Designing components is a complex task, which depends on the component function, the raw material, and the production technology. In the case of rotating parts with higher RPM, the creep and orientation are essential material properties. The PLA components made with the material extrusion process are more resistant than VeroWhite (material jetting) and behave similarly to weakly cross-linked elastomers. Also, based on the tensile tests, Young’s modulus shows minimal anisotropy. Multilinear isotropic hardening and modified time hardening models are used to create the finite element model. Based on the measurements, the finite element method simulation was identified. The deformation in the compressor wheel during rotation became definable. It was concluded that the strain of the compressor wheel manufactured with material extrusion technology is not significant.
The potential of three-dimensional (3D) printing in polymer tribology is poorly explored. Material alignment and composition plays a vital role in altering the friction and wear characteristics of 3D printed materials. In the current study 3D patterns using fused deposition modeling are used to print advanced tribo-composites. Two different surface patterns (line and circular) are provided through 3D printing using white and silver Poly Lactic Acid (PLA). The deformation and the distribution of white and silver PLA over the samples surface are observed after the wear test. Results showed that the coefficient of friction is not being influenced by changing in the surface pattern. However, the wear rate increased for samples with line patterns on the contact surface, since the plastic flow was more significant in this case. Moreover, the filling factor exhibited an influence on increasing the plastic flow of the contact surface in case of the samples with line pattern.
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.
