The emergence of Additive Manufacturing (AM) has created a plethora of opportunities for different industries due to its application in 3D printing technology. Since its introduction back in 1980, 3D printing technology has overseen numerous developments and changes. A rarity back in the day, 3D printing has now become cheaper and available for everyone who wishes to learn and experiment with the technology. Although 3D printing technology can produce optimized and detailed printing at a cheaper rate than in earlier days, it can still be time-consuming and quite costly due to the technology's tendency to follow the trial-and-error method when printing. A proposed solution to such an issue is by implementing Digital Twin (DT), a virtual representation of an object that provides real-time reflection between the virtual and physical space and can interact and converge with the flow of data between both spaces. However, despite the need, Digital Twin is yet to achieve its fullest potential due to a gap in knowledge regarding its concept and development methods. This paper, therefore, intends to provide a brief review regarding the implementation, applications as well as challenges of DT for 3D printing, to provide an understanding of the current trends that can be utilized for further research regarding Digital Twin and its implementation in 3D printing.

“…Numerous studies have been conducted to explore the implementation of digital twin for fused deposition modeling (FDM) field, with a particular emphasis of defect monitoring and analyzing anomalies in the FDM production process [12], [13], [14]. These anomalies cover various aspects including surface defects, cracks, failure cases and production of substandard products.…”

Digital twin (DT) is a modern concept that allows for the creation of the digital model of the manufacturing process, and hence for the product life-cycle monitoring. DT could provide manufacturing details and identify potential shifts and anomalies during printing. It has a significant potential in additive manufacturing as an avenue to address manufacturing uncertainties. In this study, the digital twin for the fused deposition modeling method of the additive manufacturing was developed. DT provides information about the speed of sound within the material. Information about the sound speed is used to evaluate the elastic properties of printed material. The results of sound speed measurements in the PLA samples printed using various combinations of parameters of the printing process are analyzed. Using the measurements results, the response surface linking the elastic properties of the material to the parameters of the printing process is established. Based on the information about speed of sound within the material, further actions could be taken on the adjustment of the printing process in order to obtain desirable properties. An analytical model of the sound speed propagation within the material was developed and evaluated using the experimental data. It is suggested that DT combined with the printing response surface is a valuable approach to control of the printing process. This integrated approach demonstrates considerable promise in steering additive manufacturing towards the attainment of specified material properties.

“…The growing use of 3D printing and the need to design functional parts for final use in the industry has generated the need to develop Design For Additive Manufacturing (DFAM) guidelines that, together with the support of analytical tools, try to predict and improve the mechanical behavior of parts obtained by 3D printing [4]. Thus, the need to investigate the influence of the various printing parameters on the mechanical properties is justified, namely the infill, as this is one of the parameters with a direct influence on the printing time and amount of material consumed in 3D printing [5,6,7].…”

Fused Filament Fabrication (FFF) is a growing additive manufacturing technology for various applications in the engineering field. The mechanical properties of 3D printed materials in FFF technology depends on various parameters and the literature suggests that infill pattern and infill density are the parameters that most affect the mechanical properties of 3D printed parts.These factors have direct influence on the time of production and amount of material used. In this work it was analyzed the influence of infill parameter on stiffness of the final parts, considering the printing time and amount material used. For this purpose, the Taguchi method was used and then the statistical method of ANOVA to calculate the influence of each parameter.Test specimens were printed according to ASTM Standard D790 dimensions, in Polyethylene terephthalate glycol (PETG). The specimens were printed in the same position on the printing bed to reduce as much as possible the influence of external factors on the results. A visual and dimensional inspection of the specimens was carried out for further analysis. The best combination between production and stiffness, with 350 MPa/mm, was obtained with 15% infill density, concentric pattern, 45º orientation, with 4 perimeters path, layer thickness of 0.1 mm and speed of 45 mm/s. The results obtained allow us a broader view of how to save 3D printing time and the amount of material consumed during the production of a part.
