Abstract: Auxetic structures exhibit negative Poisson’s ratios in one or more directions. When stretched, they will become fatter or become thinner when compressed, in contrast to conventional materials. The present work intends to provide an overview of the current state of the art in the area of auxetic cellular structures for customized orthopedic implants, using advanced AM techniques. The present work also highlights the existing limitations in addition to future prospects in fabrication via AM techniques.
