What is FDM process? What are the advantages of traditional molding?

the advantages of p>fdm technology include the following six points:

1. Low cost. FDM technology does not use lasers, so the equipment operation and maintenance costs are low, and its molding materials are mostly engineering plastics such as ABS and PC, so the cost is also low. Therefore, at present, desktop 3D printers mostly use FDM technology.

2. The range of molding materials is wide. From the above analysis, we know that thermoplastic materials such as ABS, PLA, PC and PP can be used as the molding materials of FDM path, which are common engineering plastics, easy to obtain and low in cost.

3, less environmental pollution. The whole process only involves the melting and solidification of thermoplastic materials, and it is carried out in a relatively closed 3D printing room, and it does not involve high temperature and high pressure, and there is no discharge of toxic and harmful substances. Therefore, it is environmentally friendly.

4. The equipment and materials are small. The 3D printer equipment using FDM path is small in size, and the consumables are also rolled silk materials, which is convenient to carry and suitable for offices, families and other environments.

5. The utilization rate of raw materials is high. Unused or discarded molding materials and supporting materials can be recycled, processed and reused, which can effectively improve the utilization efficiency of raw materials.

6. Post-processing is relatively simple. At present, most of the supporting materials used are water-soluble materials, and peeling is relatively simple. However, other post-processing technologies often need curing treatment, which requires other auxiliary equipment, but FDM does not.
