“…The peak values of loss tangents of the two materials were both increased by almost 8%. The sample is more dissipative as tan δ increases [ 37 ]. The increased loss tangent may be due to the deeper interdiffused of the polymer chain at the interface, which increased the friction in the molecular layer.…”

Fused deposition modeling 3D printing has become the most widely used additive manufacturing technology because of its low manufacturing cost and simple manufacturing process. However, the mechanical properties of the 3D printing parts are not satisfactory. Certain pressure and ultrasonic vibration were applied to 3D printed samples to study the effect on the mechanical properties of 3D printed non-crystalline and semi-crystalline polymers. The tensile strength of the semi-crystalline polymer polylactic acid was increased by 22.83% and the bending strength was increased by 49.05%, which were almost twice the percentage increase in the tensile strength and five times the percentage increase in the bending strength of the non-crystalline polymer acrylonitrile butadiene styrene with ultrasonic strengthening. The dynamic mechanical properties of the non-crystalline and semi-crystalline polymers were both improved after ultrasonic enhancement. Employing ultrasonic energy can significantly improve the mechanical properties of samples without modifying the 3D printed material or adjusting the forming process parameters.

Fused deposition modelling (FDM) is a process of layer-by-layer material deposition using a heated extruder. FDM printed parts have stair-stepped effect and ridge patterns that diminish surface quality. This research intends to develop a low-cost, high-efficiency experimental system for polishing a variety of materials using various chemicals, with a chemical vapour smoothening process. For evaluating the created set-up, tetrahydrofuran (THF) is used and acetone as solvents to polish polylactic acid (PLA) and acrylonitrile butadiene styrene (ABS). Taguchi multiparameter optimization was used to optimize the input parameters (reagent volume, temperature, concentration, and time) in the vapour smoothening process. With the ideal input parameters, the roughness of the FDM printed parts was reduced by over 95%. The effectiveness of a vapour smoothening system is better when the system temperature is maintained at the boiling point of the reagent, the reagent is of its highest concentration, and when the specimens placed are placed directly over the ultrasonic mist-maker. The system discussed works best with FDM printed parts having minimum porosity and better quality. The hot chemical vapour smoothing approach reduced specimen flexural strength and increased top layer wear. The findings of this study will help develop a large-scale polishing system for FDM printed thermoplastics and enhance the use of FDM components in sectors that need highly polished parts.

“…The layer thickness resulted as the most influencing parameter for viscoelastic properties of ABS parts. Zhang et al 13 examined the impact of vapor smoothing on storage modulus and tan delta. The authors also compared the dynamic mechanical analysis (DMA) results with and without post-treatment and the amount of vapor smoothing by using acetone solution.…”

Fused deposition modeling (FDM) technology is catching the fast global market in the real-time production of polymeric parts. Process variables highly influence the performance characteristics of FDM-generated parts, so mechanical performance is not perfect for all applications. In actual conditions, parts produced by FDM are constantly subjected to loading at different temperatures. The former studies mainly concentrated on the properties of FDM products to static loading environments. There is a scope of effective investigation on the influence of FDM processing conditions on dynamic mechanical properties using artificial intelligence (AI) based techniques. The present study focused on investigation and optimization the manufacturing process parameters to evaluate the dynamic mechanical performance of FDM-produced part. The experimental runs were obtained through central composite design in Minitab software. A DMA8000 instrument was used to test the specimens for dynamic mechanical performance. The mathematical models were developed and optimized through different approaches like response surface methodology-genetic algorithm (RSM-GA) and artificial neural network-genetic algorithm (ANN-GA). The techniques for order preference by similarity to an ideal solution (TOPSIS) is employed to obtain the best parameter settings from sets of optimized solutions. The sequential use of ANN-GA and TOPSIS methods predicted the highest values of storage modulus 1619.61 MPa and loss modulus 257.38 MPa corresponding to 68.94° raster angle, 81.48% infill density, 0.10 mm layer thickness, 237.73°C nozzle temperature and 38.97 mm/s print head speed. The confirmation tests were conducted to validate the predicted result that upscale the desired properties. The RSM-GA-TOPSIS occurred with a prediction error of 2.40% and −3.31%, corresponding to storage and loss modulus. Similarly, ANN-GA-TOPSIS shows 2.17% and 2.89% prediction error corresponding to storage and loss modulus. The experimental and analytical outcome of present study will be helpful for the designers of intricate functional parts which come under thermo-mechanical loading conditions.
