“…Also, besides the previously listed factors, there are others, such as necking and deposition speed. 12 The variables of FFF are adjusted 13 to improve the characteristics of the products and improve performance and processing time. In the past several years, a number of academics working on additive technologies have already been examining the effects of operating variables on the material properties of threedimensional printed samples.…”

The fused fabrication process (FFF), is one of the most popular additive manufacturing technologies used for prototyping and production applications. On the other hand, poor mechanical characteristics significantly impact the application of FFF parts, and a variety of process parameters can influence the effectiveness of parts produced with FFF. Infill density, layer thickness, print speed, and extrusion temperature are the essential FFF parameters for fabricating parts and the dimensional integrity of printed specimens. This research aims to examine the functional performance of ABS fabricated through FFF. The study’s various variables include extrusion temperature (230°C, 240°C, and 220°C), feed rate (20, 35, and 50 mm/s), and layer height (0.1, 0.15, and 0.2 mm). Based on various combinations, elongation at break, energy, tensile strength, and compressive strength will be assessed. The measured lowest tensile and compressive strengths are 25.252 and 38.52 MPa, respectively, and highest tensile and compressive strengths are 33.96 and 185.94 MPa, respectively. As a result, changing the different process variables increases tensile strength by 34.49% and compressive strength by 382.71%. Fractography analysis is also performed to understand the failure modes of specimens, indicating pulling, necking, failure of raster’s, and voids for the considered specimens. To examine the dependency and relationship of the tensile and compressive strength on the process parameters, statistical analysis is performed using ANOVA, Taguchi’s L27 array design of experiment, and regression analysis. It indicates that layer height has the most significant influence on tensile and compressive strength, followed by extrusion temperature and feed rate.

“…In this study, the FDM method 31 (also known as fused filament fabrication, or FFF) was used to produce an impeller with the closest properties to the centrifugal pump impeller produced from cast iron using ABS, high-impact polystyrene (HIPS), polylactic acid (PLA), and carbon fiber (15% carbon fiber reinforced PLA) filaments. First, mechanical tests 31 were performed on samples produced at different filling ratios to determine the optimum filling ratio, which was determined as 60%. Then, specimens made of different materials produced at this rate were tested, and the most suitable material was determined.…”

The fused deposition modeling (FDM) technique which is one of the 3D printing technologies was used to produce a centrifugal pump impeller. The fabrication and investigation of the impeller were preferred because of its complex geometry and the difficulties encountered in its production. The most commonly used ABS, HIPS, PLA, and carbon fiber filaments were preferred to compare and determine the most suitable material for the production of the impellers. Firstly, mechanical test specimens from four different materials were printed in the 3D printer according to standards. Then the tensile tests and quasi-static punch shear tests (QS-PST) were applied to determine the mechanical properties of the 3D printed parts. Also, the mechanical tests were repeated to some specimen with the different fillings to define the optimum fill rates. Secondly, the impellers were fabricated from four materials by using the 3D printer in determined fill rates. Then, these impellers were mounted in the actual pump system, and pump performance tests were performed. In the pump performance tests, the head, pump efficiency, and electric power parameters were measured against the flow rate for each impeller. Finally, the mechanical properties and pump performance of the impellers compared with the GG25 cast iron impeller which is produced by traditional technique. As a result, PLA was selected as the most appropriate material for the production of the impellers. Furthermore, PLA showed superior performance compared to others when price, production time, and product weight parameters were considered.

The current market trend and customer requirement are to find excellent quality products within shortest manufacturing time. Therefore, it is essential to analyze the processing conditions that affect the product’s quality before the actual manufacturing of the product. This study aims to experimental analysis and multi-criteria optimization of fused deposition additive manufacturing (FDAM) process for differently shaped acrylic butadiene styrene material parts. Five process variables such as raster angle, infill density, layer thickness, nozzle temperature and print head speed are considered which vary at three levels. A total of 33 experiments have been designed based on central composite design method. The surface roughness, manufacturing time and improved dimensional accuracy are considered as the response parameters in this study. Mitutoyo SJ-410 roughness tester, stopwatch and electronic digital Vernier caliper gauge are used to record the surface roughness, manufacturing time and dimensional variation, respectively. The multi-criteria optimization was performed through the technique for order of preference by similarity to ideal solution (TOPSIS) and Grey relational analysis (GRA) techniques. Concerning TOPSIS, the improvement in responses are obtained as, surface quality of concave (Racc) 8.85%, convex (Racv) 18.43%, manufacturing time (MT) 11.11%, dimensional improvement in length (δl) 1.60%, width (δw) 0.47% and height (δh) 0.46%. Similarly, the improvement found in same responses through GRA approach are Racc 7.85%, Racv 10.34%, MT 7.69%, δl 10.05%, δw 6.50% and δh 28.20%, respectively. The experimental results show that, the optimized parameters provide up to 18.43% improvement in surface quality, 11.11% saving in manufacturing time with a significant reduction in dimensional variation. The findings of this study will help the designers of functional parts to improve the quality of designed product.
