This article specially is a brief introduction for currently 3D printing sheets features in different materials. With high speed developments and high demands of 3D printing industry, there are many home-made 3D printing machine devices for common people to use by just developing a special designed file through software, which is wonderful progress for human technology to make your idea into reality.

With the development of communication technology, mobile 5G signals are likely to be commercialized in early 2020. At that time, 5G smartphones will also develop towards thinness and portability, and the transmission speed of signals will become faster and faster. To truly unleash the perfect performance of 5G signals, one cannot do without the good performance of a mobile phone. So, what kind of mobile hardware can meet the demand for 5G signals?

Recently, the construction of the Sandu section of the Dafan Erduguan highway major and medium-sized repair project in Shangrao, Jiangxi Province began. For the first time in this major overhaul construction, domestically produced high viscosity and high elasticity modified plastic asphalt mixture has been applied. This new type of pavement material will be comprehensively promoted in the major overhaul project of the second line of provincial roads.

At present, the world‘s major engineering plastic producers include Bayer, BASF, DuPont, GE Plastics, and Ticona. The pattern of the engineering plastic industry is that industry giants occupy more than half of the market share. Taking the most representative nylon as an example, the top four nylon producers in the world are Dow Chemical Company (accounting for 24.4% of the global market share), BASF Company (accounting for 13.8%), General Electric Company (formerly G E/Honeywell Company has been acquired) (accounting for 12.5%), and Rodia Company (accounting for 9.1%), with other companies accounting for a total market share of 40.2%. Moreover, the aforementioned companies are still making additional investments to meet the future growth needs of the engineering plastic market....

The application of plastic, rubber, and fiber-reinforced composite materials in high-speed railway system engineering is very extensive. Currently, they are mainly used in railway lines and tracks, vehicle bodies and heads, electrical components, and bogies. The main components of the application and the main polymer and composite materials used are shown in the table below:

ABS engineering plastic, also known as PC+ABS (engineering plastic alloy), is called plastic alloy in Chinese in the chemical industry. It is named PC+ABS because this material not only has the excellent heat and weather resistance, dimensional stability, and impact resistance of PC resin, but also has the excellent processing flowability of ABS resin. At the same time, it has excellent impact strength, electrical performance, wear resistance, chemical resistance, dyeing properties, as well as good molding and mechanical processing....

Designed properly, all entering solid polymer fragments and certain types of PE gels entering the Maddock mixer can be trapped and dispersed into the matrix resin. But many are not properly designed. Here’s what to look out for.
