“…The use of a nozzle with a large hole diameter accelerates the part production time [ 98 ]. It has also been reported that increasing the nozzle diameter increases the part quality and mechanical properties in FDM 3D printing [ 99 ]. The other important parameter is the ambient temperature which causes part warpage.…”

“…Nozzle temperature is the temperature at which the material is melted and extruded from the nozzle. It has a high influence on the mechanical properties and microstructure of the 3D printed parts [ 99 ]. For instance, the increase in relative density (from 89.9% to 92.8% for PEEK) with the increase in nozzle temperature from 370 °C to 390 °C is reported [ 103 ].…”

Additive manufacturing (AM) or 3D printing is a digital manufacturing process and offers virtually limitless opportunities to develop structures/objects by tailoring material composition, processing conditions, and geometry technically at every point in an object. In this review, we present three different early adopted, however, widely used, polymer-based 3D printing processes; fused deposition modelling (FDM), selective laser sintering (SLS), and stereolithography (SLA) to create polymeric parts. The main aim of this review is to offer a comparative overview by correlating polymer material-process-properties for three different 3D printing techniques. Moreover, the advanced material-process requirements towards 4D printing via these print methods taking an example of magneto-active polymers is covered. Overall, this review highlights different aspects of these printing methods and serves as a guide to select a suitable print material and 3D print technique for the targeted polymeric material-based applications and also discusses the implementation practices towards 4D printing of polymer-based systems with a current state-of-the-art approach.

“…This was explained, by the authors, by the gravitational force that helps to spread the melted plastic and it is more efficient for large nozzle diameters. Triyono et al (2020) [79] investigated the effect of nozzle diameter on the ultimate tensile stress (UTS) of 3D-printed PLA parts. The nozzle diameters used in this study varied from 0.3 to 0.6 mm.…”

Additive Manufacturing is currently growing fast, especially fused deposition modeling (FDM), also known as fused filament fabrication (FFF). When manufacturing parts use FDM, there are two key parameters—strength of the part and dimensional accuracy—that need to be considered. Although FDM is a popular technology for fabricating prototypes with complex geometry and other part product with reduced cycle time, it is also limited by several drawbacks including inadequate mechanical properties and reduced dimensional accuracy. It is evident that part qualities are greatly influenced by the various process parameters, therefore an extensive review of the effects of the following process parameters was carried out: infill density, infill patterns, extrusion temperature, layer thickness, nozzle diameter, raster angle and build orientation on the mechanical properties. It was found from the literature that layer thickness is the most important factor among the studied ones. Although manipulation of process parameters makes significant differences in the quality and mechanical properties of the printed part, the ideal combination of parameters is challenging to achieve. Hence, this study also includes the influence of pre-processing of the printed part to improve the part strength and new research trends such as, vacuum-assisted FDM that has shown to improve the quality of the printing due to improved bonding between the layers. Advances in materials and technologies that are currently under development are presented. For example, the pre-deposition heating method, using an IR lamp of other technologies, shows a positive impact on the mechanical properties of the printed parts.

“…Penelitian terhadap filamen PLA dengan pengaturan bed temperature 60°C, nozzle temperature 200°C, dan printing speed 80 mm/s. Type infill bentukl line dengan densitas 100% menunjukkan bahwa semakin besar nozzle yang digunakan memberikan pengaruh terhadap kuat tarik, tetapi tidak meningkat signifikan atau tidak meningkat secara linear [14]. Tujuh variasi diameter nozzle, 0,2mm, 0,3mm, 0,4mm, 0,5mm, 0,6mm 0,8mm, dan 1mm telah digunakan untuk mencetak spesimen uji tarik standar PN-EN ISO 527:1998 menunjukkan bahwa diameter nozzle 0,5mm menghasilkan kuat tarik tertinggi yaitu 1,93 kN [15].…”

Pengaturan parameter proses 3D Printing berteknologi Fused Deposition Modelling (FDM) sangat mempengaruhi kualitas produk cetak baik dalam hal akurasi dimensi, surface roughness, dan kekuatan tariknya. Dua material yang paling sering digunakan para praktisi 3D Printing adalah PLA dan ABS masih memerlukan pengaturan parameter proses pada slicing software untuk menghasilkan produk cetak paling kuat ditinjau dari kuat tariknya. Penelitian ini memvariasikan bentuk geometri infill yang tersedia pada Ultimaker Cura 4.8.0 dalam mencetak spesimen uji tarik ASTM D638 Type IV. Ada 13 (tiga belas) bentuk infill yang digunakan dengan infill density 100%. Ada 3 (tiga) variasi nozzle temperature yaitu 205°C, 215°C, dan 225°C. Parameter proses yang tetap seperti layer thickness 0,2 mm, printing speed 50 mm/s, travel speed 100 mm/s, dan bed temperature 60°C. Spesimen uji tarik dicetak masing-masing tiga buah pada 39 (tiga puluh sembilan) eksperimen dan rata-rata hasil uji tarik dihitung kemudian selanjutnya dianalisis. Nilai kekuatan tarik tertinggi diperoleh pada pengaturan nozzle temperature 205°C dengan bentuk infill concentric atau terdapat pada eksperimen nomor 9 dengan nilai 32,40 MPa. Sedangkan nilai kekuatan tarik diperoleh pada pengaturan nozzle temperature 225°C dan dengan bentuk infill cross atau pada eksperimen nomor 37 dengan nilai 19,10 MPa. Sehingga dapat disimpulkan bahwa bentuk geometri infill pada proses 3D Printing FDM sangat mempengaruhi kekuatan tarik produk cetak.
