Adaptive slicing for AFSD based on spatial hashing and projected area deviation

Journal of Physics: Conference Series
Abstract This paper presents a topology reconstruction and adaptive slicing method for additive friction stir deposition (AFSD). A spatial hashing-based approach is used to efficiently reconstruct STL topology, reducing data redundancy and improving preprocessing efficiency. An adaptive slicing method based on projected area deviation

Stability of Al3(Sc,Zr) Dispersoids During AFSD of AlMg-Sc-Zr Alloys and Impact on Microstructure and Corrosion Resistance

Materials Science and Engineering: A
Additive Friction Stir Deposition (AFSD) technology is gaining attention for its ability to produce large aluminium alloy components without melting. To ensure alignment with the goal of reducing energy consumption, and considering the difficulty of performing post-heat treatment for such large-scale components, post-process treatment should be avoided.
