Influence of processing parameters on the evolution of melt pool, porosity, and microstructures in Ti-6Al-4V alloy parts fabricated by selective laser melting
J. J. S. Dilip,J. J. S. Dilip,Shanshan Zhang,Chong Teng,Kai Zeng,C. Robinson,Deepankar Pal,Brent Stucker +7 more
TL;DR: In this paper, the effect of laser power and scan speed on the evolution of melt pool, porosity and multiple thermal cycling effects on the microstructure in parts fabricated using selective laser melting was investigated.
Melt Pool Characterization for Selective Laser Melting of Ti-6Al-4V Pre-alloyed Powder
Haijun Gong,Hengfeng Gu,Kai Zeng,J.J.S. Dilip,Deepankar Pal,Brent Stucker,Daniel Christiansen,John J. Lewandowski +7 more
TL;DR: In this paper, a method for rapid optimization of parameters based on melt pool characterizations was developed to accelerate the optimization process for metal powders in Selective Laser Melting (SLM).
Journal ArticleDOI
An Integrated Approach to Additive Manufacturing Simulations Using Physics Based, Coupled Multiscale Process Modeling
Journal ArticleDOI
Comparison of 3DSIM thermal modelling of selective laser melting using new dynamic meshing method to ANSYS
TL;DR: In this article, a finite element model is developed which uses a dynamic mesh with spatial nonlinear thermal properties to track the point of laser exposure on the powder bed to study thermal evolution during SLM.
