Optimal-transport-based geometry modeling for material extrusion additive manufacturing

S. Chen, S. Liu, S. He, M. Duan

Overview

An optimal-transport model describes how a moving nozzle reshapes extruded material. Two- and three-dimensional formulations predict line and corner profiles while considering viscous resistance, gravity, and changes in surface geometry.
