“…Copper and lignin are used as fillers for impact resistance enhancements. The addition of lignin microspheres resulted in an increase in impact strength of 100% [69], and Cu-modified PLA achieved remarkable results in impact resistance tests as well [70]. Regarding the change in processing parameters, Fontana et al analyzed the effects of layer height (LH) and fill rate on the ultimate tensile strength (UTS) values of 3D-printed tensile specimens of Makerbot PLA rigid materials [71,72].…”

The proliferation of polymer science and technology in recent decades has been remarkable, with synthetic polymers derived predominantly from petroleum-based sources dominating the market. However, concerns about their environmental impacts and the finite nature of fossil resources have sparked interest in sustainable alternatives. Bio-based polymers, derived from renewable sources such as plants and microbes, offer promise in addressing these challenges. This review provides an overview of bio-based polymers, discussing their production methods, properties, and potential applications. Specifically, it explores prominent examples including polylactic acid (PLA), polyhydroxyalkanoates (PHAs), and polyhydroxy polyamides (PHPAs). Despite their current limited market share, the growing awareness of environmental issues and advancements in technology are driving increased demand for bio-based polymers, positioning them as essential components in the transition towards a more sustainable future.

“…In one of these investigations, Pavan et al [23] conducted an analysis of the impact and shear behavior of PLA/12% copper (Cu) composite samples reinforced by the FFF method. The researchers used experiments based on Taguchi's L 9 orthogonal array to determine how printing conditions, including nozzle temperature, bed temperature, and layer height, influenced the composite samples.…”

The benefits of the fused filament fabrication (FFF) method, including its simplicity, affordability, and accessibility, have made it the most commonly used additive manufacturing technique. Polylactic acid (PLA) is the most widely used material in FFF, but its use has been limited by low mechanical properties and a small processing window. To address this, PLA composites are used to improve its properties. Correlating mechanical properties with process parameters is crucial for producing high-quality composite parts. This study investigated the effects of material and process parameters on mechanical properties, such as tensile strength and elongation-at-break, using a customized Delta Rostock FFF printer. Two types of filaments were used, pure PLA and PLA/Aluminum composites. Printing speed (10, 20, and 30 mm/s) and raster angle (0/90, −45/45, and −30/60) were selected as process input parameters. The Taguchi method was used for the experiment design, and signal-to-noise ratio analysis was used for statistical optimization. The optimal values for achieving maximum tensile strength of 61.85 MPa and maximum elongation-at-break of 17.7% were determined. Furthermore, the signal-to-noise ratio analysis indicated that the filament type had the greatest influence on the tensile strength, whereas printing speed had the greatest impact on the elongation-at-break.

“…It is reported that 25 wt.% Cu addition showed superior mechanical resistance compared to 80 wt.% reinforcement in terms of tensile, compressive, and flexural strengths. Venkata Pavan et al 31 blended 20-30 μm copper particulates with PLA powder in ratios of 4, 8, 12, 16, and 20 wt.% and investigated the effect of process parameters on impact and shear behavior in terms of following parameters: 190-230°C extruder temperature, 50-70°C bed temperature with 100% infill percentage for 12 wt.% Cu-filled PLA parts. It is mentioned that adding filler material more than 20% is hard to extrude composite filament continuously.…”

In the study, parts are fused deposition modeling–printed using polylactic acid filaments filled with copper, brass, bronze, tungsten, and carbon fiber. Wear and three-point bending tests are applied to FDM-printed specimens and it is yielded that on-edge oriented specimens had higher flexural strength while flat orientation contributed to wear resistance. Wear tracks are examined, and mostly abrasive wear is detected in the dry sliding condition while adhesive, fatigue and abrasive wear is observed in the wet sliding condition. Brass-filled polylactic acid specimens showed highest flexural strength and flexural modulus with 46.73 MPa and 1.53 GPa, respectively. Besides, the most wear resistant filler is determined as tungsten for dry and wet sliding conditions.
