“…Printing parameters included a layer height of 0.2 mm, external perimeter thickness of 0.5 mm and top/bottom thickness of 0.8 mm, as per the default fast draft setting in Cura. Polylactic acid (PLA) was chosen as the printing material due to its reduced particle emission and ease of use . A duplicate was made for each 3D printed shell to check for printing reproducibility and conformity of fit, with the internal fill density varied from 100% to 18% to reduce print time (Fig.…”

Introduction Three‐dimensional printing technology has the potential to streamline custom bolus production in radiotherapy. This study evaluates the volumetric, dosimetric and cost differences between traditional wax and 3D printed versions of nose bolus. Method Nose plaster impressions from 24 volunteers were CT scanned and planned. Planned virtual bolus was manufactured in wax and created in 3D print (100% and 18% shell infill density) for comparison. To compare volume variations and dosimetry, each constructed bolus was CT scanned and a plan replicating the reference plan fields generated. Bolus manufacture time and material costs were analysed. Results Mean volume differences between the virtual bolus (VB) and wax, and the VB and 18% and 100% 3D shells were −3.05 ± 11.06 cm3, −1.03 ± 8.09 cm3 and 1.31 ± 2.63 cm3, respectively. While there was no significant difference for the point and mean doses between the 100% 3D shell filled with water and the VB plans (P> 0.05), the intraclass coefficients for these dose metrics for the 100% 3D shell filled with wax compared to VB doses (0.69–0.96) were higher than those for the 18% and 100% 3D shell filled with water and the wax (0.48–0.88). Average costs for staff time and materials were higher for the wax ($138.54 and $20.49, respectively) compared with the 3D shell prints ($10.58 and $13.87, respectively). Conclusion Three‐dimensional printed bolus replicated the VB geometry with less cost for manufacture than wax bolus. When shells are printed with 100% infill density, 3D bolus dosimetrically replicates the reference plan.

“…Tensile strength was maximum at low layer thickness and high infill density; however, unlike other research, it was shown that tensile strength was maximum at low print speed. Rodríguez-Panes et al [85] compared the tensile properties of FDM built ABS parts and PLA parts by varying layer thickness, infill density, and build orientation. The tensile properties (modulus of elasticity, nominal strain at break, yield stress, and tensile strength) of PLA were better than the case of ABS.…”

Fused deposition modeling (FDM) is an additive manufacturing (AM) process that is often used to fabricate geometrically complex shaped prototypes and parts. It is gaining popularity as it reduces cycle time for product development without the need for expensive tools. However, the commercialization of FDM technology in various industrial applications is currently limited due to several shortcomings, such as insufficient mechanical properties, poor surface quality, and low dimensional accuracy. The qualities of FDM-produced products are affected by various process parameters, for example, layer thickness, build orientation, raster width, or print speed. The setting of process parameters and their range depends on the section of FDM machines. Filament materials, nozzle dimensions, and the type of machine determine the range of various parameters. The optimum setting of parameters is deemed to improve the qualities of three-dimensional (3D) printed parts and may reduce post-production work. This paper intensively reviews state-of-the-art literature on the influence of parameters on part qualities and the existing work on process parameter optimization. Additionally, the shortcomings of existing works are identified, challenges and opportunities to work in this field are evaluated, and directions for future research in this field are suggested.

“…The results were prepositioned with an empirical model to understand the impact of each process parameter [20]. However, by scrutinising literature, it is found that the display of mechanical properties of specimen produced with PLA exhibits better results as compared to ABS specimen [21]. During the review, it is found that there are very few papers on the mechanical behaviour of PLA parts processed by lowcost 3D printers.…”

Fused deposition modelling (FDM) is one of the additive manufacturing technique, widely accepted due to its 'easy to use' technology. The set process parameters during FDM printing, affect the mechanical behaviour of the built part. The objective of this study is to investigate the effect of variable infill density on the tensile and impact strength of polylactic acid (PLA) specimens printed by an open-source 3D printer. The tensile and impact test specimens are printed according to the DIN EN ISO 527-2, ASTM D256 (Izod) and ASTM D6110 (Charpy) respectively. A computerised tensometer and impactometer used to conduct the tensile and the impact strength of the PLA specimens. The tensile strength with the highest value of 46.3 N/mm 2 and the lowest value of 29.9 N/mm 2 are found. The results demonstrate that the specimens with varying infill density exhibit better tensile strength than the specimens with single infill density. The varying infill density specimens weigh lighter as compared to single infill density, which saves the raw material. The highest Charpy and lowest Izod strength found to be 4.72 kJ/m 2 and 1.7 kJ/m 2 . The impact test experimental data establishes that impact strength is directly proportional to the infill density. Thus, by varying the infill density, there is a reduction in the impact strength of the printed specimens.
