Balling processes during selective laser treatment of powders

Nikolay K. Tolochko, Sergei E. Mozzharov, Igor A. Yadroitsev, Tahar Laoui, Ludo Froyen, Victor I. Titov, Michail B. Ignatiev

The particularities of the selective laser processing of single‐component metal powder layers were investigated, especially the occurrence of the balling‐processes under different…

Selective laser sintering and cladding of single‐component metal powders

Nikolay K. Tolochko, Sergei E. Mozzharov, Igor A. Yadroitsev, Tahar Laoui, Ludo Froyen, Victor I. Titov, Michail B. Ignatiev

A comparison of selective laser sintering (SLS) and selective laser cladding (SLC) methods is presented. Loose single‐component, Ni‐alloy powder was used in this study. The powder…

A topological hierarchy‐sorting algorithm for layered manufacturing

S.H. Choi, K.T. Kwok

This paper proposes an algorithm that constructs the topological hierarchy relationship of complex slice contours for layered manufacturing (LM). It facilitates toolpath…

Manufacturable surface reconstruction from complex contours

Weishi Li, Shuhong Xu, Gang Zhao

To retrieve the geometric information contained in CT images, a surface reconstruction method, which is based on the similarity between the corresponding contours of adjacent…

Benchmarking for comparative evaluation of RP systems and processes

M. Mahesh, Y.S. Wong, J.Y.H. Fuh, H.T. Loh

A geometric benchmark part is proposed, designed and fabricated for the performance evaluation of rapid prototyping machines/processes. The benchmark part incorporates key shapes…

Rapid prototyping fabricated by UV resin spray nozzles

C.C. Chang

Rapid prototyping (RP) processes produce parts layer by layer directly from 3D CAD models. Different kinds of rapid prototyping machine (RPM) have been developed with different…

Three‐dimensional plotting as a visualisation aid for architectural use

Deon J. de Beer, Ludrick J. Barnard, Gerrie J. Booysen

Functional design is closely linked to manufacturing and building. Designers' freedom to express themselves is often limited by the capabilities of craftsmen who have to give…
