Facilitating the additive manufacture of high-performance polymers through polymer blending: A review

European Polymer Journal, Journal Year: 2023, Volume and Issue: 201, P. 112553 - 112553

Published: Nov. 7, 2023

Fused Filament Fabrication (FFF, a.k.a. fused deposition modeling, FDM) is presently the most widespread material extrusion (MEX) additive manufacturing technique owing to its flexibility and robustness. Nonetheless, it remains underutilized in load-bearing applications, as often seen aerospace, automotive biomedical industries. This largely due processing challenges associated with high performance polymers (HPPs) like poly-ether-ether-ketone (PEEK) or polyetherimide (PEI). Compared commercial-grade plastics such polylactic acid (PLA), parts produced HPPs have outstanding mechanical properties thermal stability. However, bulkier chemical structures stronger intermolecular forces than common FFF feedstock materials, this results much higher printing temperatures greater melt viscosities. The demanding requirements of thus impaired their adoption within FFF. Polymer blending, which consists properly mixing other thermoplastics, makes possible alleviate these issues, while also providing additional advantages improved tensile strength reduced friction. Further this, manipulating crystallisation processes mitigates distortion warping upon printing. review explores some emerging trends field HPP blends how they address excessive viscosity, polymer crystallization, moisture uptake, part shrinkage 3D Also, various structural/mechanical/chemical enhancements that are afforded through blending critically analysed based on recent examples from literature. Such insights will not only aid researchers field, but facilitate development novel, printable blends.
