The influence of 3D printing temperature on the impact strength of polylactide

Abstract

3D printing is one of the most developing technologies currently. There are many materials present on the market that allow you to get quite good and durable prints. One of the most commonly used materials is polylactide. The article presents the results of research on the influence of 3D stamping temperature on the impact strength of PLA filament using the Charpy test method. The paper presents the results of the impact strength of PLA samples as a function of printing temperature. In the paper compare samples printed at temperatures of 185 °C, 200 °C, and 210 °C. The highest moment of force was obtained for the 5th sample printed at a temperature of 185 °C, and the lowest for the 5th sample printed at a temperature of 200 °C, however, the values between subsequent measurements differ by a maximum of 0.11 [kpm].
