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.
