Characterization of machine noise signals during L-PBF for online monitoring using gas-borne acoustic emission

Autor: Moore Karabo, Kouprianoff Dean, Yadroitsava Ina, Yadroitsev Igor

Publikováno v: MATEC Web of Conferences, Vol 406, p 05004 (2024)

The metal laser powder bed fusion (L-PBF) technology uses a layer-by-layer manufacturing technique. During the build process, various acoustic emission (AE) signals are emitted by the machine components inside the build chamber: which include AE sign

Developing a Ti6Al4V specimen to induce residual stress deformations and cracks for use in metal additive manufacturing online monitoring

Autor: Moore Karabo, Louw Danie, Kouprianoff Dean

Publikováno v: MATEC Web of Conferences, Vol 370, p 01004 (2022)

In laser powder bed fusion factors such as residual stresses within the part, lead to deformations and cracks which impact the quality of the final product. Although residual stress and deformations have been thoroughly studied research and developme

Effect of design and tensile testing specimen geometry on final tensile properties of powder bed fusion plastic

Autor: Kouprianoff Dean, Moore Karabo

Publikováno v: MATEC Web of Conferences, Vol 370, p 08005 (2022)

In Laser Powder Bed Fusion there are certain considerations that need to be accounted for when designing for thin-walled or complex shapes. Much is known of how parameters such as build orientation and scanning strategy can affect the resultant tensi
