ANALISIS PENGARUH PARAMETER SELECTIVE LASER MELTING TERHADAP SIFAT MEKANIK PADUAN TI-6AL-4V GRADE 23

---

This study investigates the effect of Selective Laser Melting (SLM) process parameters on the mechanical properties of Ti-6Al-4V Grade 23, a material widely used in biomedical applications, particularly medical implants. The advancement of additive manufacturing technology has enabled the fabrication of personalized prostheses with complex geometries tailored to individual needs. Selective Laser Melting is a laser-based powder bed fusion technology that builds components layer by layer through the selective melting of metal powder using high-energy laser irradiation. Process parameters significantly influence the quality of fabricated parts, including density,and mechanical properties. The material used in this research is Ti-6Al-4V Grade 23 (ELI) powder, which offers improved toughness and ductility and is therefore suitable for medical applications. The experimental work employed a Taguchi L9+1 design, incorporating variations in laser power, scan speed, hatch spacing, and layer thickness. Specimens were fabricated using a TruPrint 2000 SLM machine and subsequently characterized through dimensional measurement, density evaluation, and tensile testing to determine the resulting mechanical properties. Overall, this study demonstrates that optimization of SLM process parameters has a significant impact on density, dimensional accuracy, and mechanical properties of Ti-6Al-4V Grade 23. Appropriate parameter combinations can produce specimens with high tensile strength and density values close to the theoretical limit, indicating strong potential for biomedical applications requiring high mechanical performance and manufacturing quality.
