As well known, epoxy acrylate resins have been widely used in SLA 3D
printers applications. Epoxy acrylate systems have generally consisted of
bisphenol-A glycerolate diacrylate (epoxy acrylate resin) and 1,6-Hexanediol diacrylate
(HDDA, reactive diluent resin). The purpose of this study is to develop novel
epoxy acrylate systems for 3D SLA printers and observe the properties of
produced materials. For this reason, novel modified graphene oxide phases were
synthesized. First, graphene oxide was synthesized by Hummers method. Then
aromatic diisocyanates (TDI;toluendiisocyanate and IPDI; isophorone
diisocyanate) and 2-Hydroxyethyl methacrylate (HEMA) were reacted with graphene
oxides in THF solvent. These modified graphene oxide solutions were entegrated
into epoxy acrylate system. Tensile,
izod impact resistance, shore-D hardness, abrasive and density tests were
applied to the produced materials. Considering of the results, substantial increases
were observed in terms of tensile strength and modulus, izod impact resistance,
taber abrasive resistance and shore-D hardness. Moreover, densities of the
produced novel samples presented considerable increases.
