1. Introduction 1. Introduction

Additive Manufacturing (AM) which is commonly referred to three-dimensional (3D) printing presents unique capabilities compared to traditional manufacturing processes. Indeed, 3D printing allows creating geometrically com plex parts to answer specific requests in very short time and for a fixed cost. As 3D printing is an adaptable technique, manufacturing a number of di ff erent parts and their design iterations is less of an issue, making this technique a strong solution for evolving designs. Variety of materials utilized in 3D printing (e.g., thermoplastics, metals, and ceramics), fabrication of small series for a very a ff ordable cost, and the ability of 3D printing in optimizing existing tools should be considered as other benefits of 3D printing. Due to the above-mentioned capabilities, 3D printing has quickly captivated scientists and engineers from all disciplines.
