Based on the principle of additive manufacturing, 3D printing technology can quickly and efficiently obtain products by connecting a computer to a 3D printer. Fused deposition 3D printing technology (FDM) is the most popular 3D printing technology at present. It is widely used because of its low equipment cost and material cost. However, this technology still has some disadvantages, such as high material cost, slow printing speed and unsuitable high-temperature materials.

Granular melting 3D printing uses standard plastic particles to extrude molten materials through vertical spiral rod rotation heating. Multiple nozzles can be configured to work together. The molding size can be customized, and 30 kg of materials can be printed per hour. ABS, PP, nylon, TPU and other standard materials can be used, fiber or copper powder can be added to form composite materials, and biodegradable materials and recycled materials can also be used. It can meet the final use requirements of large-scale sculptures, buildings, doors and windows and other large parts.


Melt deposition process is the most widely used additive manufacturing technology in 3D printing industry. The traditional melting deposition process is to heat and melt the filamentous hot-melt material, and then extrude it through the micro nozzle. Due to the limited efficiency of resistance heating, the flow of extruded material is very low, generally less than 0.1cm3/s, which reduces the forming efficiency and forming speed, making this rapid prototyping technology not suitable for the establishment of large and medium-sized parts; On the other hand, the use of thermoplastic wires as raw materials limits the types of materials that can be used. It is not suitable for some plastics that are not easy to form wires or are hard and not easy to curl at room temperature.


In view of these defects, the manufacturer has developed a new type of particle melting printer. The 3D printer adopts a screw extruder with particle feeding, which can solve the problems of low molding efficiency and slow molding speed of the 3D printer for melt deposition molding. Moreover, the printing materials are not only limited to hot-melt materials, which greatly broadens the application range of the industry.

The emergence of particle melting 3D printing marks that the 3D printing industry has entered a new stage. It has brought fresh nutrients to the industry and broadened the business scope. We believe there are more surprises waiting for us to discover and experience. For more information about 3D printing, please search and pay attention to yunshang Zhizao.
