This paper presents a short part of a larger research and consists in the investigation of the compression behavior of samples printed on two 3D printers, one Delta and one Cartesian, from three types of the commonly used materials, Polylactic acid (PLA), Carbon fiber PLA (CF-PLA), and Polyethylene terephthalate glycol (PETG). After a specific introduction regarding the subject, the printing parameters used for printing the samples are exposed, in a table, followed by a paragraph on the compression testing, both with general and particular information, on this case. The research being under development, the first set of results obtained is presented, further tests and analysis following in order to realize a comprehensive characterization of the 3D printed materials’ behavior.
This paper exposes the initial part of a research consisting in the study of the tensile behavior of the 3D parts printed on two type of 3D printers, one Delta model FLSun QQ-S PRO and other one Cartesian model Tevo Tornado, by using three types of plastic materials, PLA, PLA-CF and PET-G. After a short introduction and a literature review on previous studies reffering to the subject, in the experimental section are exposed the printing parameters selected for printing the samples, toghether with the explanation of the testing procedure. The first set of results obtained is presented, consisting in the values achieved for two parameters, the load sustained by the test specimens at yield and at break, some graphic reprezentation of their variation, respectively a short interpretation of the results. Further tests and analysis will be developed in future work, in order to realize a comparative characterization of the 3D printed parts in function by the printers and materials used.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
