is designed for real-time measurement of focal shift during laser startup of powder bed fusion manufacturing processes.

 

• Measure key beam size, position, and quality parameters, including focus spot
   size and beam caustic, to more easily determine when beam is aligned and in
   focus.
• Only system able to show focal shift over time, providing more consistent
   metallurgy.
• Tabular and 2D/3D views provide quick and realistic displays of laser
   characteristics.
