Choosing the Correct Laser Beam Characterization System for Your Additive Manufacturing Chamber

Today, additive manufacturing (AM) is being used on industrial scales and not only to print prototypes, so the quality of the produced parts and the repeatability of the process are now crucial. A key factor in the quality of the finished AM product is the condition of the laser and optical components used. To ensure…

Three Ms for Laser Cutting Performance: Monitoring, Measuring, and Maintenance

Maintaining performance throughout a laser cutting or welding process is critical to achieving high quality results and preventing damage to materials. This is best done by monitoring the process and measuring certainlaser parameters, to identify issues and allow for preventative maintenance. Laser cutting and welding performance When it comes to laser cutting and welding, maintaining…

Green and Blue Laser Welding

Laser welding, cutting, or cladding has become increasingly popular and, in most cases, has been performed at the NIR wavelength region. However, NIR lasers are less efficient for copper processing due to hig­h reflectivity and therefore low energy absorption. Copper absorbs just 5% of the laser energy at 1070nm, but up to 40 % at…

Not Too Hot, Not Too Cold: Sensor Fusion Analysis in Additive Manufacturing Laser Processing

Sensor fusion is a concept that merges – or fuses – data from various sensors to create a more complete understanding of a laser’s performance. It’s particularly important in additive manufacturing using laser powder bed fusion, a 3D printing process that makes metal parts. Metal powder is subjected to powerful laser beams, creating solid layers…

Why and How to Profile Challenging Laser Applications

We introduce three techniques for monitoring the critical characteristics of the beam as the laser is used in three very different applications: (a) VSCEL / Laser Diode Mode and beam divergence, (b) Additive Manufacturing lasers used is 3D SLM / SLS, and (c) Fiber welding / heat treating / cleaning lasers. We will discuss three…

Maintain Proper Laser Beam Parameters for Additive Manufacturing

Additive manufacturing (AM), including selective laser melting (SLM) and 3D printing, relies on its laser source to properly manufacture 3D-printed parts. The laser is at once the most essential element of the system, and the most vulnerable to degradation. Here are some of the malfunctions that can occur with an unmonitored laser system: Optical pass…
