A visco-elastic contact model is developed using normal impact experiments and then confirmed with oblique impact experiments. The force coefficients are determined using a genetic algorithm. The impact on the polylactic acid surface is defined by a coefficient of restitution, coefficient of friction, and the coefficients of the contact force. The simulations demonstrate good compatibility with the experimental data.eninfo:eu-repo/semantics/openAccessimpact3D printingimage processingArticle2315WOS:001633991600001
