@article{Leu2012InvestigationOL, title={Investigation of laser sintering for freeform fabrication of zirconium diboride parts}, author={Ming C. Leu and Shashwatashish Pattnaik and Gregory E. Hilmas}, journal={Virtual and Physical Prototyping}, year={2012}, volume={7}, pages={25 - 36} }
This paper presents a study wherein the Laser Sintering (LS) process is used to perform additive manufacturing of zirconium diboride (ZrB2) parts. Experiments were conducted to determine values of LS process parameters (laser power, scan speed, energy density, line spacing, and layer thickness) that can be used to improve building of ZrB2 parts. A sacrificial plate with a proper number of layers was first constructed in order to reduce thermal gradients in building the main part. The…
