Abstract

In the present study, the surface roughness values of the models produced by different open nozzle temperatures by an open source three-dimensional printer were examined and the effect of the temperature parameter on the surface roughness was investigated. All models are produced by adding solid material. A low-cost open source coded 3D printer was used to produce these materials. Polylactic acid (PLA) was used as the main polymer material for printing. The nozzle with temperatures of 180 °C, 190 °C, 200 °C, 210 °C, 220 °C, and 230 °C was tested whether 3D printed models are effective in roughness. In this study, where the surface roughness was measured as the average (Ra-μm), it was found that the surface roughness value showed a decreasing trend with increasing temperature.
