As well known, epoxy acrylate resins have been
widely used in 3D SLA printers applications. Epoxy acrylate system consisted of
bisphenol-A glycerolate diacrylate (epoxy acrylate resin) and 1,6-Hexanediol
diacrylate (HDDA, reactive diluent resin) were used in this study. The weight
ratio of epoxy acrylate and HDDA was determined as 1/1. The purpose of this
study is to develop a novel epoxy acrylate system for 3D SLA printers and
observe its properties. For this reason, a novel urethane acrylate was
synthesized as reactive resin and was added into epoxy acrylate system with
various weight percents. In order to obtain this novel urethane acrylate resin,
hydroxyl terminated butadien oligomer was used as backbone of the chain while
isophorone diisocyanate (IPDI) and
2-Hydroxyethyl methacrylate (HEMA) were used for synthesizing urethane acrylate
functional groups. The addition of this novel reactive resin was carried out up
to 1.5 %. Mechanical and physical tests were applied to the produced samples
such as tensile, Shore-D hardness, abrasive and density tests. Considering of
the results, substantial increases were observed in terms of tensile modulus.
As expected, tensile strain values presented large decreases. Shore-D hardness
and densities presented slight increases. Moreover, taber abrasive resistances
of the produced novel samples presented considerable increases.
