Friends who know something about 3D printers know that the consumables used by general FDM 3D printers are linear materials. The average price is about ￥40 to ￥90 per roll. So what happens when the consumables used in 3D printers are no longer linear materials, but can directly use standard thermoplastic granular materials?

At present, the wire used in the existing fdm3d printer, such as ABS, PLA or PETG, uses granular raw materials to convert the particles into wire through wire drawing equipment. This step determines that the formed wire is much more expensive than the raw materials. Once the 3D printer can directly use granular raw materials as consumables for direct printing, it will undoubtedly greatly reduce the material cost required for printing.


Of course, the advantage of pellet 3D printer is not only reflected in the cost of consumables. As long as thermoplastic plastic materials, even carbon brazing dimension, composite metal and composite ceramics can be extruded through hot melting nozzle, granular 3D printer can be used for printing, which greatly expands the range of available materials and the application range of equipment. At the same time, due to the different design of extrusion nozzle, the efficiency of printing and forming is much more efficient than fdm3d printer. At present, the domestic brands that can independently develop granular 3D printers in China include chuangxiang Sandi in Shenzhen, and its granular 3D printer series products include G5, G12 and G40.

So, what objects can this kind of granular 3D printer make or what fields can it be applied to? In short, according to the different materials used, the application fields of granular 3D printer include: hand mold industry, furniture design industry, automobile parts manufacturing industry, rehearsal building mold industry, portrait sculpture industry, medical support industry, visual art industry, etc.

It can be seen that in the future, as the technology of granular 3D printer becomes more and more mature, the accuracy is higher and higher, and the industry is more and more widely used, granular 3D printer will replace the traditional fdm3d printer and will be mainly used in various industrial manufacturing industries.
