Marking on polyamide is an important process because this type of material is widely used in many industrial sectors. Also, laser marking is a popular and easily automated method. But materials like polyamide have several properties, such as white colour, that make laser marking a complicated process. White colour has low laser absorption, so good marking results are difficult to achieve. Different types and parameters of the laser system are used for marking polyamide. To improve the marking results on polyamide, auxiliary materials are often used, which are applied to the polyamide surface. However, the most promising ranges of marking parameters without incorporating auxiliaries on the polyamide surface are still unknown. Successful marking on polyamide requires a deep study of parameters and various conditions. The aim of this study is to reveal the different possibilities for laser marking of polyamide and how different processing parameters respond to laser irradiation.
