“…[8] The presence of carbon and oxygen in such a large amount confirms the high degree of biodegradation of Arboblend V2 Nature, because they contain chemical elements that are found in abundance in the chemical structure of plants, under different types of oxygen-carbon bonds (specific for cellulose, hemicellulose, lignin, lignin derivatives, and more). [9,10] The in-line analysis reflects the structural homogeneity of the injected samples, as it is observed that the graphs do not show a maximum or a minimum, the distribution of chemical elements being approximately constant for the entire analyzed surface, (20 × 20) µm.…”

In order to identify the structure and morphology of the resulting surfaces from the abrasive water jet cutting, specialized analyses are performed. The biopolymers subjected to cold processing are Arboblend V2 Nature and Arbofill Fichte. According to the recorded data from the SEM (Scanning Electron Microscopy) and EDX (Energy-dispersive X-ray spectroscopy) analyses, uniformity as well as structural and morphological homogeneity of the samples is highlighted, together with the effect of the abrasive material, Garnet, on the structure and chemical composition of the cut surfaces. The abrasive outcome is found in the form of small streaks that has little influence on the roughness of the cut surfaces. Considering the obtained results, these biopolymers can be processed by cutting with an abrasive water jet in the conditions of obtaining a corresponding surface quality.

“…Moreover, soft filament will buckle causing poor material extrusion leading to poor part fabrication. Thus, the FDM process is incompatible for soft filament materials such as elastomers and thermoplastic elastomers [12,13]. On the other hand, the DIW technique could be employed to print soft materials like elastomers or thermoplastic elastomers (TPEs) in liquid or semi-liquid phases [14][15][16].…”

Additive manufacturing of thermoplastic elastomeric material (TPE) using direct ink writing (DIW) based printing technique opens new horizons for various applications. However, the most crucial process in DIW 3D printing is the optimization of printing parameters to obtain high-quality products both in terms of aesthetics and strength. In this work, statistical models were developed considering layer height, print speed, and, ink concentration to obtain the optimized print quality product from the blend of thermoplastic polyurethane (TPU)/ epichlorohydrin − ethylene oxide − allyl glycidyl ether elastomer (GECO) based TPE materials. Experiments were designed according to the central composite design (CCD) scheme and the influence of input printing parameters on shrinkage and tensile strength was analyzed. The significance of each parameter was systematically studied using the response surface method. For both responses, shrinkage, and tensile strength, printing speed was found to be the most significant parameter. Ink concentration significantly affected tensile strength with a contribution of ∼ 34%. On the other hand, the layer height, with a contribution of ∼ 22% significantly affected the shrinkage behaviour of the 3D printed sample. Finally, multi-objective optimization was performed using a genetic algorithm to identify the optimal 3D printing parameters of the developed TPE materials.
