Influence of Technological Parameters on the Dimension of GEAR Parts Generated with PLA Matherial by FDM 3D Printing

Abstract

The purpose of this research is to establish the technology of 3D printable production on the principle of FDM of gears made of PLA, ABS and PETG mainly. In the paper we present first the dimensional generation and specific aspects that need to be considered to produce gears with internal or external teeth of the cylindrical type with vertical or inclined teeth. Generating the gears appeared as a necessity for the reconditioning of the components of the processing machines and of the electric machines made both in the process of elaboration of the bachelor�s and the laboratory works, with reduced energy resource consumption and low pollution as low as possible. After the construction, we past to identify the dimension that have implications for both mechanical and kinematic resistance to achieve a product with good cinematic and functional characteristics. After that are made an analysis of the layers generated, both from the computer simulation and from the point of view of the analysis of layers physically generated on a gear tooth with external teeth.

Comparative study regarding the wear of gearwheels manufactured through additive technologies

“…Among these, Farstad et al [4] investigate the friction of thermoplastic gearwheels. Vasilescu and Fleser [5] develop a research about the influence of some technological parameters on 3D printed gears. The authors of the article present a comparative study of the wear and contact pressure of gearwheels realized by additive technologies from different materials: PLA, ABS, PETG reinforced with carbon, nylon, keeping the module and the number of teeth constant [1][2][3].…”

Evaluation of the Mechanical Properties of the Samples Made by FDM 3D Printing

“…The evolution of this branch of rapid prototyping has been fast and inexpensive and it is still ongoing. The reason behind this phenomenon is the open-source nature of both the hardware and the software involved [1][2][3].…”

Experimental Study of Sintered Friction Material with Coconut Fiber for Brake Pads

“…Traditional materials used in automotive design have been studied over the time, so today is know their characteristics, their advantages and disadvantages. Technological issues that can not be adequately by using these materials have determined researchers in the field of automotives to look for new materials to replace the classic ones [3,4]. On the other side, due to the need for a sustainable resource of raw materials, as well as environmental problems, automotive manufacturers are always looking for new materials, especially composites, with law impact on the environment and human health.…”
