The viscous sintering kinetics of thermoplastic polymers is generally studied by monitoring the evolution bonding neck between two particles (spherical, or cylindrical) and using a refined Frenkel-Eshelby’s model. Recently, we showed that entire contour filaments could be modelled lemniscates as figure-eight shape curves to assess abilities 3D-printable plasticized biopolymer. Using COMSOL Mult...
