Laser Additive Manufacturing for Aerospace Prototypes
By: Agnes Klucha Pratt & Whitney Aerospace prototyping is a way to realize the vision of freeform fabricated metal additive manufactured parts on aerospace production engines, gain acceptance for additive manufacturing and change perceptions of what is possible. The freeform fabrication of laser additive manufactured metal parts is of prime interest in aerospace prototyping since […]
Overview of Laser Additive Manufacturing in China
By: Minlin Zhong Tsinghua University The booming Chinese economy has created a favorable environment for the research, development, application and market in the area of high-power lasers and especially laser additive manufacturing (LAM) in China. In a so-called “world manufacturing center,” laser additive manufacturing, as a modern advanced manufacturing technology, plays an important role in […]
New Stainless Powders for Laser Cladding
By: Ingrid Hauer North American Hoganas New investments into laser cladding as well as wear and corrosion testing equipment have lead to the expanded use of stainless steels. Latest developments show these lower cost alloys are able to yield comparable physical properties to many of the traditional Ni-based and Co-based alloys commonly used today.
In-situ Composition Analysis of Direct Metal Deposition Process using Optical Emission Spectroscopy of Laser Induced Plasma
By: Lijun Song and Jyoti Mazumder Center for Laser Aided Intelligent Manufacturing, University of Michigan The ability to monitor the elemental composition in real time for laser aided rapid manufacturing is essential for both estimation of elemental losses and elemental control. Traditionally X-ray fluorescence (XRF) and energy dispersive X-ray spectroscopy (EDS) have been widely used for […]
