| Abstract Scope |
The multiaxial 3D printing process can reduce the manufacturing time, and open up the new way for the production of graded materials. It will also expand the application of sustainable additive manufacturing for repair and retrofit purposes.
In this study, the effect of counter-gravity deposition on the tensile interlayer fracture energy of extruded PLA material was investigated. The tensile samples with one-layer thickness were 3D printed at three orientations of 0º, 90º, and 180º with respect to the direction of gravity force. Also, the effect of the nozzle orifice diameter was assessed in conjunction with the deposition orientation. The ratio of nozzle orifice diameter to deposition height was 1 for all samples that were made with different nozzle diameters of 0.6 and 0.8 mm.
For both nozzle diameters, the statistical analysis of the interlayer fracture energies showed no significant difference for the samples that were 3D printed at different orientations. |
