A Review of Metal Fabricated with Laser‐ and Powder‐Bed Based Additive Manufacturing Techniques: Process, Nomenclature, Materials, Achievable Properties, and its Utilization in the Medical Sector

“…[100] A common approach to characterize the fabrication process is by the applied energy density of the core irradiation, volumetric energy density VED ð Þ ¼ laser power  exposure time layer thickness  hatch distance  point distance ; It has been shown that the applied energy density correlates with numerous properties, such as relative density, tensile strength, hardness, and surface roughness. [10] An overly large hatch distance results in an insufficient bonding between subsequent scan tracks and consequently, in poor mechanical properties. [105][106][107][108][109][110] The hatch distance, for example, is the distance between two neighboring scan tracks and thus, greatly corresponds with the remolten fraction of the previously fabricated scan track, ensuring a proper connection among the single weld beads of a layer.…”

“…This changes rapidly when moving on toward the fabrication of directly applicable components. [8][9][10] Given this, the knowledge of peculiarities of AM fabricated parts, their material properties, directional characteristics, and the resulting challenges in the design are of great importance. [7] In aerospace applications, the main intention is to enhance the strength to weight ratio of components, allowing aeroplanes to become lighter and thus, more efficient and versatile.…”

Laser Welding of BTi-6431S High Temperature Titanium Alloy

“…Titanium alloys are widely used in the aerospace field to manufacture important structures which are used at high temperatures and/or under complex stress states, due to unarguable properties such as excellent corrosion resistance, high specific mechanical resistance, and excellent high temperature performance [1,2]. However, with the development of high performance flying technology, more strict requirements are put forward for the performance of titanium alloys in the aerospace field [3].…”
