On anisotropy, strain rate and size effects in vat photopolymerization based specimens

摘要: Abstract The influence of build orientation, layer thickness, strain rate and size effect on the Young’s modulus, ultimate tensile strength fracture strains in vat photopolymerization based additively manufactured specimens is investigated. Mechanical testing subsequent scanning electron microscopy tests are conducted. Anisotropy mechanical behavior only observed fabricated different planes. An increase thickness decrease resulted lower strength, stiffness higher strains. No significant failure observed. Cure kinetics found to have properties specimens.
