How to clean a hot clog in the head of an FDM type 3D printer
Residues are inevitable for FDM 3D printers for several reasons: small amounts of plastic are scorched by the overheated hot end, causing them to accumulate inside the nozzle; contamination from foreign bodies inside the wire after it has been produced; dust that has fallen on the surface of the wire reel is scorched and accumulates; trash is accidentally discarded into the hot end, etc. As a result FDM 3D printers often suffer from under-extrusion: for no apparent reason, but the extruder is unable to extrude enough material. If the extruder is pushing the wire at this time and the reel...
Common processes: MJF (multi jet fusion), npj (nano particle jet) Description: this technique uses inkjet to selectively drop an adhesive onto a flat powder bed. The area receiving the droplets will be solidified and the remaining powder will remain loose. Perform the above steps layer by layer until the entire object is generated. This process can be used to treat metals, sand, ceramics and other materials. Since the metal adhesive sprayer operates at room temperature, it will not warp and does not need support. Therefore, the adhesive ejector can be much larger than the powder bed fusion machine, and can...
How big is the difference between industrial grade 3d printers and desktop grade 3d printing?
Most desktop-level 3D printers on the market today are based on fused deposition (FDM) technology. They are similar to high-end industrial grade 3D printers in terms of molding principles, as they are both based on material extrusion and layer-by-layer deposition of molten thermoplastics through nozzles, but they have different capabilities. This article will discuss the main differences between desktop and industrial grade FDM 3D printers. What is the difference between industrial grade 3d printers and desktop grade 3d printing? Printing accuracy Typically, geometric tolerances and part accuracy depend on 3D printer calibration and model complexity. Industrial grade 3d printers produce...

Now many customers will find manufacturers of customized tablets on the Internet. In fact, this is also a good way. Because of the development of the Internet, many manufacturers will do some publicity on the Internet. However, in order to identify the strength of the manufacturer, it is still necessary to have a pair of hot eyes and be able to judge which manufacturer is the real one. Not just superficial propaganda. Today we will give you some suggestions to help you in choosing a prototype factory. The first strong manufacturer must have advanced production equipment. Only good equipment can...
The petrol and diesel engines of modern passenger cars are of all-aluminium design, with cost and weight optimisation using the latest conventional production techniques. The weight-to-power ratio of these engines has increased progressively in recent years, with mass-to-power ratios of around 1.1 kg/kw for 3- and 4-cylinder engines, reflecting the balance between material properties, load distribution and structural use of the engine for a given production boundary condition. This at the same time means that further significant weight reduction is not possible with conventional production techniques.In order to further investigate the potential for continued engine weight reduction in the context...

1.The influence of mold temperature on appearance: Firstly, the mold temperature is too low, which will reduce the melt fluidity and may cause underinjection. Mold temperature affects plastic crystallinity, for ABS, mold temperature is too low, the product finish is low. Compared with fillers, plastics migrate more easily to the surface when the temperature is high. So when the temperature of the injection mold is high, the plastic composition is closer to the surface of the injection mold, the filling will be better, and the brightness and luster will be higher. But the injection mold temperature can not be too...

Do you know anything about metal die casting? What is metal die casting?
Die casting is a metal casting process characterized by the application of high pressure to melted metal using an inner cavity of the mold. Molds are usually made from stronger alloys in a process similar to injection molding. Most die casting castings are iron free, such as zinc, copper, aluminum, magnesium, lead, tin and lead-tin alloys and their alloys. Depending on the type of die casting, cold chamber die casting machine or hot chamber die casting machine is needed. The cost of casting equipment and molds is high, so the die casting process is generally only used to manufacture large...

Die casting is the most commonly used casting technology in the casting industry. There are various problems in die casting. These are the ten common problems in die casting: 1.Hammerhead Stuck In order to avoid the hammer head stuck, you can start from two aspects: 1. In production, the temperature is often measured to avoid the hammer head and cylinder temperature is too high to cause the hammer head stuck; 2. The use of materials should choose high-quality alloy materials to avoid the infiltration of impurities. When putting back materials, attention should also be paid to not letting impurities mix,...

The latest technology, industrial status and industrial development of die casting die
Die casting die is a tool for casting metal parts, a tool for completing the die casting process in a special die casting die forging machine. The basic process of die casting is: the liquid metal is filled into the cavity of the mold at low speed or high speed. The mold has an active cavity surface. It is forged under pressure with the cooling process of the liquid metal, which not only eliminates the shrinkage cavity and porosity defects of the blank, but also makes the internal organization of the blank reach the broken grain of the forged state....
