Experimental study on the settings of Delta and Cartesian 3D printers for samples printing

This paper presents the first part of the experimental procedures developed at the beginning of a larger research, consisting of printing, on two 3D printers, one parallel and one cartesian, of some test specimens, in different working conditions and with different settings of some parameters, and then investigation of the tensile and compressive behavior of the test specimens. The research was carried out on two sets of standardized samples, printed with three types of the commonly used and low-cost material, Polylactic acid (PLA), Carbon fiber PLA (CF-PLA), and Polyethylene terephthalate glycol (PETG). The purpose of the study is to create a database with the results obtained, which will be a working basis for future printings with these printer models, available in our laboratory, in order to understand the 3D-printed material behavior under certain available working conditions.
