“…Although Charpy tests may result in higher impact resistance and energy [90], lower values were obtained in previous studies with PC/ABS and FFF or FGF 3-D printing systems. For example, Verma and Banerjee reached ~15 kJ/m 2 of impact energy [91], whereas impact resistance values of ~350 J/m and ~200 J/m were obtained from Kumar et al and Peng et al [92,93]. The percentage of ABS can mainly influence these differences in PC/ABS blends characterized in these studies, i.e., 75% wt., and from the different scales of the 3-D printing process, mainly desktop-size small-format apparatuses.…”

“…[134] They achieved this elongation due to the elastic nature of the TPE. [135][136][137][138][139][140][141][142] Hopmann et al [143] produced injection molded robust superhydrophobic surfaces using liquid silicone rubber as a substrate with a water contact angle of 150 , resulting in a self-cleaning surface. The molded microstructures consisted of conical pillars having a diameter of 5-20 μm, height-to-diameter ratios of 0.25:1 and a small peak-topeak distance of 1.5:1.…”

Functional surfaces with attractive properties, such as superhydrophobicity and omniphobicity often rely on the synergy between intrinsic material properties and dual scale micro‐ and nano‐hierarchical structures for achieving desired wettability. Historically, engineered liquid repellent surfaces have attracted a great deal of interest from academia and industry due to their broad application prospects. Hence, for several years, there have been significant scientific efforts by researchers exploring state of the art manufacturing technologies that are efficient and yet cost effective to produce functional liquid repellent surfaces at an industrial scale. This technical review summarizes the various advanced and state of the art polymer processing technologies employed to fabricate the micro‐ and nanostructured polymer surfaces, with a special focus given to superhydrophobic and omniphobic applications. Here, we discuss the merits and limitations of each fabrication methods available for micro‐ and nanostructuring of polymer‐based surfaces. In addition, an attempt has been made to provide insight into the relationship between geometry of micro/nanostructures (size and shape) and intrinsic wettability on liquid repellency. A special section has been devoted to feature and document all commercialization efforts, including various commercially available products that were developed in the past decade. Finally, outlook and the development trend in the polymer micro‐ and nanostructured surfaces are highlighted to lead future research.

“…PC materials are considered environmentally friendly materials which are suitable for 3D printing [20]. Owing to its chemical characteristics, PC demonstrates very good chemical resistance [30,31], which is very important for relevant applications. Also, PETG exhibits good chemical resistance and is characterized by significant durability and formability [32,33].…”

In this study, we successfully address a significant research and engineering gap by quantitatively assessing the impact of varying compressive loading rates on the mechanical behavior of four popular thermoplastic polymers in material-extrusion-based (MEX) 3D printing. Raw powders of polycarbonate (PC), polyethylene terephthalate glycol (PETG), polymethyl methacrylate (PMMA), and thermoplastic polyurethane (TPU) were processed through melt extrusion, and the filaments were used to 3D-print the test samples. For completeness, thermogravimetric analysis and a compressive test following the ASTM-D695 standard were conducted. Ultimately, the compressive strength and yield stress, the compressive modulus of elasticity and toughness, and the maximum compressive sensitivity index were thoroughly documented. Specimens were tested in strain rates from 1.3 mm/min to 200 mm/min. The compressive strength (40% for the PMMA) and stiffness (29% for the TPU) increased with the increase in the strain rate in all polymers tested. PC had the highest strain rate sensitivity. Significant variations in deformation and fracture modes were observed and thoroughly documented throughout this study. Our findings can be useful in industrial engineering as valued design optimization input parameters in various applications involving the above-mentioned polymeric materials.
