“…Furthermore, it should be noted that selecting a print method and materials are also related to other properties such as fatigue properties, microstructure, stability, etc. [197][198][199][200][201]. In the following, the mechanical properties (tensile and flexural) of various print materials and printing processes reported by bespoke studies considering various print conditions are discussed.…”

Additive manufacturing (AM) or 3D printing is a digital manufacturing process and offers virtually limitless opportunities to develop structures/objects by tailoring material composition, processing conditions, and geometry technically at every point in an object. In this review, we present three different early adopted, however, widely used, polymer-based 3D printing processes; fused deposition modelling (FDM), selective laser sintering (SLS), and stereolithography (SLA) to create polymeric parts. The main aim of this review is to offer a comparative overview by correlating polymer material-process-properties for three different 3D printing techniques. Moreover, the advanced material-process requirements towards 4D printing via these print methods taking an example of magneto-active polymers is covered. Overall, this review highlights different aspects of these printing methods and serves as a guide to select a suitable print material and 3D print technique for the targeted polymeric material-based applications and also discusses the implementation practices towards 4D printing of polymer-based systems with a current state-of-the-art approach.

“…In addition, G-code files were generated by the slicing software Cura, through which the placement position and raster angle of the 3D printer were adjusted to achieve different stacking directions. In terms of settings for the test pieces, the PLA material was printed with a spacing of 0.4 mm in the y-direction, and a spacing of 0.2 mm in the z-direction; the printing schematic and actual product are shown in Figure 3 [30]. Note that the finished product is symmetrical.…”

“…The results indicate that the part should be printed in the same direction as the tensile stress for higher strength. In 2021, Yao [30] defined three material directions to describe the orthogonality of 3D-printed materials, based on the results of electron microscope observations. A total of 27 test pieces were printed for static tests, which reveal that the Young's modulus notably varies in different material directions.…”

In this study, the orthogonal mechanical properties of additive manufacturing technology were explored. Firstly, six test pieces of different stacking methods were printed with a 3D printer, based on fused deposition modeling. The resonance frequency was measured by a laser Doppler vibrometer as the test piece was struck by a steel ball, which was used to calculate the orthotropic material constants. The accuracy of these orthotropic material constants was then verified using finite element software through a comparison of the experimental results from multiple natural modes. Thus, a set of methods for the measurement and simulation verification of orthotropic material constants were established. Only three specific test specimens are needed to determine the orthotropic material constants using the vibrating sensor technique, instead of a universal testing machine. We also analyzed the influence of different printing parameters, including raster angle and layer height, on the material constants of the test pieces. The results indicate that a raster angle of 0° leads to the highest Young’s modulus, a raster angle of 45° leads to the highest shear modulus G, and a layer height of 0.15 mm leads to the highest material strength. In various stack conditions, the mechanical properties of fuse deposition additive manufacturing can be measured by inversely calculating frequency domain transformation.

The present study highlights biodegradable and bio‐based polymer blends from poly(lactic acid), poly(butylene succinate) (PBS), and poly(hydroxybutyrate) (PHB) as potential filaments for additive manufacturing. Dog‐bone‐shaped parts were prepared using the fused filament fabrication (FFF) technique. To assess polymer compatibility, interface, and printing performance, vertical and horizontal models were prepared and compared. The ratios of PBS/PLA and PBS/PHB were fixed at 5:5 and 7:3 for this research, respectively. The design concept is based on combining high elastic modulus glassy polymers (PLA and PHB) with soft, ductile PBS. The addition of PBS enhanced thermal processing and rheological properties. Scanning electron microscopy images revealed that the blends produced high‐quality prints while maintaining the original resolution and input parameters. Tensile tests revealed that PBS/PLA blends had significantly higher performance properties than PBS/PHB blends. Vertical prints that coincided with strain direction produced significant plastic deformation in PBS/PLA blends, achieving uniform elongation values of up to 10.4% and elongation at break values exceeding 150%. PBS/PHB blends showed lower compatibility for FFF compared with PBS/PLA blends. Produced bio‐based prints showed an increase in elastic modulus and tensile properties distinct from pure‐polymers; thus, blends have excellent potential for tuning the mechanical properties of the final product.
