4 Materials and techniques

AM is a rapidly changing field of manufacturing. The current state-of-the-art for AM is unlikely to be the standard in the future. Therefore, in this section, only the fundamentals of certain specific techniques will be discussed.

As a general rule, AM systems can be divided into three categories based on the materials they are designed to use:

  • polymer materials
  • metallic materials
  • ceramic, biological and functional materials.
