Description

<p>In this work, we present a comparison of the mechanical properties of 3D printed structures with respect to the printing orientation for 3D gel printer "SWIM-ER" and FDM (Fused Deposition Modeling) 3D printer with a result that the fracture surface of the 3D modeled object of the gel does not break along the stacked line, and the maximum stress at that time is the breaking strength. Also, the fracture surface of the 3D model of the ABS resin has broken along the stacked line other than 0 degrees, and the maximum stress at that time is the peel strength. The yield point can be observed at the 0 degree specimen, the maximum stress at that time is tensile strength. Moreover, while comparing both materials, we observed that the dependency in the stacking direction is weak in the 3D model of the gel, strong in the 3D modeled material of the ABS resin, and the dependence on the stacking direction is strongly influenced by the way of bonding the materials in stacking.</p>
