| Recently, industrial 3D printer maker ExOne announced a partnership with SGL SGL, a leading manufacturer of carbon fiber products and materials, to apply its adhesive inkjet technology to 3D printed carbon and graphite parts under the co-branded CARBOPRINT .  SGL's carbon expertise, combined with ExOne's 3D printing technology, enables the CARBOPRINT line of products to be used quickly and economically to produce both prototype and low volume products for high temperature and mechanical applications such as chemicals, glass and metals. After printing the carbon objects are porous, so after the completion of these components, silicon or metal infiltration and polymer impregnation post-processing methods is very important.This can be adjusted according to the specific application of different material properties. There are four CARBOPRINT materials: CARBOPRINT C - carbon and graphite, low density and open porosity; CARBOPRINT M - Metallic carbon composite with good electrical and thermal conductivity CARBOPRINT P - Polymer Carbon Composites, accelerated development and good glide CARBOPRINT Si - Silicon carbide ceramic composites with high hardness and high temperature resistance Most carbon components are manufactured through traditional subtractive manufacturing processes, but there are many benefits to printing such materials through 3D, such as the possibility of intelligent functions such as heating and thermal management; manufacturing components will be filled with specific properties of graphite and carbon such as mechanical Strength, light weight, electrical and thermal conductivity, and low thermal expansion. In addition, users of adhesive injection technology can manufacture large industrial components and make complex designs for free. Due to the basic characteristics of carbon such as electrical conductivity and thermal conductivity and high chemical stability, the first batch of SGL and ExOne 3D printing test components, such as siliconized 3D printed carbon pump components and distillation column heat exchangers, are currently being developed for testing high Environmental technology and chemical equipment in the field of science and technology.
