Description
Thermoplastic feedstock used by fused deposition 3D printers to create a finished product. 3D printing filaments are available in a multitude of compositions and colors. Pigments or other additives are added to the material before it is melted to create colored filament or filament with special properties, e.g. increased strength or magnetic properties.
The process of transforming 3D printing filament into a 3D model
- The filament is fed into the FDM 3D printer.
- The thermoplastic is heated past its glass transition temperature inside the hotend.
- The filament is extruded and deposited by an extrusion head onto a build platform where it cools.
- The process is continuous, building up layers to create the model.
