Dielectric properties of materials for 3D printing at high frequencies

Popis výsledku v původním jazyce

3D printing is a widely used method. In terms of developing components for electronic devices, it is important to provide good physical properties of the used dielectric. The main parameters are the optional and stable value of the relative permittivity and the minimum dielectric losses of the material. The paper focuses on testing the loss factor and relative permittivity of the following materials: polylactic acid (PLA, in two dye modifications), polyethylene terephthalate glycol (PETG) and acrylonitrile butadiene styrene (ABS) in the frequency range of 1 to 100 MHz. It was proven that the values of permittivity of the tested materials were 2,9 to 4,2 and the loss factor was 0,8 to 4%. Concerning the relative permittivity, the tendency to show a mild linear drop was observed by increasing the frequency, especially expressed in the PLA materials. With the loss factor, the PLA materials displayed increasing values with an increasing frequency, whereas a declining curve was observed in the PET-G materials. The absolute value of the ABS loss factor varied between 0,9 to 1,5%. The reasonable influence of added dyes was elucidated upon.
