In laser powder-bed fusion processes, excessive metal powder is affected by high laser
energy input and contains spatter from the melt pool. Recycled powder therefore can have a …

During part fabrication by laser powder-bed fusion (L-PBF), an Additive Manufacturing
process, a large amount of energy is input from the laser into the melt pool, causing …

The freedom of design and ability to print complex parts have made laser powder-bed fusion
(LPBF) additive manufacturing (AM) a suitable alternative to traditional metal manufacturing …

This study reports on the impact of repeated powder recycling on the degradation of low
alloy steel powder in Laser Powder Bed Fusion. The average powder particle size increased …

Abstract In Laser Powder Bed Fusion (L-PBF) of metallic materials, costs and material yield
strongly depend on the ability to reuse powder efficiently, as a significant amount is not …

Abstract Metal Additive Manufacturing (AM) processes are developing quickly. These
processes have several attractive qualities, however, the quality of manufactured parts still …

AISI 316 L stainless steel is widely used as material to produce components by means of
additive manufacturing. To increase the circular economy, the powders are collected and re …

There is a clear economic benefit for the recycling of metallic powder during additive
manufacturing (AM). Laser powder bed fusion (L‐PBF) is one such AM process and …

Abstract Laser Powder-Bed Fusion (L-PBF), often called selective laser melting (SLM), is a
powder-bed fusion process in Additive Manufacturing (AM) that uses a laser beam to …

In selective laser melting (SLM) systems, a large portion of powder remains unconsolidated
and therefore recycling powder could make SLM more economical. Currently, a lack of …
