Structured cellular structures are nowadays printed using additive manufacturing methods like powder bed fusion. The relative density of the cellular structures has a big role in the suitability of a lattice for printing due to the minimum printable radius constraint and powder being trapped inside an inclusion. In this work, the theoretical limits of the printable range of relative density of different lattice types are found based on the cell size using computer methods by leaving other process parameters for further research as the current parameters are the most basic ones. The results are approximated using simple polynomials to enable practical usage. (C) 2017 Elsevier Ltd. All rights reserved.
