Abstract
Conventional industrial‐scale production of metal powders generally occurs in large plants, where each batch sizes several hundred kilograms of powder. However, these production methods are economically impractical for manufacturers with lower demands, such as those involved in prototyping and developing new alloys for additive manufacturing. This study investigates wire arc atomizing as a viable alternative for producing metal powders that are specifically tailored to precise requirements and manufactured in a batch size of one. The wire melting process is controlled by modulating the electrical current, using pulsed and unpulsed DC. Arc power varies across a wide range to assess its impact on particle size distribution. Furthermore, the produced metal powders undergo comprehensive characterization and evaluation to determine their suitability for additive manufacturing, ensuring they meet specific application requirements.
This work explores the sputtering of additively manufactured (AM) materials for use in gridded ion source applications. The first part of the paper uses 316L stainless steel as an example to demonstrate that additively manufactured material does not exhibit adverse sputtering behavior, such as higher sputter yield, com...
Metal foams offer attractive properties for lightweight structures. This study presents the development of a powder metallurgical aluminum alloy intended for foamable wires that can be used in additive manufacturing processes such as wire and arc additive manufacturing (WAAM). Unlike established aluminum wrought al...

AZ31 magnesium alloy has been widely used in the aerospace and automobile industry due to its weight‐to‐strength ratio and good corrosion resistance properties. However, due to its low melting point and high reactivity, machining this alloy is difficult. Wire Electrical Discharge Machining (WEDM) is a noncontacting...
