Abstract :Selective laser melting insert ignore into journalissuearticles values(SLM); is an additive manufacturing process to fabricate three-dimen- sional structures by fusing powder particles using a computer-guided laser source. The SLM process can produce lightweight bespoke designs, having high strength comparable to con- ventional components. However, the developed surface texture and some of the mechanical properties are still sub-standard compared to the conventional components. The process un- certainty can produce inconsistency in parts’ properties, even those prepared concurrently, affecting SLM parts` repeatability and quality. Therefore, designing applications based on the most probable outcome of the desired properties can embrace process uncertainty. Weibull distribution is a statistical-based probability distribution method that measures the likelihood of the values’ occurrence of any random variable falling in a specific set of values. In this study, the Weibull distribution measured the relative likelihood insert ignore into journalissuearticles values(90% probability); of the compressive yield, and ultimate strength of the SLM prepared AlSi10Mg samples in a given 22 random sample size. The results showed that the compressive yield and ultimate strength fall between 321 MPa to 382 MPa and 665 MPa to 883 MPa.
