Abstract

Additive manufacturing (AM) emerged from rapid prototyping to relinquish sustainable industrial production. The role of AM in the industrial field is to diminish manufacturing pace, functioning cost, and assembling the AM lightweight particles together, which enhances the malleable fabrication of personalized user defined components without symbolic concussion. The automotive manufacturing industry plays a chief role in the aggressive trade field where time to market declines. The engraving design structures with weight reduction materials are the demands faced by the automotive industry that can be ominously resolved by additive manufacturing technology. This research work provides a better understanding of AM technology and its role in automotive sector to enhance modern vehicle designs and enduring features and augments the knowledge of both researchers and industrialists to overcome the efficacy in manufacturing process by fabricating relatively high strength geometries with reduced weight.

Am In Automotive Industry

Additive Manufacturing Technique

The Additive manufacturing technologies familiarize many innovative and monetary gains when compared to conservative subtractive manufacturing methods in rapid prototyping (RP). The Additive Manufacturing (AM) technology is developed from the RP technology to enhance the quality of the output product. Additive Manufacturing acts as a basic principle of creating three dimensional (3D) objects generated through Computer Aided Design (CAD) systems. In AM technology, the components are made from CAD data and slicing software to create specified part geometry rather than complex tooling and additional fixtures that are used in conventional manufacturing methodologies (Costas et al. 2018). The structures are built in a layer-by-layer fashion with a specified cross section and which is not only used in manufacturing industries to fabricate automobile components and dynamic mechanical structures but also enlists its application in tissue engineering with the capacity of bioprinting to create biomedical implants, artificial human organs and drug delivery systems. The AM technology acts as a key for solving environmental and engineering issues since it has Free-Form Fabrication (FFF) that facilitates to produce user defined geometries with all classes of raw materials without any limitations unlike metals, non-metals, alloys, and synthetic polymers with no wastage of materials. The development of this technology improves with its increasing applications all over the engineering industry. Figure 1 explain the additive manufacturing technology.

Key Terms in this Chapter

Laser Metal Fusion: In this method a 3D part formed by selectively melting the powder from the power bed and fusing it in layers with their support structures.

Hybrid Manufacturing: The term “hybrid manufacturing” designates the process of combining additive manufacturing addition of materials in layers frame a component.

Selective Laser Melting: In this method the metallic powders are fused together using high density lasers.

Additive Manufacturing: It can be described as a “freedom fabrication” as it can construct any complex geometry with diverse materials by addition of elements in a layer by layer process.

Direct Metal Deposition: This method is not based on other types of powder bed, but it uses a feed nozzle to extrude the powder into the laser beam.

Direct Metal Laser Sintering: This technique is similar to selective laser melting but has greater efficiency on comparing with SLM technique.

Electron Beam Melting: A beam of electron is used to heat the raw material under vacuum and fused together.
