• MeltpoolNet: Melt pool characteristic prediction in Metal Additive Manufacturing using machine learning

  Additive manufacturing · 2022-04-28 · 138 citations

  articleOpen access

  Characterizing melt pool shape and geometry is essential in Metal Additive Manufacturing (MAM) to control the printing process, and avoid defects. Predicting melt pool flaws based on process parameters and powder material is difficult due to the complex nature of MAM processes. Machine learning (ML) techniques can be useful in connecting process parameters to the type of flaws in the melt pool. In this work, we introduced a comprehensive framework for benchmarking ML for melt pool characterizati…

• Preparation of PLZT Powder by a Citrate Gel Technique

  2024-10-15 · 3 citations

  book-chapterSenior author

  Homogeneous PLZT ceramic powder can be prepared from citrate source solution using a gelation process which avoids alcohol dehydration involving large volumes of expensive ethanol. Cl− is a critical impurity in the gel evaporating during calcination as PbC12, rendering the powder PbO deficient and halting formation of PLZT. However, removal of the Cl− enables single-phase PLZT to be formed at temperatures as low as 375°C, crystallisation being caused by the oxidation of carbon arising from the c…
