The 4th Asian 3D Printing Exhibition concluded on October 15th in Zhuhai. As a well-known exhibition in the industry, this exhibition attracted over 13000 professional buyers from over 86 countries to participate. However, compared to previous years, there has been a slight decrease in 3D exhibitors this year, and buyer feedback has also been relatively calm. It is understood that this year there are more than 50 exhibitors with an exhibition area of 5000 square meters, while last year there were 68 exhibitors with an exhibition area of around 5000 square meters. This means that the number of exhibitors has decreased, while the exhibition area has increased. There is actually a way to reduce this. At the beginning of the rise of the 3D craze, many companies began to flock to the 3D field. Over the past three years, with the survival of the fittest in the market, especially the research and protection of 3D printing patents, high-quality 3D producers have begun to establish themselves a

The lightweighting of automobiles is the top priority for future energy conservation and emission reduction work, therefore, there is a trend of plasticization of automobiles in the global automotive manufacturing industry. With the trend of automotive plasticization taking shape, the application and promotion of automotive plastic parts are expected to accelerate, and the entire industry will usher in rapid development with broad prospects. According to calculations, a car's weight can be reduced by 10%, resulting in a corresponding reduction of 6% to 8% in fuel consumption and a reduction of 5% to 6% in carbon dioxide emissions. So, in energy conservation and emission reduction, vehicle lightweighting is an indisputable hot topic. In this context, plastic materials with low density have become an effective way to reduce the weight of vehicle bodies. Among car parts of the same size, plastic products can generally reduce weight by 30% to 40% compared to steel, and have a significant l

In the field of 3D printing, 3D printing materials play a crucial role in 3D printers, and the emergence of finished products is approximately equivalent to the ordered stacking of 3D printing materials. The importance of 3D printing materials to 3D printers is similar to the importance of blood to the human body. 3D printing materials promote or restrict the development of 3D printing technology. At present, there are more than 200 types of 3D printing materials in total, and materials are born every once in a while. However, for the development of 3D printing, these materials are far from enough. The types of 3D printing materials vary depending on the 3D printing molding technology. 3D printing consumables are a type of 3D printing material mainly used in FDM models, which are also models with melt layer deposition technology. Due to extrusion molding, the material used to make this model needs to be made into linear consumables. These linear consumables

1¡¢ Problem analysis: During the injection molding process of nylon material, there may sometimes be a phenomenon of surface dullness. This phenomenon may lead to poor appearance of plastic parts, affect product quality, and also create a negative impression on customers. So, what is the reason for the lack of gloss on the surface of nylon injection molding? Firstly, it may be due to improper injection molding process parameters. For example, unreasonable settings of parameters such as mold temperature, melt temperature, and holding time can have an impact on the gloss of the surface of nylon injection molding. Secondly, during the injection molding process, the surface may lack luster due to factors such as fast or slow filling speed, uneven filling, and inconsistent crystallization. Finally, it is also possible that the failure to perform surface treatment after injection molding, such as surface polishing, painting, etc
