Process Parameter Variation and its Impact on the Mechanical Characteristics of 3D-Printed Structures

Abstract

Additive manufacturing is generally known as 3D printing, is capable in range of potential in the manufacturing industry. 3D printing was primarily developed in purpose of developing prototypes of experimental testing. But, recently 3D printing applications have increased in a widespread range. Although this has been a promising technology there are some drawbacks too. One of the main drawbacks in 3D printing is weaker mechanical properties of products when comparing with the products manufactured by conventional manufacturing methods. Since 3D printing has gained a new demand in manufacturing industry, there is a requirement of increasing the strength and durability of 3D printed products to an optimum level.
This paper work is analysis of mechanical properties of 3D printed objects by varying process parameters such as layer thickness and printing temperature. In the work two sets of specimens numbering each 1-6 were manufactured for both tensile and flexural testing. All the specimens were manufactured by varying their layer thicknesses through fused deposition modeling technique. Finally testing will doing on the specimens with the help of universal testing machine
