Investigation on Flexural Property of Sandwich 3D Printed PLA Components - A Review

Abstract

Making a product from design to finished product is difficult and time consuming job in conventional manufacturing process but in additive manufacturing (AM) it is an easy process. In AM technologies Fused Deposition Modeling (FDM) is an important printing technology to produce components using thermos plastics. Up to date AM technologies are used to make parts in single material, by using this additive manufacturing sandwich parts can be fabricated to improve flexural property of the material. A lightweight core and two thin solid face sheets with strong flexural rigidity at the top and bottom make up sandwich constructions. Sandwich structures have a core that can be developed and updated to meet our needs, which offers up new possibilities in a variety of disciplines. This method can be done with a variety of filaments, PLA having properties such as biodegradability, lack of disagreeable odor when heated, and usual environmental compatibility throughout its life cycle. PLA also produces 10 times less potentially harmful ultra-fine particles than Acrylonitrile Butadiene Styrene. This article concentrated review on PLA and PLA composite materials to improve flexural property
