3D printing technology appeared in the mid-1990s, and is actually the latest rapid prototyping device using light curing and paper lamination technologies. It works basically the same as ordinary printing. The printer contains liquid or powder "printing materials". After connecting to the computer, the "printing materials" are superimposed layer by layer under computer control, and finally the blueprint on the computer is turned into a physical object. This printing technology is called 3D stereo printing technology.
The forming principle of 3D printing technology is basically layer by layer. No matter its forming principle is subdivided into many types, the most basic principle is roughly the same. The rapid development of 3D printing technology actually relies on the continuous innovation and development of 3D printing materials to adapt to a wider range of industry applications.
At present, 3D printing non-metallic polymer materials have been promoted to all levels of various industries, from the aerospace field to primary and secondary education, has been very popular. At present, there are also doubts about 3D printing technology. Some people questioned that 3D printing has only been very popular in recent years, but it has no substantial use value. It can only print the models used for display and does not have the mechanical properties or requirements to meet the requirements. In short, other performance can only be seen but not used.
With the continuous development of 3D printing consumable technology, 3D printing consumable manufacturers add carbon fiber with excellent mechanical properties to the fiber to achieve the purpose of improving the mechanical performance of 3D printing consumables. Carbon fiber is a high-strength, high-modulus fiber with a carbon content of more than 90%. It has the characteristics of high temperature resistance, friction resistance, electrical conductivity, thermal conductivity and corrosion resistance. The shape is fibrous, soft and can be processed into various fabrics. Due to the preferred orientation of the graphite crystallite structure along the fiber axis, there is a high Strength and modulus. The density of carbon fiber is small, so the specific strength and specific modulus are high. The main purpose of carbon fiber is to be used as a reinforcing material to compound with resin, metal, ceramics and carbon to manufacture advanced composite materials. Carbon fiber reinforced epoxy resin composite materials have the highest specific strength and specific modulus among existing engineering materials. The test proves that the parts printed using 3D printed carbon fiber consumables are about 10 times stronger than the parts printed using traditional thermoplastic materials 3D. To a certain extent, it can even replace metal-processed parts.
Carbon fiber materials provide more possibilities for 3D printing technology in manufacturing applications. Adding carbon fiber to 3D printing consumables can effectively improve the tensile strength, wear resistance, and high temperature resistance of consumables. Because carbon fiber has higher specific strength, it also reduces the weight of 3D printing models. Has broad application prospects.
