Abstract: Additive manufacturing methods have been widely used in applications for material preference in our daily lives, especially by enabling the production of complex geometry materials with precise tolerances. The purpose of being preferred in industrial applications is to produce alternative materials thanks to the Selective Laser Sintering (SLS) production system, which offers additive manufacturing. For this reason, in order to adapt the SLS system to the test samples, samples of 25x25x3mm3 were produced from recycled PA 3200 GF powders to form a layer thickness of 100 ?m.As a result of the impact of solid particles (especially aerospace systems, energy conversion plants, jet engines, helicopter rotor blades, etc.) with different properties on the material surface at certain velocity and angles, undesirable deformations occur on the material surface. In addition, this type of wear has a critical importance in the world economy. With this convergence, erosion wear tests were carried out in accordance with the international standard ASTM G76-95, prioritizing that material for the aerospace industry can be exposed to this type of wear thanks to the use of samples produced by additive manufacturing and containing recycling powders.In order to carry out solid particle erosion wear tests, especially for sand and dust effect, for the use of samples produced by SLS method and with a change in printing direction in different environmental conditions, taking into account the particle impact angle of 30°, 60° and 90°, under the influence of abrasive particles with Al2O3, SiO2 and C20 properties and experiments were carried out by modeling the operating conditions of 34 m/s impact velocity. Regardless of the printing direction effect, it was concluded that the highest erosion rate of the test materials in all groups occurred at the impact angle of 30°. Erodent properties also showed a dominant effect on the erosion wear mechanism. Moreover, the tangential and vertical efficiency of the abrasive particle impact have a significant effect on erosion wear. © 2022 IEEE.
