Additive Manufacturing (AM) is a process of joining materials to make objects from 3D model data, usually layer upon layer. There are barriers and challenges bordering the development of AM. First, there are many complex multi-physics phenomena during most AM processes, such as molten pool dynamic problem and spatter problem. Second, the comprehensive interaction effect among factors like materials, the support of component, heat transfer and operation parameters, result in manufacturing defects. Third, the freeform design based on AM usually is applied in multi-phase or strict conditions that are difficult to measure or analyze. The newly CAD design methods and numerical simulation, as well as other computational approaches are key to solve these problems and push the development of AM.

With the rapid growth of researches in additive manufacturing, we initiate this special issue to highlight the recent developments with simulation and computational approaches in AM. This special issue seeks original manuscripts to investigate the theory, design, optimization, simulation and process of AM. Papers which deal with multi-physics problems, as well as those which deal with the interfaces of mechanics, chemistry, and biology, are particularly encouraged. Various length scales (quantum, nano, micro, meso, and macro), and various time scales (femtoseconds to hours) are of interest. Both experimental and modeling submissions are encouraged.
Potential topics included but are not limited to: 
(1) Design, modeling, simulation and analysis based on AM.
(2) Simulation of microstructure stability and evolution during or after the AM process.
(3) Simulation of multi-physics problems in AM, such as molten pool dynamic problem, spatter problem, ejection and injection problems.

  • Novel Micromixer with Complex 3D-Shape Inner Units: Design, Simulation and Additive Manufacturing
  • Abstract In this paper, a novel micromixer with complex 3D-shape inner units was put forward and fabricated by metal Additive Manufacturing (AM). The design of the micromixer combined the constraints of selective laser melting technology and the factors to improve mixing efficiency. Villermaux-Dushman reaction system and Compute Fluid Design (CFD) simulation were conducted to investigate the performance and the mechanism of this novel micromixer to improve mixing efficiency. The research found that the best mixing efficiency of this novel micromixer could be gained when the inner units divided fluid into five pieces with a uniform volume. Compared with a conventional micromixer… More
