Fused deposition modeling (FDM) or fused filament processing (FFF) belongs to the material extrusion series. In FDM, an object is constructed by selectively depositing molten material layer by layer in a predetermined path. The materials used are thermoplastic polymers, most of which are filamentous wires. Recently, granular equipment has also appeared.
FDM is the most widely used 3D printing technology, accounting for the largest proportion of the global 3D printing installed capacity, and is usually the first 3D printing device that people come into contact with. The nature of the FDM process itself determines the relatively rough accuracy of the printed product, and it is more used in areas such as consumption, education, and cultural creation in the initial stage. However, in recent years, with the rapid development of 3D printing technology, some quasi-industrial-grade FDM equipment, and industrial and medical-grade FDM printing materials have emerged, which has greatly broadened the application fields of FDM technology.
The Internet of Things system of Bering 3D can realize one-click printing of hundreds of FDM devices. A variety of materials and colors are available for selection. Whether it is a batch order or a large-size (acceptable splicing) sample, it can be delivered in a short time. Finish.
Fused Deposition Modeling (FDM) printing process
FDM process printing process
1. First, load a roll of thermoplastic filament into the printer. Once the nozzle reaches the required temperature, the filament is fed into the extrusion head and melted in the nozzle.
2. The extrusion head is connected to a 3-axis system so that it can move in the X and Y directions. The molten material is extruded into thin strips and deposited layer by layer in a predetermined position, where it cools and solidifies. Sometimes, the cooling rate of the material can be accelerated by using a cooling fan installed on the extrusion head.
3. After one layer is printed, the worktable drops the thickness of one layer in a predetermined increment along the Z axis. The material is extruded and deposited on the solidified material of the previous layer, and the material is stacked layer by layer to form the final product. .
4. After printing, remove the support and finish the surface
