With the development of 3d printing technology, more and more people realize its power, and even China lists it as part of the “Made in China 2025” plan. This shows how important China is to 3d printing technology, and thus embarked on a high speed. On the development train.
And we know that restricting the development of 3D printing is not only a technical problem, but also a problem of 3D printing materials, which restricts its development, but I believe that we will find corresponding 3D printing materials to make up for the development of 3D printers. Here are a few conventional 3d printing consumables.
Carbon fiber 3D printing material is modified on high-strength PLA/nylon, which basically contains fine carbon fiber. These West carbon fibers contain nozzle extrudates to increase the strength and hardness of consumables. And it also has a high melting point and viscosity, far exceeding PLA and ABS, has good size and stability, but the printing smell is very small.
Restrictions on use, this type of 3D printing consumables is suitable for tempered or hardened copper alloy nozzles. Carbon fiber reinforced materials can provide the strength equivalent to metals and are very light. They have broad application prospects in industries that need to consider the ratio of weight to strength, including aerospace and automotive.
PEEK is a semi-crystalline thermoplastic with high temperature resistance, self-lubricity, chemical stability, radiation resistance and electrical properties, as well as excellent mechanical properties. It is considered to be one of the best engineering thermoplastics in the world. PEEK can be used to manufacture demanding applications in the aerospace, automotive, oil and gas and medical industries.
In the field of biomedicine, polyetheretherketone has excellent biocompatibility. Compared with metal implants, its elastic modulus is closer to that of human bone. It can meet the normal physiological needs of the human body and is a good Of orthopedic implant materials.
PEEK can be used as a 3D printing material to manufacture mechanical parts and orthopedic implants, but because PEEK material has a higher melting point, most 3D printer nozzles are not able to better melt the PEEK material. This problem gives PEEK 3D printing, especially FDM 3D printing brings certain difficulties.
Nylon 3D printing consumables have the advantages of toughness and fatigue resistance, but they also have big defects. For example, durable prototypes with functionality must be printed in a fully enclosed 3D printer, which is more suitable for small batch production. It is widely used in highly fatigue resistant and reusable fitting fittings. Such as aerospace, automotive, fixtures, low-heat air intake components.
The metal printing material is made of PLA or abs metal powder. After high-processing processing, from the surface of the 3D printing material, it looks like it is made of copper and aluminum. These metal powder inks are similar to plastics, but more like metal.
Seeing here, do you feel that there is a lot of room for the development of 3D printing materials? Composite 3D printing consumables have become one of the drivers behind the mainstream technology and become one of the development aids for 3D printing technology. Moreover, the development direction of 3D printing consumables is toward the direction of hybrid materials. In the future, the model will pay more attention to strength and hardness, tend to be industrialized, and pay more attention to the use of 3D printing technology.
