Abstract
In this study, we have explored the potential application of three-dimensional (3D) lattice-structured
materials in the bone scaffold implants by investigating the mechanical strength and porosity of various
strut-based lattice designs. The aim is to propose a scaffold design that is strong enough to support the
surrounding bone structure. Furthermore, the design should be porous enough to provide effective permeability
that allows the integration of bone cells. Therefore, four different lattice-structured material
samples with equal dimension of 50 mm in length, width, and height comprising of twenty-five lattice
unit cells are designed and fabricated by Fused Filament Fabrication (FFF) 3D printing technique using
polylactic acid (PLA) material. The samples have been investigated under compression loads by means
of the universal test machine and then the strength of each lattice is measured. Furthermore, the porosity
of each design is calculated to complete the investigation on the balance between the mechanical
strength and porosity. Finally, the chosen lattice structured material from the investigation steps is prototyped
into the imaginary damaged femur bone and fabricated with additive manufacturing to demonstrate
the closed loop of design and implementation process.
