“…−45°/+45° printing direction showed good tensile value. Sekar et al [ 162 ] investigated the acoustic performance of PLA/wood composite panels by varying sample thickness (1.35, 3, 4 and 5) and filled density (20, 40, 60, 80 and 100). The results indicated that a sample with 5 mm thick and 100 fill density aborded higher sound frequency.…”

“…After the surface treatment, the fiber surface becomes hard, firmly sticks to the matrix, and avoids pull-out. [162] The purpose of pretreatment was to remove hemicellulose, lignin, pectin, and wax from the fiber, but using lignin as filler material enhanced the mechanical performance. [87,88] The Scanning Electron Microscope revealed that pre-treated composites showed homogenous dispersion, [89,151] and fiber pullouts were much less.…”

A comprehensive review on natural fillers reinforced polymer composites using fused deposition modeling

Additive manufacturing (AM) is being used more widely because of the simplicity of the operating procedures. It decreases material consumption during part production and eliminates material waste. Fused deposition modeling (FDM), a well‐known AM process, uses thermoplastic polymer as a feedstock to manufacture the end design. Pure thermoplastic‐based products are still utilized as prototypes in several sectors due to their lack of strength and durability. This problem has been solved by strengthening the thermoplastics by adding a reinforcing element. Composites are made of polymers and various constituents known as reinforcing components. This article overviews natural reinforced polymer composites used in the FDM process. Mechanical and Thermal properties are presented based on natural filler percentage, and this article only considered natural composite filaments for the FDM process.

“…Strain energy absorption rates increased as infill density increased (Vigneshwaran and Venkateshwaran, 2019). The acoustic performance of an additively manufactured natural fibrereinforced composite was investigated, and it was discovered that when infill density was reduced to 60%, sound absorption capacity increased (Sekar et al, 2021a(Sekar et al, , 2021b.…”

Purpose This paper aims to investigate the current state of biocomposites used in fused deposition modelling (FDM) with a focus on their mechanical characteristics. Design/methodology/approach The study presents a variety of biocomposite materials that have been used in filaments for 3D printing by different researchers. The process of making filaments is then described, followed by a discussion of the process parameters associated with the FDM. Findings To achieve better mechanical properties of 3D-printed parts, it is essential to optimize the process parameters of FDM while considering the characteristics of the biocomposite material. Polylactic acid is considered the most promising matrix material due to its biodegradability and lower cost. Moreover, the use of natural fibres like hemp, flax and sugarcane bagasse as reinforcement to the polymer in FDM filaments improves the mechanical performance of printed parts. Originality/value The paper discusses the influence of critical process parameters of FDM like raster angle, layer thickness, infill density, infill pattern and extruder temperature on the mechanical properties of 3D-printed biocomposite.

In recent times, Additive Manufacturing (AM) has been applied rapidly in almost all fields. This study was conducted to apply the additive manufacturing into an acoustic application by 3D printing the Micro-Perforated Panels (MPP) through Fused Deposition Modelling (FDM) made of Polylactic Acid (PLA) reinforced with wood fibers. MPP were fabricated by altering its perforation volume. Later, the effect of perforation volume on acoustic absorption of the fabricated MPP was measured using the two-microphone impedance tube method as per ISO 10534-2 standard. The result shows altering the perforation volume affects the acoustic absorption of the MPP. MPP with a thickness of 2 mm and a perforation diameter of 0.2 mm shows the maximum sound absorption coefficient of 0.93 at 2173 Hz. It is made possible to absorb the 3D printed MPP made of natural fiber reinforced composite at different spectrums by altering the perforation volume.
