Fused filament fabrication (FFF) has been extensively studied for conventional polymers, but there are few studies that address the processing challenges biobased, biodegradable polymers such as poly(lactic acid) (PLA) and poly(hydroxy alkenoates) (PHA) in FFF processes. This study investigated elongational shear rheological properties thermophysical characteristics of PLA/PHA hybrid materials to determine effects conditions, including nozzle temperatures, bed speeds, on quality printed products, e.g., adhesion strength tensile properties. Our findings showed adding PHA composition material leads a reduction extensional viscosities, causing rise elongation at break while showing comparable with PLA samples. In addition presence combination materials, temperature, print speed, were found be effective products. results suggested among parameters, temperature most significant effect characteristics.

Recycling as a Key Enabler for Sustainable Additive Manufacturing of Polymer Composites: A Critical Perspective on Fused Filament Fabrication

Polymers, Год журнала: 2023, Номер 15(21), С. 4219 - 4219

Additive manufacturing (AM, aka 3D printing) is generally acknowledged as a “green” technology. However, its wider uptake in industry largely relies on the development of composite feedstock for imparting superior mechanical properties and bespoke functionality. Composite materials are especially needed polymer AM, given otherwise poor performance most parts load-bearing applications. As drawback, shift from mono-material to may worsen environmental footprint AM. This perspective aims discuss this chasm between advantage embedding advanced functionality, disadvantage causing harm environment. Fused filament fabrication (FFF, fused deposition modelling, FDM) analysed here case study account unparalleled popularity. FFF, which belongs material extrusion (MEX) family, presently widespread AM technique industrial, educational, recreational On one hand, FFF has already transitioned “from lab fab” finally community, with far-reaching implications sustainability. other thermoplastic-based, hence highly amenable recycling. The literature shows that recycled thermoplastic such poly(lactic acid) (PLA), acrylonitrile-butadiene-styrene (ABS), polyethylene terephthalate (PET, or glycol-modified form PETG) can be used printing by printed objects when they at end life. Reinforcements/fillers also obtained materials, help valorise waste by-products wide range industries (for example, paper, food, furniture) agriculture.
