SURFACE ROUGHNESS QUALITY, FRICTION AND WEAR OF PARTS OBTAINED ON 3D PRINTER

The achievement of the required roughness of the surface (today known as surface texture) is of great importance in obtaining the required characteristics of the parts from the aspect of reduction of friction and wear. The most common methods for obtaining the required roughness, or surface textrure, are laser treatment and micro-processing by milling. 3D printingis increasingly being used to produce parts of wide range of applications. In order to obtain the neccessary surface texture, the use of 3D printing technology compared to traditional technologies is faster, more flexible and cheaper. So far, a small number of studies have been related to the surface characteristics of parts produced by 3D printing.Therefore, all the researches in this field in order to improve the friction and wear characteristics have significant role.This work provides an insight into the research of tribological characteristics of surface of samples made from polymers which are most commonly used materials in 3D printing technologies. The surface roughness, friction and wear are measured using tribometer and experimental method „Block-on-Disk“. The results shows significant differences in measured values in the tested materials, which demand further researches in order to.
