Additive Manufacturing (AM) describes technologies that build 3D objects by adding layer-upon-layer of material, whether the material is plastic, metal, concrete. Common to AM technologies is the use of computer, 3D modeling software (Computer Aided Design or CAD), machine equipment, and layering material. Once a CAD sketch is produced, the AM equipment reads in data from the CAD file, and lays downs or adds successive layers of liquid, powder, sheet material or other, in a layer-upon-layer fashion to fabricate a 3D object.

Aerospace has a long history of being an early adopter, innovator and investigator. What this industry was doing decades ago has now become commonplace. For example, the aerospace industry was the earliest adopter of carbon fiber, and it was the first to integrate CAD/CAM into its design process. There are many other examples that show that trends in aerospace are predictors of future trends in manufacturing across all industries.

The aerospace industry has incorporated additive manufacturing (AM) throughout all processes and functions; from the design concept to near-end-of-life repairs. With each success, it then drives AM deeper into related processes, making it multi-purpose. And aerospace continues to investigate new applications and invest in research to make them possible. Ultimately, the outcome of that research trickles down to AM users in a wide spectrum of disciplines and applications. As a design tool, AM, also known as 3D printing, has been in use for almost two decades. Aerospace lead the way, and all other industries will follows its footsteps, and thus aerospace has a trend-setting role in the industry.

There are more profitable opportunities of AM applications in aerospace industry. There are many segments where AM can be implemented in the aerospace industry supply chain and business activities.
