3D Printing of Metal Matrix Composites

Abstract

In this day and age, additive manufacturing (AM) is playing a vital role in rapid tooling, rapid prototyping, and manufacturing. Additive manufacturing, also known as 3D printing, is recognized for its potential in sustainable design. 3D printing is used in producing complex geometries and personalized product attachments, among other applications. It can also be used to repair parts that are not readily available on the market. Pure polymer parts that are 3D printed have limited mechanical properties and also have limitations in functionalities. 3D printing exhibits many advantages in the production of composites, which also include high precision and cost-effectiveness along with other advantages. This chapter gives an overview of various techniques involved in 3D printing, like direct metal laser sintering, selective laser melting, electron beam melting, binder jetting, directed energy deposition, and laminated object manufacturing techniques for 3D printing of metal matrix composites (MMCs). The mechanical properties and performance of 3D-printed MMCs, along with the prospective applications, are also discussed in this chapter. Significant limitations are explored to encourage future research of the 3D printing of MMCs. In conclusion, in spite of many drawbacks, 3D printing may be able to deliver many advantages along with significant product life cycles.
