Indian Engineering student makes Micro Jet Engine using 3D Printing.

3D Printing has emerged by 500% in last 3 years and is changing people’s live everyday. Another great work using 3D printing is done by an Indian engineering student,who built Micro Jet Engine which produces 20kg thrust and also can be used as electricity generator turbine. It all started as a college project at first but now it has future potential to be used as an electricity generator.He combined the 3d printing process and investment casting process to make the Jet Engine Rotating at 100000 RPM ! When he first saw the jetcat turbines on the internet it was only when he saw the price of around $12000 that he realised how inaccessible the technology truly was.Using 3D Printing and working with 3D OnSpot, he designed and built a Micro Jet Engine which actually produces thrust. The dream started when he wanted to fly like iron man and he found creating the micro thrusters was the only possibility to make it happen. So he decided to design and fabricate it himself.The first thing to be done was to design it in any 3d modelling software then run the analyses on different parts of the jet engine. With the help of youtube he learned to use the softwares required for designing and analyses part and also took some help from his teachers regarding the use of softwares. After this , he made some components using conventional machining methods but main problem was to create the turbine wheel and nozzle guide vanes as these cannot be made with conventional machining methods or if so, then the cost would get extremely high for these two parts only but this didnt stop him, he contacted various manufacturing units for making these parts but they agreed only on one condition that they could only make it in bulk (above 1000 pieces).Only then he decided to make those parts himself with the same accuracy. Then he discovered a way by struggling online for hours. Then he came to know that with 3D Printing its possible . Thats how parts were made using 3D Printing. So first he 3d printed the components in plastic then he applied technique of lost wax casting in his college’s furnace and used the 3d printed part as a mould in casting process and casted single piece of turbine and nozzle guide vanes with high accuracy.FDM Technology was used and the parts were printed in PLA material ,good part is both are easily accessible and have low cost. It could take no less than Rs.30000 ($434)per part if made using conventional methods but with 3d printing and www.3donspot.com it was possible with merely Rs.2500 ($37)(BOTH PARTS).Thats the Magic of 3d printing.
