High-Frequency Filters Manufactured Using Hybrid 3d Printing Method

Abstract

In this work, two different high-frequency filters were produced, and each was manufactured in two different ways, one using conventional PCB technology and the other using hybrid 3D printing. The hybrid 3D printing technique combined the use of microdispensing of conductive inks and fused filament fabrication (FFF) of thermoplastic substrates. Measurements, properties, and comparisons between these filters are discussed. The goal of the research was to benchmark 3D printing of highfrequency filters to more confidently manufacture sophisticated devices and high-frequency systems by hybrid 3D printing.

Recent Advances in Multi-Material 3D Printing of Functional Ceramic Devices

“…To enhance the microwave dielectric properties, the polymer is removed by sintering the ceramic/polymer composites or is reserved for a specific function (e.g., flexibility). The aforementioned examples of multi-material 3D printing of microstrip antennas would likely have additional applications in filters [ 247 , 248 , 249 ], resonators [ 234 , 250 ], and isolators [ 251 ].…”

A Band Stop to Band Pass Filter Transformation Utilizing 3-D Printing Technique for C-band Applications

“…It can be used to construct antenna models for multiband applications as in [16][17][18][19]. Additionally, there are various designs of microwave filters based on 3D printing in the RF frequency range [20][21], and the implemented BPF in [22] was operated in the E-band (60-90 GHz) of the millimetric wave frequency range, but with inconsistent simulation and experimental results due to fabrication tolerance.…”

“…In contrast, a planar metal structure can be easily obtained by numerous methods, such as 3D-printing technology, , silk-screen printing, , and printed circuit board technology. , Therefore, it would be a good choice once a three-dimensional structure could be constructed from a flat structure, which is the characteristic advantage of origami. Besides, compared with 3D-printing technology, origami has the advantages of fast processing speed and no complicated modeling process .
