Jigs and fixtures are tools used in machine manufacturing. It is usually used to fix the workpiece in the proper position and guide the cutting tool. This is to enable the operator to minimize cutting errors and reduce injuries. One of the main advantages of clamps and fixtures is that it can help workers easily install or assemble parts under the guidance of the fixtures. This will greatly reduce time and errors. Generally, the materials used to make jigs and fixtures are steel or aluminum.With the use of particulate FGF 3D printers, the cost of manufacturing these tools has been greatly reduced. Designers can also let go of their thinking when designing more complex designs without being restricted by injection molding. Complex shapes such as contours and irregular models are no longer restricted by traditional methods.Many manufacturing companies have been committed to improving productivity and reducing costs. Lean production techniques and the implementation of inspection tools,...

The 3D printing technology is based on the principle of additive manufacturing, and the product can be obtained quickly and efficiently through a computer connected to a 3D printer. Melt structure forming technology (FGF for short) is a new type of 3D printing technology in the world. This technology is widely used due to the low cost of equipment and materials. Compared with FDM technology such as high material cost, slow printing speed and unsuitable high-temperature materials, FGF's material cost and printing speed have been improved, and it can adapt to different consumables.The pellet melting 3D printer uses standard plastic pellets to extrude the molten material through the rotation and heating of a vertical screw rod. It can be equipped with multiple nozzles to work together, and the molding size can be customized. It can print 30 kg of material per hour. Standard materials such as ABS, PP, nylon, and TPU can be used. Fiber or copper powder can also be added to form composite m...

Among various particle 3D printing technologies, FDM is currently the technology with the highest market share, and its technical products are found in all walks of life and personal hobbies. FDM technology uses hot-melt accumulation molding, that is, wire and particle materials are melted into a liquid state at high temperature, and then extruded to the printing platform through a hot-melt nozzle until it is formed. In the entire FDM3D printing, the hot melt nozzle is a very important part, so why is the hot melt nozzle in your FDM3D printer so important?In FDM3D printers, the printing accuracy is mainly determined by the caliber of the hot melt nozzle. At present, most of the hot melt nozzles on the market have a diameter of 0.1 to 2.0, and the consumables used are basically 1.75mm and 2.85mm. Then, if you are pursuing printing accuracy, choose a small-caliber hot melt nozzle, and if you need to print quickly, choose a large-caliber hot melt nozzle. If you need a smooth and flat pri...

What is particle 3D printing? Particle additive manufacturing or particle 3D printing, sometimes called fused particle manufacturing (FGF), is a variant of fused deposition modeling (FDM, or FFF for fused filament manufacturing), which uses particles as raw materials instead of Filament. Although filaments are suitable for most 3D printing applications, particle 3D printing has a place in prototyping and large format printing, which can provide important advantages such as lower costs and faster build speeds.However, to use pellets as a raw material, a special type of extruder different from that on FDM printers is required.Particle 3D printing draws on all aspects of plastic molding processes such as FDM and injection molding. Like FDM, it builds parts layer by layer by extruding molten material from nozzles connected to a computer-controlled print head. The difference between it and FDM is that it is more similar to injection molding, in that it feeds raw materials into the nozzle t...

We all know what 3D printers are used for, and after the explosion of 3D printing in various industries in 2016, many pioneers want to participate in this future technology market. Some have established companies that specialize in the development of 3D printing equipment, and some want to become agents to open up the local market. But no matter what it is, the future of 3D printing assets will become larger and larger. PioCreat's G5 pellet hot-melt 3D printer pellet hot-melt technology-G5 industrial-grade 3D printer.　　The best service of particle 3D printer service is prototype mould processing service. In practice, the earliest beginning of 3D printing in the manufacturing industry is to manufacture prototypes. The prototype is what we usually say, the sample used for testing before the product is officially finalized. Because when the conservative CNC manufacturing is manufacturing prototypes, some too complicated structures are difficult to manufacture, and the data and labor cost...

With the rapid development of the 3D printing industry, fused deposition technology (FGF, Fused Deposition Modeling) has developed into one of the most mature rapid prototyping processes. Among them, the FGF particle 3D printer linear particle plastic 3D printer relies on its high printing accuracy and flexible operation. Convenience and other advantages are widely used, but its further promotion is limited by the cost of consumables and the types of materials. This project innovatively uses engineering plastic particles as raw materials, and aims to develop FGF-type plastic particles 3D printer model, which has important research significance for reducing the cost of consumables and broadening the types of raw materials. This paper takes the screw-type plastic particle 3D printer as the research object, and solves its problems in feed jam, uneven filament output, poor printing stability and other aspects. Based on the DEM-CFD coupling model, first of all, the movement, force and dist...
