Abstract:

The specimens made of polyamide-12 and Portland Cement mixture were prepared using Selective Laser Sintering (SLS) of Lisa PRO Sinterit Studio to test its mechanical testing in response to a laser power parameter. The polymer-cement mixture powder was sintered into a compact structure to form durable, strong, and functional plastic parts by using SLS. SEM and thermogravimetric analysis were used to determine the composite’s morphology and thermal properties. With the aid of a VORTI-SIV pilot sifter machine, a homogenous powdered mixture material of polyamide-12 and Portland Cement was created. An SLS system slices the specimen thickness into 0.075 mm layers to produce the test specimen. This is so that test specimens can be manufactured from a 3D-CAD file. This study was conducted to evaluate the optimal laser power that would produce better properties and an improved final product. Results showed that increasing laser power significantly improved the prepared specimen composite’s tensile, compressive, and flexural strength.
