fused deposition modeling (FDM)

Fused Deposition Modeling (FDM) is a 3D printing technique for rapid prototyping. The printing technique, also known as the fused layer process, works with thermoplastic materials such as polycarbonate, which are applied in layers.

In the production of 3D models, the fusible plastic is heated by computer control in a fine nozzle and applied to the 3D model as a plastic filament. The nozzle function can be switched on and off, allowing the plastic thread, which is between 0.02 mm and 1 mm thin, to be applied partially. The plastic thread is used to apply the individual model layers in layers in the X and Y directions, whereby the newly applied layers bond with the existing ones. The material then hardens immediately. The resolution is between 25 µm and 1,250 µm.

The fused layer process is suitable for rapid model and prototype production. The FDM process was developed by Stratasys Inc. and the name is protected as a trademark.
