“…Chain extenders under the trade name Joncryl have been successfully used to improve the compatibility of polymer blends with PLA, such as PLLA/PDLA or poly(butylene adipate-co-terephthalate)/poly(lactide) (PBAT/PLA), resulting in better mechanical and thermal properties [18][19][20][21][22]. Epoxide chain extenders have also been able to improve the layer-to-layer adhesion strength of 3D-printed PLA layers [23] and impart printability in some polymer blends (PLA/polyamide 11) [7,24], PBAT/PLA [25,26], as well as PLA-based composites [27].…”

Fused deposition modeling (FDM) is currently the most popular 3D printing method, where thermoplastic polymers are predominantly used. Among them, the biobased poly(lactic acid) (PLA) governs the FDM filament market, with demand higher than supply, since not all grades of PLA are suitable for FDM filament production. In this work, the effect of a food grade chain extender (Joncryl ADR® 4400) on the physicochemical properties and printability of PLA marketed for injection molding was examined. All samples were characterized in terms of their mechanical and thermal properties. The microstructure of the filaments and 3D-printed fractured surfaces following tensile testing were examined with optical and scanning electron microscopy, respectively. Molecular weight and complex viscosity increased, while the melt flow index decreased after the incorporation of Joncryl, which resulted in filaments of improved quality and 3D-printed constructs with enhanced mechanical properties. Dielectric spectroscopy revealed that the bulk properties of PLA with respect to molecular mobility, both local and segmental, were, interestingly, not affected by the modifier. Indirectly, this may suggest that the major effects of the extender are on chain length, without inducing chain branching, at least not to a significant extent.

“…Most of the materials used for the FFF process are not environmentally friendly. Bioplastics and their composites filaments are less expensive than fossil-based plastic filaments [122]. However, the importance of developing filaments from biobased and biodegradable bioplastics and their composites is yet to get significant attention from researchers.…”

Fused filament fabrication (FFF) is one of the most popular additive manufacturing (AM) processes that utilize thermoplastic polymers to produce three-dimensional (3D) geometry products. The FFF filament materials have a significant role in determining the properties of the final part produced, such as mechanical properties, thermal conductivity, and electrical conductivity. This article intensively reviews the state-of-the-art materials for FFF filaments. To date, there are many different types of FFF filament materials that have been developed. The filament materials range from pure thermoplastics to composites, bioplastics, and composites of bioplastics. Different types of reinforcements such as particles, fibers, and nanoparticles are incorporated into the composite filaments to improve the FFF build part properties. The performance, limitations, and opportunities of a specific type of FFF filament will be discussed. Additionally, the challenges and requirements for filament production from different materials will be evaluated. In addition, to provide a concise review of fundamental knowledge about the FFF filament, this article will also highlight potential research directions to stimulate future filament development. Finally, the importance and scopes of using bioplastics and their composites for developing eco-friendly filaments will be introduced.

“…Current 3D printing technologies allow the precise deposition of biocompatible materials, while at the same time potentially providing mechanical properties for optimal compliance match to the recipient surrounding tissue. Today, a wide range of 3D printable biomaterials is available, such as cell-laden hydrogel bioinks [84], which provide proper cell environment but still lack sufficient mechanical scaffolding properties, or biocomposite scaffold materials that can be produced through fused deposition modeling [85]. 3D printing can be used also for improving medical imaging technologies [86] and for producing anthropomorphic phantoms with realistic radiation attenuation properties [87].…”
