As well known, epoxy acrylate resins has been
widely used in 3D SLA printers applications. Epoxy acrylate system that
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 Bisphenol-A glycerolate diacrylate 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
polydimethylsiloxane containing urethane acrylate was synthesized as reactive
resin and added into epoxy acrylate system with various weight percents. It is
also well known that polydimethylsiloxanes increase thermal properties of
polymer materials. In order to obtain this novel reactice urethane acrylate
resin, hydroxyl terminated polydimethylsiloxane 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 % into epoxy acrylate
system. Mechanical and physical tests were applied to the produced samples such
as tensile, Shore-D hardness, abrasive and density tests. Considering of the
results, tensile strength and modulus exhibited substantial increases while
tensile strain presented large decreases. Taber abrasive resistance showed
considerable increases. While Shore-D hardness of the produced novel materials
presented slight decreases, the densities showed almost no change
