It has been suggested that 3d printer parts list pdf article be merged into fused filament fabrication. An ORDbot Quantum 3D printer.
It is one of the techniques used for 3D printing. Thus, FDM is also known as a solid-based AM technology. The technology was developed by S. Scott Crump in the late 1980s and was commercialized in 1990.
The term fused deposition modeling and its abbreviation to FDM are trademarked by Stratasys Inc. Scott Crump in the late 1980s and was commercialized in 1990 by Stratasys. DIY variants, which utilize this type of 3D printer.
This has led to two orders of magnitude price drop since this technology’s creation. If required, support structures may be generated. One may use one material to build up the model.
Use another as a soluble support structure. One could use multiple colors of the same type of thermoplastic on the same model. The model or part is produced by extruding small flattened strings of molten material to form layers as the material hardens immediately after extrusion from the nozzle. A plastic filament is unwound from a coil and supplies material to an extrusion nozzle which can turn the flow on and off.
There is typically an accurately controlled drive that pushes the filament into the nozzle. The nozzle is heated to melt the material. The thermoplastics are heated well past their glass transition temperature and are then deposited by an extrusion head.
The nozzle can be moved in both horizontal and vertical directions by a numerically controlled mechanism. Stepper motors or servo motors are typically employed to move the extrusion head. The mechanism used is often an X-Y-Z rectilinear design, although other mechanical designs such as deltabot have been employed. Although as a printing technology FDM is very flexible, and it is capable of dealing with small overhangs by the support from lower layers, FDM generally has some restrictions on the slope of the overhang, and cannot produce unsupported stalactites.
