“…Polymers are characterized by the ease of fabrication, modification, and functionalization as compared with other classes of materials. It has been also mixed with other classes of materials to make composites that provide the combined advantages of the components of these composites for a wide range of applications [1,2]. Structural modifications of polymers extend these applications and overcome any possible shortcomings a single polymer may have.…”

Polymers provide a wide range of properties, and these properties can be greatly enhanced and modified through polymer blending. Polymer blending combines the properties and advantages of their original polymers. is paper showcases hydrophobic polymers prepared through polymer blending; these blends are characterized and evaluated for their efficiency in the removal of crude oil spills from aqueous media. e application of these blends holds a great deal of importance in preserving the environment and the recovery of lost oil in spills. e blends are produced using polystyrene (PS) as the matrix polymer and individually blending poly(vinyl chloride) (PVC) and polyethylene (PE) with the PS consisting of proportions of 5-20 wt.% each. e blends are then electrospun into bead-free microfibers with interconnected porosities as shown by their respective scanned electron micrographs. All fibrous sorbents showed a high affinity towards the removal of crude oil, motor oil, and diesel spills. e highly viscous motor spill showed a different pattern of sorption onto fibers than that of crude oil and diesel spills. Upon comparing all the studied electrospun fibers to commercially available polypropylene fibrous sorbents, results show that the sorption efficiency of the electrospun fibers is superior. Most notably, both PS-PE5 and PS-PVC5 fibers showed to be highly more effective than commercially available polypropylene (PP) sorbents towards all types of oil spills.

“…The open-source software Ultimaker Cura 4.4 was used to communicate with Ultimaker S 5 and set the printing parameters, while ideaMaker 3.4.2 was used for Raise Pro2. Two commercial thermoplastic polyurethane (TPU) filaments were used as non-sensitive elements: for Ultimaker S 5 , TPU 95 A developed by Ultimaker Itd was used, while for Raise Pro2, TPU 90 A produced by Fabbrix was chosen.…”

“…Generally, powder bed fusion (PBF) and direct energy deposition (DED) are the AM categories mostly involved in this field [1], which are used for the fabrication of complex geometries and for repairing critical components [2]. Nowadays, the improvement of an advanced algorithm in laser cladding technology (applicable both to direct manufacturing and to repair) used for the homogenous material deposition of disk blades [3], the development of a new methodology to inspect the reliability of AM components based on stochastic defect-propagation analysis [4], and advances in fiber-reinforced polymer composites and aluminum alloy lattice structures [5,6], paves the way for a wider use of AM technologies in the aerospace industry. AM has been used for monitoring structures by embedding sensing elements [7], which can compete with other approaches based on time-domain reflectometry [8].…”

Nowadays, a challenging scenario involving additive manufacturing (AM), or 3D printing, relates to concerns on the manufacturing of electronic devices. In particular, the possibility of using fused filament fabrication (FFF) technology, which is well known for being very widespread and inexpensive, to fabricate structures with embedded sensing elements, is really appealing. Several researchers in this field have highlighted the high electrical resistance values and variability in 3D-printed strain sensors made via FFF. It is important to find a way to minimize the electrical resistance and variability among strain sensors printed under the same conditions for several reasons, such as reducing the measurement noise and better balancing four 3D-printed strain gauges connected to form a Wheatstone bridge to obtain better measurements. In this study, a design of experiment (DoE) on 3D-printed strain gauges, studying the relevance of printing and design parameters, was performed. Three different commercial conductive materials were analyzed, including a total of 105 printed samples. The output of this study is a combination of parameters which allow both the electrical resistance and variability to be minimized; in particular, it was discovered that the “welding effect” due to the layer height and printing orientation is responsible for high values of resistance and variability. After the optimization of printing and design parameters, further experiments were performed to characterize the sensitivity of each specimen to mechanical and thermal stresses, highlighting an interesting aspect. A sensible variation of the electrical resistance at room temperature was observed, even if no stress was applied to the specimen, suggesting the potential of exploiting these materials for the 3D printing of highly sensitive temperature sensors.

“…Considering the recent development of 3D printing technology and the increasing potential of the technology’s application in many different fields, it is important to establish the mechanical properties of elements made in this way [ 4 , 5 ]. There are works describing certain features and mechanical (material) properties of such materials [ 6 , 7 , 8 , 9 , 10 , 11 , 12 ], including product documentation of the raw material supplied by the manufacturer. However, most of them primarily concentrate on testing the material in steady states and on slow changes in essential parameters, such as the load.…”

This paper considers issues related to the assessment of the mechanical properties of elements made with 3D printing technology. To enable experimental testing, an automated test stand was built to perform amplitude and phase angle measurements of any point of the specimen. A contactless, optical measurement method was selected, as it is especially adequate when it comes to elements with small dimensions and masses. One innovative element of the test stand is the original method of phase angle measurement using a single vibration sensor fitted with a system forcing and ensuring full measurement synchronization and dynamic state repeatability. Additionally, numerical models of tested objects were produced and simulations of their oscillations were performed. Based on that, the properties of the tested material (PLA) were considered, with a special focus on the density, elastic modulus, and damping. The analyses were conducted for a few elements with different dimensions at different vibration frequencies.
