Abstract

3D printing is manufacturing process that consists of the fabrication of prototypes, parts and functional pieces. Several methods can be used, with different materials in different formats. One of the most popular techniques is the Fused Deposition Modelling (FDM). This method has several advantages with respect to other manufacturing processes, although it also has some problems and difficulties. One of these problems arises when setting the printing parameters. Generally, the printing parameters are selected according to the user’s experience, although it is rather difficult to adapt the parameter settings in order to obtain specific mechanical properties of the printed parts.This work, analyzes the influence of infill on the tensile strength in parts printed with ABS, using a Makerbot Replicator 2X 3D printer. Test specimens were printed, modifying the infill, while maintaining the other parameters constant. Afterwards, the test specimens were tested in a traction test obtaining the tensile strength. In addition, the effective impression time was analyzed, in order to obtain a recommended infill ranges of impression time and tensile strength.Results showed that the maximum tensile strength was 34.57 [MPa] considering a 100% infill
