BeamWatch AM: Engineers Explain
Ophir has been honored with a 2018 Laser Focus World Platinum Innovators Award for BeamWatch AM®, the first non-contact laser beam monitoring system for additive manufacturing. In this video, Ophir engineers explain why the system is so revolutionary, how it works, and why it will help additive manufacturers.
When medical, aerospace, or other complex devices are produced in an Additive Manufacturing, powder-bed laser system, the product design requires the use of a variety of power levels. These different setting are a function of the structural integrity of the device under build, but also the efficiency of the design to avoid the use of excess materials, powders, and processing time. In a typical 1kw Additive Manufacturing laser, power levels during the build can range from 400W to 1000W, for either short or long durations. Therefore, profiling the laser beam at these different power levels is required. In a recent application test, a 1kW laser was provided at a variety of power settings from 400W to 1kW, in increments of 200Ws. The result of this diagnostic test demonstrated that as the power was increased, the ellipiticity (roundness) of the beam deteriorated. The change was not significant but demonstrated that in any build requiring a 360 degree range of the laser, the focal spot would be slightly larger in one direction and slightly smaller in a different direction, resulting in a major defect of the build. And since some of these builds can take 10’s of hours, finding out after the build that the laser is not round to specification is a costly result. These beam profiling diagnostics alerted the client to a potential problem BEFORE they went to build product, avoiding costly mistakes.
