Short fiber reinforcement in material extrusion 3D printing: A meta‐analysis review with insights into sustainable alternatives

Polymer Composites, Journal Year: 2025, Volume and Issue: unknown

Published: April 4, 2025

Abstract Short fiber reinforcement is a key for improving the mechanical properties of thermoplastic composites produced by 3D printing. However, strengthening potential fibers often under‐utilized due to sub‐optimal processing conditions. This meta‐analysis review systematically evaluates microstructural and short fiber‐reinforced composites, identifying trends related fragmentation, fiber‐matrix interactions, property optimization. Our statistical analysis results show that content initial length have minimal effect on average remaining in filament, which highlights conditions are primary control breakage. In addition, aspect ratio does not direct correlation with tensile strength, can be insufficient adhesion. Despite these drawbacks, still increase modulus an 2.22 times flexural 2.69 times. Analytical models predicting also presented, noting while they provide valuable insights, time‐consuming experimental validation required accurate estimates. Finally, we insights into sustainable waste‐derived fillers as alternatives conventional fibers. Although their performance remains less predictable, surface treatment strategies advanced multi‐scale modeling techniques will essential establish structure–property relationships exploit fully. Ultimately, hold significant promise replacing raw material from sources, paving way more composite Highlights Waste‐derived emerging 3D‐printed composites. Improved micromechanical needed predict effects waste fillers. Statistical shows strength independent ratio. Filler affect fragmentation during filament manufacturing.

Experimental Investigations of the Influence of Spent Coffee Grounds Content on PLA Based Composite for 3D Printing

Journal of Research Updates in Polymer Science, Journal Year: 2024, Volume and Issue: 13, P. 226 - 233

Published: Nov. 8, 2024

Nowadays Fused Deposition Modeling, a widely utilized additive manufacturing technology, is significantly transforming as modern production processes. Beyond basic uses to it role in sustainability, Modeling offers processing potential for implanting circular economy by reducing virgin materials consumption and enhance the integration of waste food sustainable 3D printing. This research paper investigated new composite based on spent coffee grounds. In addition, PLA SCG at various contents (0, 3, 5, 10, 15 wt%) were dried premixed, then processed into PLA/SCG pellets using twin-screw extrusion. These successfully converted filaments subsequently used The effect grounds composites was via physical mechanical analysis printed samples. Regarding density measurements, results revealed that adding up 5 wt% increased while further additions led decrease which due printing parameters such extrusion temperature nozzle diameter. Considering properties, Young’s modulus once content reached 3 decreased. other hand, there no enhancement tensile strength elongation break corroborating with measurements. mainly contributed changes properties caused parameters. study demonstrates can be filler environmentally friendly printing, maximum wt%. approach not only promotes reuse but also reduces cost traditional filaments.
