| Summary: | 3D printing technology has had a significant impact across various fields. This
technology enables printing objects by sequentially layering materials, resulting in
complex structures. This study analyzes the effect of different 3D printing resins on
the uniaxial compressive strength of 3D printed samples to simulate natural rock
properties. This research aims to identify the most effective resin type for
simulating natural rock conditions in laboratory tests. The three types of resins used
in this study are AnyCubic UV Sensitive Resin, AnyCubic ECO Plant-based UV
Resin, and Sunlu Standard Resin. These resins were then compared with natural
rocks such as andesite, limestone, and sandstone. The results indicate that the used
resins are still too elastic to model hard rocks such as andesite and limestone
however, the deformation characteristics are quite similar to sedimentary rocks such
as sandstone and siltstone. Resin has a Young's modulus range of 0.39 – 0.95 GPa
and a Poisson's ratio range of 0.39 – 0.41. The axial strain the resins produce is
quite high, reaching 8.2 – 14.6%. Several modifications can be made to improve
the mechanical properties of the resins, such as freezing and adding fractures to the
resin samples. |
