Current practice-oriented understanding of how a material destined for 3D printing processing interacts with printers is inadequate. The thermo-mechanical processes which materials must endure during 3D printing processing are very influential. For high temperature thermoplastics and reinforced polymer matrix materials it can be a technical challenge to bring printed parts to fully conform to design tolerances. This presentation will focus on the development of a printing process control tool for high temperature polymers. The role of temperature, printing speed and fundamental material properties will be highlighted.
