The effect of different parameters (layer thickness, jetted binder volume per layer and type of binder and temperature) on the mechanical properties of parts made with an experimental three dimensional printer (3DP) process was studied. This 3DP device built for this project is based on the SGM device previously introduced by Hauser et al. at The University of Liverpool. It differs from the common 3DP in that it generates the different parts using only one rotating piston instead of two non-rotating ones.
Several parts were produced using this device according to an experimental design, repeating
each run three times. The experimental machine was able to make every part needed without
major issues, demonstrating that it is possible to build a functional device using common and
Experimental analysis of the printed parts shows that the layer thickness has the highest effect on apparent density, hardness and fracture strength of the parts made.
Empirical information is provided about mechanical behavior (e.g., apparent density, hardness and fracture strength) of parts made under different processing factors (e.g., binder type, layer thickness, quantity of binder and chamber temperature) using a SGM based 3D printing experimental device.
