Abstract
Producing consistent and homogeneous packing structure in powder layer deposition for cohesive raw materials under varying thermal conditions is challenging for additive manufacturing. Interparticle cohesion and thermal parameters play key roles on the structure of powder layer deposited on the substrate in additive manufacturing. In this work, we characterize the structural anisotropy of the deposited powder layer and quantify the packing structure on the particle-level using a threshold-free local packing anisotropy based on Voronoi tessellation. Based on the statistics of the local anisotropy, we observe a transition in the structure of the deposited powder layer from homogeneous to heterogeneous for cohesive materials at Bo=10. Including an idealized temperature-dependence of the normal contact force does not influence the structure of the deposited layer in powder spreading.
