Material use optimization in 3D printing through a physical simulation algorithm. Automation in Construction, 78, 24-33. DOI: 10.1016/j.autcon.2017.01.0170926-5805http://hdl.handle.net/11268/7127This paper focuses on the design of an algorithm for a structure-based infill patterning system for big-scale 3D printed parts. A simple, modular, expandable system is presented that considers the structural logic of printable parts through the voxelization of 3D virtual models into a finite element representation that is used to feed a spring model. Material properties and user customization are discussed. Several ad-hoc solutions, optimization capabilities and simulation results are tested and shown. The use of non-standard, customized nozzle designs and print materials is discussed for further usage capabilities.engjournal article10.1016/j.autcon.2017.01.017restricted accessArquitecturaDiseño arquitectónicoDiseño arquitectónicoArquitectura
