All 3D printing silk materials are made of thermoplastic granular materials. Why not skip the silk materials and directly use granular materials for 3D printing? This can save more material costs. In addition, can the pellet 3D printer be compatible with a variety of materials like the silk printer? Especially high-performance 3D printing materials.

In September 2021, piocreat3d launched a pellet 3D printer G12 with a length, width and height of 1200x1000x1000mm.

This equipment not only has a large printing format and can directly use granular materials, but also increases the extrusion temperature to 450 ℃, adopts a three-stage extrusion temperature control system and uses a closed insulation cavity, so that it can support most of the thermoplastic granular materials in the market, including peek, PC, PLA, PPSU and other high-performance materials.

G12 owns 1.2 × one × It has a molding size of 1m, built-in 25kg drying hopper, self-developed screw extrusion device and chamber temperature control design, and has the function of remote automatic feeding.

The G12 extruder can reach 450 ℃ at most, with the function of liquid cooling and heat dissipation, and the maximum throughput can reach 5kg / h. The modular design is adopted. Users can choose high-temperature extrusion head or universal temperature extrusion head and replace it quickly.

Thanks to the accumulation of material technology in piocreat3d online high temperature series printer and the production experience in 3D printing wire extruder, piocreat3d can quickly open up the upstream process resources and downstream applications of thermoplastic granular materials. At present, piocreat3d has carried out printing tests of dozens of raw materials of different brands.

The process of different materials needs a long time of exploration and testing, so that a relatively stable production process can be obtained. To this end, piocrat3d has set up its own printing technology department, equipped with a number of independent printers and testing instruments, and is committed to creating a perfect material system and molding process for the machine.

Compared with fuse manufacturing (FDM), granular 3D printing has higher efficiency and lower cost. Because it is closer to the traditional injection molding or extrusion process, the performance of granular printed parts is usually higher than that of silk printing.
However, the disadvantages of particle printing are also obvious. The large throughput makes its lamination very high and line width very large. The control of screw can not be as accurate as the advance and retreat of wire controlled by gear, resulting in serious back drawing. Therefore, the details of small parts can not be presented perfectly. The person in charge of piocreat3d said: "At present, granular 3D printing is such a manufacturing process with obvious advantages and disadvantages, which is very important to run in with the needs of end customers. In many application scenarios, piocrat3d began to gradually release the advantages and charm of granular printing, and there are mature schemes to solve the disadvantages, such as material mixing, fine post-processing, etc. at present, this type of model has been successfully launched, so you can further understand G40 .
