Abstract Scope |
Microscale models based on discrete element methodology (DEM) to simulate the laser sintering of a single track of hydroxyapatite (HAP) bioceramic powder bed were developed. The goal was to use numerical modeling to understand how the particles respond to laser energy and form sintered bonds. The laser was defined using the Gaussian energy distribution and ray tracing method. Furthermore, the numerical codes were coupled with the DEM solver (Altair EDEM) to simulate a limited-scale, single-layer 3D printing process. The simulations were optimized and validated with similarly implemented single-track experiments. |
