    How Does Additive Manufacturing Work?

What is Additive Manufacturing?

In additive manufacturing, material is applied layer by layer in precise geometric shapes based on a CAD model. In contrast, conventional manufacturing processes typically involve milling, carving or otherwise removing material to create an object. The terms 3D printing and additive manufacturing are often used synonymously. Strictly speaking, however, a distinction must be made: 3D printing is the more colloquial term. Additive manufacturing refers to the general manufacturing process - the production of objects by adding material - under which various production processes such as rapid prototyping, rapid tooling or mass customisation can be subsumed.

Benefits of Additive Manufacturing

Additive manufacturing can offer your company a significant competitive advantage. On-demand spare parts production directly on site reduces inventory and supply chain constraints. Lightweight designs mean less material, less energy, and less costs. Customisation and function integration enable a fast response to customer requirements.

We have been using EOS technology for more than eight years and have always had positive experiences. When used correctly, the design freedom provides significant benefits that give our customers market advantages that are nearly unrivalled.

Our Future Oriented Technology

At EOS, we work with the additive manufacturing technology of powder bed fusion. In this process, a CAD model is created, virtually cut into thin slices and converted into a file that the 3D printer can read. For the printing process, a thin layer of the desired powder material is applied to a building platform. A powerful laser beam then melts the powder in the exact locations specified by the computer model. A new layer of powder is applied and again fused with the underlying layer by laser. In this way, layer by layer, the finished product is created.

Cost Efficiency: Is Industrial Additive Manufacturing Worthwhile?

Industrial 3D printing can be a cost-effective alternative to traditional manufacturing processes in many areas. Key cost factors include:


Produce parts cost-efficiently, even in series production


Reduce the cost of producing and stocking spare parts by producing them locally on demand


Accelerate product development and prototyping to gain a competitive advantage


Completely new product development, beyond tooling or wax models

3D Printing Applications 

The original field of application for additive manufacturing was primarily rapid prototyping, with which product development and market launch could be significantly accelerated. In the meantime, however, industrial 3D printing has become an essential part of series production. EOS is one of the pioneers of this development.

Additive manufacturing is opening up new opportunities in demanding industries such as medical, automotive, mobility and aerospace, as well as in mass markets such as lifestyle and consumer goods, industrial and manufacturing. Additive manufacturing offers numerous competitive advantages and creates sustainable foundations for the future.
