Manufacturing of mechanical elements with properties of metamaterials using 3D printing technology

Metamaterials are materials engineered to have properties that not found in naturally occurring materials, which opens a wide range of opportunities for creation with completely new functionalities. Auxetics type metamaterials unique because they negative Poisson’s ratio whereas positive one. shown some really promising energy absorption can be widely applicable e.g.: automotive (crash absorbers, suspension parts), medicine (prosthetics), clothing (shoe soles). Moreover, showing other superior conventional such as: increased shear modulus better acoustic behaviour improved fracture toughness and other. Methods modelling CATIA V5 software various manufacturing methods the use 3D printing technologies like MSLA (Masked Stereolithography Apparatus), Selective Laser Sintering (SLS) Fused Deposition Modelling (FDM) presented.
