Rapid tooling using additive manufacturing, or 3D printing, is an emerging manufacturing technology that has the potential to revolutionize the production of complex parts using only a computer and a design program. Lightweight structures with excellent dimensional precision and lower cost for customizable geometries are possible with these printed parts. In recent years, inherent constraints of polymers, metals, and ceramics have pushed researchers toward superior alternative composite materials to boost mechanical and other critical features; current 3D printing research follows this route from neat to composite materials. The characteristics, performance, and future uses of composite materials produced using additive manufacturing methods are discussed in this review. In addition, to discuss the state of the art in additive manufacturing, this article also fabricated many technologies, including robotics, machine learning, organ-on-a-chip, and 4D bioprinting.

Additive manufacturing technique fused filament fabrication (FFF) has found widespread usage in a variety of sectors, because of its ability to produce parts with arbitrary geometries and intricate internal structures. This study focuses on the characterization of polylactic acid (PLA) and polyethylene terephthalate glycol (PETG) composites under compressive force to learn more about how various nozzle diameter (ND) and infill pattern (IP) affect the fabricated specimens. The specimens are created with various combination of IPs (triangular, honeycomb, and rectilinear) and NDs (0.2, 0.4, and 0.6 mm) utilizing three polymer composites namely carbon fiber filled PLA (CF-PLA), carbon fiber filled PETG (CF-PETG), and multi walled carbon nano tubes filled PLA (MWCNTs-PLA). According to the findings, the higher ND improves the compressive properties of the polymer composites. The IP also has significant impact on the compressive properties of the fabricated specimens. The overall minimum compressive strength of 14.612 MPa at ND 0.2 mm and honeycomb IP for CF-PLA specimen. The overall maximum compressive strength achieved is 45.269 MPa at ND 0.6 mm and rectilinear IP for MWCNTs-PLA specimen.Therefore, the compressive strength is enhanced by 209.81% by modifying the process parameters and filament material. Based on statistical analysis using Taguchi method, the ND contributes highest, 79.61% to compressive strength of MWCNTs-PLA specimens, but for CF-PLA and CF-PETG specimens, IP contributes highest, 52.65% and 57.91%, respectively. The aforementioned findings will be extremely useful to scientists attempting to achieve sustainability through the use of polymer composites and FFF process.compressive behavior, fused filament fabrication, infill pattern, nozzle diameter, polymer composites | INTRODUCTIONAdditive manufacturing (AM) has evolved from a prototyping technique to one employed in the manufacture of finished, consumer-ready goods.

Fused filament fabrication (FFF) is one of the most common 3D printing techniques having considerable potential in various fields such as pharmaceutical, medical, aerospace, and automotive. One of the impediments of FFF components is their lower mechanical performance compared with those from conventional fabrication methods. This work aims to investigate the effect of adding nanoclay due to being nontoxic to the biodegradable polylactic acid (PLA) polymer matrix for medical applications. PLA granules were melt-compounded by a twin-screw extruder with nanoclay at 2 and 4 wt.%, and then, PLA and PLA/nanoclay filaments were produced using a single-screw extruder. An L9 orthogonal array of the Taguchi approach was utilized as the design of the experiment tool to study the process in detail considering nanoclay content, nozzle temperature and raster angle as material and processing parameters. The dispersion of nanoclay in the PLA matrix was assessed by X-ray diffraction test. The results indicated that the tensile strength was enhanced by 4.6% and 15.3% using the addition of 2 and 4 wt.% of nanoclay, respectively. The microscopic observations showed that the bonding between the rasters and between the contours and rasters was improved by increasing the temperature, and consequently, led to higher tensile strength values. The results revealed that the tensile strength of 38.9 MPa was obtained at the optimum condition.
