Fused Deposition Modeling (FDM)
FDM was developed by Stratasys. In this process, a plastic or wax material is extruded through a nozzle that traces the part´s cross sectional geometry layer by layer.
FDM has become a widely used additive fabrication technologies. A plastic filament is unwound from a coil and supplies material to an extrusion nozzle. The nozzle is heated to melt the plastic and has a mechanism which allows the flow of the melted plastic to be turned on and off. The nozzle is mounted to a mechanical stage which can be moved in both horizontal and vertical directions. As the nozzle is moved over the table in the required geometry, it deposits a then bead of extruded plastic to form each layer. the plastic cools and hardens immediately after being squirted from the nozzle and bonds to the layer below.
Abbreviation: FDM
Material type: Solid (Filaments)
Materials: ABS, Polycarbonate, Polyphenylsulfonite; Elastomers
Min layer thickness: 0,15 mm
Surface finish: Rough
Build speed: Slow
Applications: Form/fit testing, Functional testing, Small detailed parts, Presentation models…
