3D PRINTING OF HOLLOW COMPOUNDS

Anil Kumar, Ravi Katukam

Abstract: 3D Printing is a process of manufacturing the product on the layer by layer. And it is best processes for producing a finished objects. It was started in 1980"s with the invention of stereo lithography. It has gone through various ups and downs throughout its development and rejection of new technologies. In this paper, we h3ave summarized the printing of hollow compounds with different shapes. Applications of 3D printed hollow compounds are turbine blades, gears, disc brakes etc. One of the major application of 3D printing is hollow turbine blade. A turbine blade is the individual components. These are used to up the turbine section of a gas turbine. The blades must designed to withstand the high pressure and high temperature comings from combustor. These 3D printed hollow compounds has same strength as solid compounds when compared. Major advantages of the Hollow shaped compounds are heat transfer, low material cost. The aim of the paper is to reduce the cost of material and easy manufacturing of hollow compounds compared to traditional process and taken hollow turbine blade as example.
