Design/methodology/approach: Specimens are manufactured in accordance with the standard specifications set for each test type. Subsequently, compression, tensile and shear tests are conducted in a laboratory setting. The resulting data are employed to ascertain the most illustrative properties of these materials, thereby facilitating a comparative analysis of their properties compared to the same materials without carbon fiber addition. Findings: The data illustrate a notable improvement in the modulus of CF materials in comparison to the same material without carbon fiber addition. In comparison to non-CF ASA filament, ASA CF material is shown to exhibit a 24% increase in compressive modulus and a 39% increase in modulus of elasticity. Furthermore, PETG CF demonstrated a 29% increase in compressive modulus compared to non-CF PETG filament, along with an increase of up to 193% in specific compression modulus. Additionally, the shear modulus of ASA CF is observed to increase by 56%. In contrast, PETG CF demonstrated a modest 14% increase in compression modulus. These results indicate the possibility of exploring innovative applications of filament deposition modeling (FDM) printing, where the enhanced attributes of these materials are essential. Originality/value: A thorough literature search revealed that previous studies has concentrated on the examination of materials such as polylactic acid (PLA) and acrylonitrile butadiene styrene (ABS), with minimal attention paid to other materials that are commonly utilized in FDM, including PETG and ASA. info:eu-repo/grantAgreement/ES/AEI/AEI PID2022-137134NB-I00 info:eu-repo/semantics/openAccess by-nc https://creativecommons.org/licenses/by-nc/4.0/deed.es info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Miralbes, Ramon Universidad de Zaragoza (orcid)0000-0002-9702-9314 Ranz, David Universidad de Zaragoza (orcid)0000-0001-8451-660X Gomez, Jose Antonio Universidad de Zaragoza (orcid)0000-0002-1548-3944 5002 305 Universidad de Zaragoza Dpto.
