Absorbing Property

Graphene/polylactic acid; nano-Fe3O4/polylactic acid; and graphene/nano-Fe3O4/polylactic acid composite absorbers are independently produced by fused deposition modeling technology. The effects of the content of graphene and nano-Fe3O4 on absorbing properties are investigated. After measuring the electromagnetic parameters using the waveguide method, the absorbing property is characterized according to the transmission line theory. The distribution of graphene and nano-Fe3O4 in the matrix is observed by scanning electronic microscopy (SEM). The results show that the graphene and nanometer ferroferric oxide multicomponent absorbing agent helps to form a synergistic absorbing effect. In the frequency range 8.2–18.0 GHz; the absorber has the greatest absorbing property when the content of graphene and nanosize Fe3O4 are 5 wt% and 20 wt%, respectively.

Plastic Parts

The paper shows the importance of designing an ABS (Acrylonitrile-Butadiene-Styrene) plastic part which will be produced using FDM (Fused Deposition Modeling) technology; it is obtained a product with the same characteristics provided by the operating guide book. Thus, this solution combines both the capacity of the designer as well as the applied technology and can produce similar or improved plastic components, at the same time maintaining the functional characteristics of the work piece. This paper is a plea for the application of 3D printing using FDM technology for manufacturing components (spare parts) out of production, because the technological systems users no longer have other solutions available for replacing outworn plastic parts. 3D printing using FDM technology is a fast option for replacing outworn components, the modeling, simulation and printing time being shorter than the purchase time of a new subassembly or assembly that has been remanufactured and modernized.

Deposition Modeling

The article deals with creating 3D models using RAPID PROTOTYPING technology. At present, we are witnessing the integration of new technologies into ordinary life. A good example is the use of FDM (fused deposition modeling) technology that primarily uses thermoplastics to create 3D models. A few years ago, the use of rapid prototyping technology was a prerogative of companies, research institutes and a narrow group of universities. Technologies such as FDM and STL (Stereolithography) have become affordable in the past few years for smaller businesses and individuals. The specific segment is the replicating rapid prototype RepRap (replicating rapid prototype), the extended version of which is the Prusa i3 printer.

The Operating Mechanism

A circularly polarized (CP) wearable antenna based on the FDM (fused deposition modeling) technology is proposed. Conductive fabric is used to realize conductive parts of the patch antenna on the NinjaFlex substrate. The antenna is encapsulated with additional layers of NinjaFlex. Modified patch ensures the CP character at 2.45 GHz. Bending and washing tests are conducted to check the performance stability, and good agreement between simulated and measured results is observed. The experimental results illustrate that the antenna holds 11% 10 dB S11 bandwidth and around 70 MHz 3 dB axial ratio bandwidth. In addition, surface current analysis is also given to understand the operating mechanism of CP wave.
