Experimental Investigation on Mechanical Properties of 3D Printed ABS, PLA and PETG Specimen Processed by Fused Deposition Modelling Method K. V. Durga Rajesh, Tanya Buddi Journal of Physics Conference Series, 2026 Technologies for additive manufacturing have significantly improved in recent years for component fabrication. Fused Deposition Modeling (FDM) additive manufacturing approach is one of the most frequently employed technique in fabricating the component by depositing the material layer by layer. Understanding the mechanical properties of thermoplastic materials that may be 3D printed is important since they have many uses in the medical and aerospace industries. In compliance with ASTM guidelines, 3D-printed Acrylonitrile Butadiene Styrene (ABS), Polyethylene Terephthalate Glycol (PETG), and Polylactic acid (PLA) specimens were produced. In this paper, studies are conducted to examine mechanical characteristics such as compression, bending, and tension of 3D printed ABS, PETG, and PLA samples. Ansys software was then used to compare and evaluate the data. Results on tensile, bending, and compression properties are examined and contrasted in detail with ABS, PETG, and PLA. The findings in this paper offer thermoplastic manufacturing guidelines, allowing for the layer-by-layer printing of novel functional polymers.
Optimization of SLM Process Parameters for IN625 to Achieve Higher Surface Quality and Microhardness Podisetty Yasaswi, Sindhanur Jagadeesh, Ramatenki Chinna, Boggarapu Nageswara Rao, Tanya Buddi Journal of Physics Conference Series, 2026 This paper deals with the optimization of selective laser melting (SLM) process parameters for IN625. The fabrication of test samples from commercially available nickel alloy IN625 metal powder with an average size of 35 ± 6 μm using an EOSINT 280 SLM machine in an inert argon atmosphere. The SLM process utilized a Nd:YAG fiber laser with varied parameters including laser power. LP (240, 270, 300 W), scan speed, SS (600, 800, 1000 mm/s), and hatch distance, HD (0.08, 010, 0.12 mm).. Taguchi’s L 9 orthogonal array (OA) selected for the three FLM process parameters (LP, SS, HD) and each assigned with three levels. The performance characteristics are the microhardness (MH) and the surface roughness (SR). The study aimed to maximize MH and minimize SR simultaneously by integrating the modified Taguchi and multi objective optimization schemes. Due to significant variation of MH and SR, the measured data was converted to natural logarithmic scale. Analysis of variance (ANOVA) performed to develop empirical relationships for MH and SR in terms of SLM process parameters. Test data found to be within the range of estimates. The optimal SLM process parameters were identified and estimates of MH and SR were comparable to the measured ones.
Optimizing the Tribological Performance of M25/SiC (5%)/Cu (3%) Composites through Integrated Modified Taguchi and Multi-Objective Approaches Gorla Ashok Chandra, Jimmala Siddhartha Reddy, Ramatenki Chinna, Boggarapu Nageswara Rao, Tanya Buddi Journal of Physics Conference Series, 2026 This paper deals with the optimization of dry sliding wear parameters for an aluminum LM25 matrix composite reinforced with 5 wt.% silicon carbide and 3 wt.% copper. The composite produced via stir casting. It was subjected to wear tests using a pin-on-disc apparatus. Taguchi’s L 9 orthogonal array (OA) selected for the three parameters (such as load, sliding velocity, and sliding distance) and each assigned with three levels. The tribological performance characteristics are the wear rate (WR) and the coefficient of friction (COF). The study aimed to minimize both WR and COF simultaneously by integrating the modified Taguchi and multi objective optimization schemes. Due to significant variation of WR and COF, the measured data was converted to natural logarithmic scale. Analysis of variance (ANOVA) performed to develop empirical relationships for WR and COF in terms of dry sliding wear parameters. Test data found to be within the range of estimates. The optimal dry sliding wear parameters were identified and estimates of WR and COF were comparable to the measured ones.
Assessment of adhesive-bonded single-lap composite joint strength using modified Taguchi and ANN approaches Kothapalli Varshitha, Katikineni Thanveer Rayanam, Ramatenki Chinna, Boggarapu Nageswara Rao, Tanya Buddi Journal of Physics Conference Series, 2026 This paper deals with the failure assessment of adhesive-bonded single-lap E-glass fiber-reinforced epoxy composite joints. Test specimens were made as per the ASTM D5868 standards. In the design of experiments, Tests were performed out using a universal testing machine (Instron 3366 with a capacity of 1 ton) by pulling the specimens at their ends at a controlled rate of 13 mm/min. Taguchi’s L 9 OA (orthogonal array) is selected with distinct combinations of overlap length ( a ) and adhesive thickness ( t a ) to assess the failure load ( P f ). Analysis of variance (ANOVA) performed to study the influence of the bonding process parameters. It is noted from the ANOVA results that the influence of overlap length ( a ) is more compared to that of adhesive thickness ( t a ). Modified Taguchi method is adopted and the developed empirical relationship for the failure load is validated through comparison of measured data. The optimal factor levels identified are: overlap length, a 3 = 35 mm and adhesive thickness, t a1 = 0.2 mm. The range of failure load ( p f ) estimated is from 5772 to 7002 N, while its measured value of 6096 N is within the estimated range. The bond shear strength can be evaluated from the failure load using the shear area. The failure assessment followed in the present study is quite simple and reliable when compared to the expensive ANN models which demand more test data.
