| Abstract Scope |
The present work focuses on enhancing mechanical strength characteristics of components that are fabricated through additive manufacturing process of vat polymerization. In this process a thin layers of photosensitive polymer resins are cured selectively solidified through precisely controlled laser beam movement. The tensile and impact strengths of photopolymer resins typically lie in ranges of 25-30 MPa and 12–15 J/m respectively that severely restricts the scope of applications of vat polymerized parts in serious engineering applications. The aforementioned problem is tackled through deposition of thin metallic foils of copper and nickel (20-30 μm) on polymer substrates leading to novel composites with discernible improvement in Mechanical and wear characteristics. Depositing thin metallic layers on photopolymer parts that are intrinsically non-conducting besides high smooth surface finish that deters the bonding. The innovation of the project lies in its approach to use IOT compliant 3D printers for manufacturing airfoil blades for rotary drone applications. |
