Abstract

The fact that numerous 3D printed products have been developed, there are still issues with the printed product’s physical properties and the accuracy of 3D printing produced product. This study examines comprehensive study on SLS 3D printer polyamide 12 recycle parameter and dimension measurement accuracy effect on maintenance application. A variable parameters of laser beam power and layer thickness recycled material were used for the Polyamide 12. The test specimens were prepared at different process parameters using the SLS 3D printer. The hardness, surface roughness, and surface morphology were tested. These samples were tested in accordance with ASTM D638-(IV) for tensile strength and roughness using a 10 mm x 10 mm coated sample prepared for scanning in an electron microscope. The SLS Farsoon 402P machine calibration block was used to measure and analyze how accurate the machine's X and Y axes were in terms of their measurements. This project will compare and validate 3D scanner data accuracy. By doing this, the researcher will get an exposure to reverse engineering software and fabricate experiment specimens using 3D printer machines. After run the experiment, the result to be expected are hardness test, roughness test, surface morphology, and dimension accuracy for each different parameter settings of SLS 3D printer machine on the specimens.
