Abstract

Turbojet drive or water jet as we know today that turbojet drive technology is a marine system that produces water jets for propulsion. However, the thing that must be considered is the thrust generated by the propeller because of a problem that is often discussed. The purpose of this study was to determinet the effect of variations of the turbo stator on the trust of the tubojet drive using the ST-PLA 3D printing material.in this study, the turbojet drive design method uses the concept of an outboard engine with the help of tools and hanging scales to get the value of the thrust so that it can be  analyzed later. This study compares 3 forms of turbo stator, namely 4 Blade, 6 Blade and 8 Blade, based on the results of this study it was found that the variation of the turbo stator has a major influence on the thrust of the turbojet drive with 3D printing product ST-PLA material. The test results show that the 8-blade turbo stator has the highest thrust with an average value of 44.145 N and the 4-blade turbo stator has the lowest thurst with an average value of 24.525 N. Besides, this data can also be used as a reference for development of a turbojet drive according to the desired speed with the selection of a turbo stator variation that has been tested.

Abstract

3D printing technology using the Fused Deposition Modeling (FDM) system is one of the manufacturing processes currently being developed. The rapid prototyping process makes it easier for academics in research. Acrylonitrile Butadiene Styrene (ABS) filament material is the type of material used in this research. The purpose of this study was to determine the effect of the use of the chamber on the 3D printing machine DIY (Do It Yourself) FDM type Cartesian ender model on the quality of product dimensional accuracy results. The method used in this research is experimental by using a chamber on a 3D printing machine and using process parameters. The results of the research by testing and measuring, it is found that the chamber affects the accuracy of the product dimensions with the heat bed temperature (80 ℃), nozzle temperature (230 ℃), print speed (40 mm/s), infill density (40%) and the use of layer thickness. (0.20 mm) shows a significant result of product dimensional accuracy.
