Additive manufacturing 
4.3 Other materials
Other types of material can be used in AM – ceramic materials, biological materials, microscale materials, electronics and MEMS (microelectromechanical systems). The actual techniques do not differ much from those for polymers and metals, but they are applied in slightly different ways.
These other techniques do not open up any significant issues. The main point is for you to appreciate the breadth of applications AM can be applied to.
