Elemental Analysis of Metal Powders and Metal Parts

2017/5/30Among the metal powders used for additive manufacturing are different types of steel and titanium. To check the quality and purity of these raw materials, suitable processes need to be implemented. The content of various "foreign" elements, for example, should be closely monitored to ensure a high-quality end product.

2020/7/29Laser Metal Deposition (LMD) is an additive manufacturing process whereby a laser is used to create a molten pool of metal on a substrate material; into which metal powder is deposited. Complex 2D geometries can then be constructed on the substrate surface and the process can be repeated for a number of layers to manufacture complex 3D components in a manner similar to

(IUCr) Ultrafast X

2018/7/4Currently, laser powder-bed fusion (LPBF) is the most popular method for manufacturing metal parts (Rosen, 2007; Campbell et al., 2011). In a typical LPBF process, a laser beam is scanned across a layer of powder with a thickness of around 50 m, which is laid on top of a substrate.

Technology Trends in Laser

2016/4/13So I decided to focus on two themes: laser-based metal additive manufacturing (AM); and design simulation for AM. In this post, I focus on the former and try to distill the trends I noticed across the laser-based metal AM system manufacturers that were present at the conference: Concept Laser, SLM, Renishaw, EOS and 3D Systems (listed here in the decreasing order of the time I spent at

Selective Laser Melting in Action

2015/12/14By applying additive design and manufacturing to an F1 cylinder head, FIT West Corp. used selective laser melting technology to significantly increase the surface cooling area throughout the part, while achieving great reduction in vibration and weight.

Nanomaterials

Additive manufacturing (AM) has become more prominent in leading industries. Recently, there have been intense efforts to achieve a fully functional 3D structural electronic device by integrating conductive structures into AM parts. Here, we introduce a simple approach to creating a conductive layer on a polymer AM part by CO2 laser

2015/12/29The production of metal parts via laser powder bed fusion additive manufacturing is growing exponentially. However, the transition of this technology from production of prototypes to production of critical parts is hindered by a lack of confidence in the quality of the part.

The next level of additive manufacturing

2020/3/25Making a standard machine part from metal powder using a laser system still looks a bit futuristic. Materials, processing time, and costs look a bit futuristic, too, and prohibit a broader introduction of additive manufacturing to regular job shops—but this may

Additive Manufacturing with Metals

To maximize the value of metal additive manufacturing, applications must be selected that leverage additive's technical advantages and economic structure while complying with its limitations. In this course, participants will learn the technical and economic criteria used to determine if a part is a candidate for this set of technologies.

Epitaxy and Microstructure Evolution in Metal Additive

Metal additive manufacturing (AM) works on the principle of incremental layer-by-layer material consolidation, facilitating the fabrication of objects of arbitrary complexity through the controlled melting and resolidification of feedstock materials by using high-power energy sources. The focus of metal AM is to produce complex-shaped components made of metals and alloys to meet demands from
