By Professor Bill Steen From the early beginnings of LAM has come a process which is developing in many directions. Through the variety of ways in which the laser can construct three dimensional objects it has been established that designers can now shape both the outside and the inside of a casting in detail not […]

Laser Surface Treatment and Additive Manufacturing – Basics and Application Examples
By: Dr. Ingomar Kelbassa Laser Surface Treatment and Additive Manufacturing have a strong impact on classical manufacturing and repair tasks addressing markets such as turbo machinery, aeronautics, automotive, off-shore and mining as well as tool, die, and mold making and life science.
High Power Direct Diode Laser Cladding of Stainless and Nickel Alloys
By: Dr. Gerald Bruck and Brandon Shinn Siemens Energy Inc. A four kilowatt high power direct diode laser is demonstrated to clad stainless (UNS S41000) and nickel based (UNS N06002) alloys. Trials are conducted using pre-placed as well as argon fed filler metal powders deposited on matching alloy substrates. Parametric tests are performed to define […]
Beam Shaping Optics for Additive Laser Technologies
By: Dr. Alexander Laskin Molecular Technology (MolTech) GmbH, Berlin, Germany Homogenizing of intensity profile of laser beam brings to additive laser technologies effects that improve the performance of those technologies comparing to what can be achieved with “usual” non-uniform laser beams: the processes become more stable, less tough positioning tolerances make the technologies easier to […]
Internal Bore Laser Cladding
By: Paul Colby Background Bimetallic cylinders are pressure vessels functioning as a component in a system to melt plastics with abrasive additives such as glass and minerals. These vessels have been manufactured the same way since the 1950‘s. Xaloy has developed and patented a new technology that will improve the useful life of bimetallic cylinders […]
