The FDM 3D printing technology (fused deposition modeling) was invented more than 25 years ago and has been continuously developed ever since.
It is an additive process technology that can be used to create extremely durable and durable components and assemblies made of plastic with low wall thicknesses and complex geometries quickly and easily. Depending on the requirements, high-quality thermoplastics such as ABS, PLA, ASA, etc. with different visual, chemical, thermal and mechanical properties are available.
At the beginning of the printing process, the 3D data stored in the STL file format is processed with the software belonging to the 3D printer. In this case, the object to be created is positioned in the installation space in the optimal location for the construction process and separated by the software into mathematically calculated layers (slicing). Thereafter, the tool paths and travel paths are automatically generated.
Required support structures for creating overhangs and complex geometries are automatically calculated, if necessary.
The edited, cut data is then transferred to the FDM 3D printer with all necessary parameters. In FDM-based 3D printing, the wire-shaped raw material wound on a material spool is pulled by wires into an X and Y movable machine head. Here, the material is melted, extruded through a fine nozzle and deposited layer by layer under high pressure on a building platform as a semi-liquid plastic strand. Depending on the 3D printer type, layer thicknesses between 0.127 and 0.330 mm are possible. After each completed layer, the build platform travels down the Z axis one layer at a time and the next layer is applied to the previous one. Finally, layer by layer, a solid, fully cured model is created.
