Metallic Parts Realization using Selective Laser Melting Machine Default Parameters
The selective laser melting (SLM) has already at its mature development stage, yet its application in Malaysian industrial sector is relevantly new. There are many factors involved in the SLM process to produce parts that meet the intended applications. This paper aims at revisiting some aspects of the SLM in terms of its product realization and few related material properties. The SLM280 machine available in one of a Malaysian business entity was being the subject for discussion. Product realization was highlighted from the perspective of machine’s intelligent and optimized process parameters. Whereas, material properties (titanium, aluminum, stainless steel and cobalt chrome) that were directly related to the default process parameters were evaluated. Parts produced from the SLM280 machine (titanium alloy) were examined for surface observation and density measurement, and the outcome was evaluated with that of calculated energy being used during the SLM process. It was found that the set of default parameters being applied in the SLM280 machine has produced a reasonably sufficient energy in the SLM powder melting process, thus ensuring a dense solid part density of up to 99.5%. The discussion in this paper has highlighted some capabilities of the SLM machine that runs according to manufacturer’s standard in producing parts that are complicated to be produced using other conventional manufacturing processes. This will be a benchmark for future analysis on parts that will be produced using the available machine.
