Poly‐Ether‐Ether‐Ketone Melt Behavior in Fused Deposit Modeling Printing Moves
Polymer Engineering &Science, EarlyView.A thin solidified layer forms at the print bed during FDM of PEEK, reducing the effective shear height and raising the effective shear rate above the nominal value. Surface defects emerge once the effective shear rate exceeds a critical value of approximately 750 s−1.
