Principle Of FDM Rapid Prototyping

Melt product forming (FDM--Fused Deposition Modeling) method, the method using filamentous material (paraffin, and metal, and plastic, and low melting point alloy silk) for raw materials, using electric heating way will silk material heating to is slightly higher than melting temperature (about than melting point high 1 ℃), in computer of control Xia, nozzle for x-y plane movement, will melting of material coated covered in work stage, cooling Hou formed artifacts of a layer section, a layer forming Hou, nozzle Shang moved a layer height, for Xia a layer coated covered, This layer-by-layer stacked to form three dimensional work pieces. Pollution of the method, the material can be recycled and used in forming of small workpieces. Below is the FDM schematic.

Material: solid filiform engineering plastics

Product performance: the equivalent of plastic or wax;

Main applications: plastic, cast wax models, prototypes or models.
