Many people pay attention to 3D printing, first of all, attracted by the beautiful small objects printed by 3D. Further, some friends will care about the performance of different models of 3D printers, and 3D printing materials have been neglected in most cases. In fact, 3D printing materials can be said to be an important material basis for the development of 3D printing technology. The development of materials largely determines whether 3D printing can be used more widely.
At present, 3D printing materials mainly include polymer materials, metal materials, powder materials, ceramic materials and composite materials.
Polymer materials mainly include engineering plastics, bio-plastics, thermosetting plastics, photosensitive resins, etc., and the performance of different types of materials is quite different.
Engineering plastic refers to industrial plastic used as industrial parts or outer casing materials. It is a plastic with excellent strength, impact resistance, heat resistance, hardness and aging resistance. It is a kind of 3D printing material with a wide range of applications; bioplastics It mainly has PLA, PETG, PHB, etc., and has good biodegradability; thermosetting resin has high strength and fire resistance, and is very suitable for powder laser sintering forming process using 3D printing; photosensitive resin has faster curing speed, table Excellent dry performance, smooth appearance after molding, is the choice of many high-precision products printing.
Although most of the current 3D printing materials are plastics, the good mechanical strength and electrical conductivity of the metal have made researchers very interested in the printing of metal objects. The main metal materials include ferrous metals including stainless steel and superalloys, and non-ferrous metals such as titanium, magnesium alloy, and gallium.
It is neither a plastic material nor a metal material, but with its excellent adaptability to 3D printing technology, powder materials are still a good choice for 3D printing. 3D printing requires high powder materials, and the molding powder is required to have good material formability, high molding strength, small powder particle size, difficulty in agglomeration, good rolling property, suitable density and porosity, and fast drying and hardening. The first self-produced sprinkler sand type 3D printer developed by ASK Technology Co., Ltd. uses quartz sand in powder materials.
Aluminosilicate ceramic powder can be used in 3D printed ceramic products. The 3D printed ceramic product is impervious to water, heat (up to 600 ° C), recyclable, non-toxic, but its strength is not high, it can be used as an ideal cookware, tableware (cups, bowls, plates, egg cups and coasters) ) and home decoration materials such as candlesticks, tiles, vases, and artworks.
Undoubtedly, as the basis of 3D printing, 3D printing materials will become an important market for future 3D printing. More and more materials with excellent performance will be developed to promote the development of 3D printing industry. In addition, in addition to 3D printing materials, mastering the core technology and core components of 3D printing is also an important breakthrough in the development of the domestic 3D printing industry. The storm series 3D printer launched by ASK is the first inkjet printhead developed in China. (3D printing core components) is a milestone, and I hope that more companies in China can invest more energy in developing 3D printing core technology instead of relying entirely on foreign technology.
