Abstract Scope |
This study was conducted by graduate students in a semester-long additive manufacturing laboratory class as part of the term project. The goal is to develop deposition parameters for SS316L on the Freemelt-ONE Electron Beam Powder Bed Fusion machine in a span of four weeks and using only one build. Due to the lack of established parameters for SS316L particularly for Freemelt-ONE, a simple analytical model was used in conjunction with defect criteria and established process conditions for the laser powder bed fusion (LPBF) process to quickly develop an initial set of process parameters - power, velocity, and hatch spacing. Results will focus on defects and overall process viability. This work highlights the effectiveness of a simplified strategy in determining preliminary process parameters by leveraging the established knowledge in the LPBF process. It paves the way for subsequent fine-tuning and optimization through comprehensive experimental characterization or high-fidelity modeling for SS316L. |
