Rapid prototyping of bucket tooth fused deposition
1 .Principles of Technology
FDM-fuseddeposition modeling process is thermoplastic material hot melt, drycontact. In computer control layer by layer deposition process.
Materialfirst pumped into filamentous. Through the wire feeding mechanism forfeeding nozzle, in the spray nozzle is heated until the molten state.Nozzle along the cross-section parts round which and filling softtracks. At the same time, the molten material extrusion, material rapidsolidification. Wells and Zhou Tian materials dry. Layers stacked. Likeeventually made machine pre designed components.
2 .Process features and Applications
(1) FDM process without laser. The operation is simple and easy, and has no pollution to the environment.
(2)the forming process needs to be constructed, but the requiredsupporting components can be used in another nozzle to form anothermaterial, which is not easy to remove.
(3)the disadvantage of this process is that the structure is not easy tomanufacture complex parts. The precision of the forming parts is low,the surface quality of a difference t forming efficiency is low, whichis not suitable for the manufacture of large parts.
Fuseddeposition RP wins the materials used in forming mainly ABS plastic,stone clam, low melting point metal, rubber roll, Yi thermoplastic wire.
