By Oleg Raykis Today there exist a number of technologies for additive manufacturing of components. The two most prominent types utilizing lasers for generating parts out of metals are either powder bed based solutions or direct energy deposition, often referred to as laser metal deposition. As a company Laserline focuses mainly on the second type. […]

Recap: CO2 vs. fiber laser shootout by Cincinnati Incorporated
In case you missed today’s CO2-vs.-fiber shootout by Cincinnati Incorporated using its 4,000-watt CL440 CO2 and CL940 fiber lasers to cut identical parts side by side, here’s a quick rundown. Performed at the company’s Customer Productivity Center in Harrison, Ohio, about 20 miles west of Cincinnati, this demonstration by the longtime LIA exhibitor used their machines […]
Sapphire Cutting with Pulsed Fiber Lasers
By Christoph Ruettimann, Noémie Dury and Markus Danner With almost 40 years of experience in precision processing of synthetic crystalline materials, Swiss laser manufacturer ROFIN-LASAG AG has developed a process for cutting sapphire glass, which is now increasingly used in mobile electronic devices and high-quality mechanical watches. Synthetic sapphire is a mono-crystalline aluminum oxide with […]
Local Laser Joining of Glass and Silicon
By Assi Hansen, Isamu Miyamoto, Tiina Amberla, Yasuhiro Okamoto One of the most employed material combinations in microtechnology is the glass-silicon pair. Since the huge growth of the microelectromechanical devices, sensors and micro-fluidic devices, bonding of this couple has become more and more critical issue. Many of these glass-silicon bonding processes, for example anodic bonding, […]
A Technical and Commercial Comparison of Fiber Laser and CO2 Laser Cutting
By John Powell, Alexander Kaplan Since the advent of commercial fiber and disk laser cutting machines, there has been a lot of controversy about the performance of these devices – particularly in comparison to their more established CO2 counterparts. In the early days, the sales staff promoting fiber technology would often declare that the new […]
