Friends who know about 3D printers know that the consumables used in general FDM 3D printers are linear materials. The average price is about 40 to 50 rolls. So, what happens if the consumables used by 3D printers are no longer linear materials, but can directly use standard thermoplastic granular materials?


At present, the wires used in the existing FDM 3D printers, such as ABS, PLA, or PETG, all use pellet raw materials, and the pellets are converted into wires through wire drawing equipment. This step determines that the molded wire is much more expensive than the raw material. Once a 3D printer can directly use granular raw materials as consumables for direct printing, this will undoubtedly greatly reduce the cost of materials required for printing.


Of course, the advantages of pellet 3D printers are not only reflected in the cost of consumables. As long as they are thermoplastic plastic materials, even carbon brazing, composite metals, composite ceramics, etc., as long as they can be extruded through a hot melt nozzle, pellets can be used. Printing with 3D printers greatly expands the range of available materials and the scope of application of the equipment. At the same time, due to the different designs of the extrusion nozzles, the efficiency of printing and forming is much more efficient than FDM 3D printers. At present, the domestic brands that can independently research and develop pellet 3D printers include Shenzhen’s Creative 3D and Shanghai’s Kuying.


So, what kind of objects can be made by such a 3D printer or what fields can it be applied to? Here is a brief introduction. According to the materials used, the application fields of granular 3D printers are: prototype mold industry, furniture design industry, automobile Parts manufacturing industry, rehearsal building mold industry, portrait sculpture industry, medical brace industry, visual art industry, etc.



It can be seen that in the future, as the technology of granular 3D printers becomes more and more mature, with higher precision, and more and more common applications in the industry, granular 3D printers will replace traditional FDM 3D printers and will be mainly used in various industrial manufacturing.
