Metamaterials exhibit properties beyond those exhibited by conventional materials in
conventional scenarios. These have been investigated both theoretically and experimentally …

The concept of metamaterials originates from the proposal of left-hand materials with
negative refractive index, followed by which, varieties of metamaterials with kinds of fantastic …

Mechanical metamaterials and phononic crystals enable localizing, focusing, and guiding of
elastic or acoustic waves in various ways. Here, we describe the physical mechanisms …

The use of 3D printing for rapid tooling and manufacturing has promised to produce
components with complex geometries according to computer designs. Due to the …

The objective of this study was to compare the physical and mechanical performance of poly
(lactic acid)(PLA), acrylonitrile butadiene styrene (ABS), and nylon 6 fabricated using fused …

Successful regeneration of weight‐bearing bone defects and critical‐sized cartilage defects
remains a major challenge in clinical orthopedics. In the past decades, biodegradable …

Additive Manufacturing technology has a significant impact on the modern world because of
its ability to fabricate highly complex computerized geometrics. Pure 3D-printed polymer …

Meta-materials are structures when their small-scale properties are considered, but behave
as materials when their homogenized macroscopic properties are studied. There is an …

This paper first reviews manufacturing technologies for realizing air-filled metal-pipe
rectangular waveguides (MPRWGs) and 3-D printing for microwave and millimeter-wave …

Polylactic acid (PLA) filaments are very popular as a thermoplastic source used in the 3D
printing field by the “Fused Deposition Modeling” method in the last decade. The PLA market …
