Abstract[edit]

It is challenging to 3-D print functional parts with known mechanical properties using variable open source 3-D printers. This study investigates the mechanical properties of 3-D printed parts using a commercial open-source 3-D printer for a wide range of materials. The samples are tested for tensile strength following ASTM D638. The results are presented and conclusions are drawn about the mechanical properties of various fused filament fabrication materials. The study demonstrates that the tensile strength of a 3-D printed specimen depends largely on the mass of the specimen, for all materials. Thus, to solve the challenge of unknown print quality a two step process is proposed, which has a reasonably high expectation that a part will have tensile strengths described in this study for a given material. First, the exterior of the print is inspected visually for sub-optimal layers. Then, to determine if there has been under-extrusion in the interior, the samples are massed. This mass is compared to what the theoretical value is using the densities provided in this study for the material and the volume of the object. This provides a means to assist low-cost open-source 3-D printers expand the range of object production to functional parts.
