“…For example, in FDM, this phenomenon is attributed to factors such as air voids, raster angles, and imperfect bonding conditions [41]. Most of these factors are influenced by the printing direction and can affect properties such as toughness, hardness, bending, and proneness to fracture [42], as well as changes in permittivity (Fig. 2) [41], [43], to name a few.…”

This article offers a thorough review of the current state-of-the-art in four-dimensional (4D) printed antennas and possible adaptable designs. It provides a succinct examination of various categories of materials used in three-dimensional (3D) and 4D printing, including the utilization of smart materials available in both printable and synthesized forms. The review encompasses a concise analysis of fabrication techniques, stimuli, and response behaviors applied in various types of smart materials. These materials have the potential to fabricate antennas with tunable and reconfigurable properties, including frequency of operation, bandwidth, gain, and radiation pattern. Given the novelty of applying 4D printing in antenna technologies, the review also considers additional reconfigurable antennas with mechanically tunable properties, as well as those in non-printed formats. This exploration hints at potential adaptations to the latter for the development of 4D printed antennas. The utilization of 4D printing presents a complex yet intriguing approach to antenna fabrication, offering the possibility of creating dynamic antennas with sophisticated characteristics.

“…They considered that such parts could be used in the manufacture of components that come into contact with pathogens, for example, covers for mobile phones, mice, pens, air filters, and tool handles. The problem of the possible influence of the anisotropy of a ceramic composite material containing methacrylate and tricalcium phosphate particles from samples manufactured by 3D printing on the mechanical properties of that material was studied by Stögerer et al [ 8 ]. They concluded that, for the conditions in which the research was carried out, an isotropic behavior could not be highlighted from the point of view of the mechanical properties of the investigated material.…”

It is known that ceramic–polymer composite materials can be used to manufacture spherical bodies in the category of balls. Since balls are frequently subjected to compression loads, the paper presents some research results on the compression behavior of balls made of ceramic composite materials with a polymer matrix. The mathematical model of the pressure variation inside the balls highlights the existence of maximum values in the areas of contact with other parts. Experimental research was carried out on balls with a diameter of 20 mm, manufactured by 3D printing from four ceramic–polymer composite materials with a polymer matrix: pottery clay, terracotta, concrete, and granite. The same ceramic–polymer composite material was used, but different dyes were added to it. A gravimetric analysis revealed similar behavior of the four materials upon controlled heating. Through the mathematical processing of the experimental results obtained by compression tests, empirical mathematical models of the power-type function type were determined. These models highlight the influence exerted by different factors on the force at which the initiation of cracks in the ball materials occurs. The decisive influence of the infill factor on the size of the force at which the cracking of the balls begins was found.
