During this presentation, Miller will describe how lattice structures can be applied to aerospace manufacturing. The honeycomb design makes these structures sensitive to variables like build orientation, layer thickness, deposition and fusion—none of which are accounted for in current, lattice structure models. Throughout the presentation, Miller will discuss a valid, physics-based model that provides a more accurate estimation of the mechanical properties of lattice structures made out of the most common additive manufacturing processes. These include fused deposition modeling (FDM), laser-based powder bed fusion (Laser-PBF) and electron beam melting (EBM). This methodology can also be applied to other additive manufacturing processes and materials. These findings come from PADT’s study: A Non-Empirical Predictive Model for Additively Manufactured Lattice Structures.
- Predict lattice structure behavior more accurately
- Apply these findings to FDM, Laser-PBF, EBM and other additive manufacturing processes
- Increase design flexibility, lower material costs and reduce production time in aerospace applications
