AB  - We use 3D printing to manufacture lattices with uniform and graded relative density, madefrom a composite parent material comprising a nylon matrix reinforced by short carbon fibres.The elastic-plastic compressive response of these solids is measured up to their densificationregime. Data from experiments on the lattices with uniform relative density is used to deducethe dependence of their elastic-plastic homogenised constitutive response on their relativedensity, in the range 0.2-0.8. This data is used to calibrate Finite Element (FE) simulations ofthe compressive response of Functionally Graded Lattices (FGLs), which are found in goodagreement with the corresponding measurements, capturing the salient features of the measuredstress versus strain responses. This exercise is repeated for two lattice topologies (body-centredcubic and Schwarz-P). The phenomenological constitutive models produced in this study canbe used in topology optimisation to maximise the performance of 3D printed FGLs componentsin terms of stiffness, strength or energy absorption.
