More and more users in electronic appliances, semiconductors, automobiles and other industries have begun to introduce 3D printing technology, and have carried out a series of technical reforms in new product development, functional testing, production jigs and small batch parts production. Most users prefer 3D printers based on FDM / FFF technology. They often have a special need for materials-anti-static.
The sudden current between two charged objects can cause damage to sensitive components such as electronic devices, affect magnetic media, and cause unstable operation or even damage to electronic and electrical products. To prevent this from happening, electrostatic discharge (ESD) safety materials are often used to protect sensitive components. ESD anti-static protection is effective for high-density, miniaturized and complex electronic devices. 3D printed parts need anti-static function.
Clariant's 3D printing business department has launched a series of ESD anti-static 3D printing materials that can meet the printing needs of electronic appliances. It uses unique carbon nanotube technology, advanced material performance improvement technology and precision extrusion process to meet the needs of different ESD materials. The surface resistivity of Clariant's full line of anti-static products reaches 10 ^ 6 to 10 ^ 10 Ω, providing ESD safety protection for sensitive electronic components.
The types of anti-static wires for FDM / FFF 3D printing technology include:
· Clariant anti-static PLA has excellent material properties and printability, avoids degradation and yellowing due to thermal oxidation, and has a good printing surface effect. It is suitable for printing anti-static components that do not require high material strength.
· Clariant anti-static PET-G has high mechanical strength and processing performance, is easy to print, and meets the needs of 3D printing jigs, fixtures and other components.
· Clariant anti-static PC ABS, with high toughness, high impact strength, high temperature resistance and high dimensional stability, is suitable for the housing of precision electronic and mechanical components working in harsh industrial environments.
Clariant anti-static carbon fiber reinforced nylon PA6 / 66 CF20, made of special nylon PA6 / 66 combined with long carbon fiber, is a high strength, high chemical resistance and high temperature (160 degrees) material. Clariant's special formula reduces warpage and improves printability. It is suitable for printing large-sized, high-strength parts.
· Clariant anti-static TPU has high tensile strength, excellent wear resistance and high fluidity, which can meet the needs of customers for flexible anti-static materials.
At present, many well-known enterprises in the world are using anti-static 3D printing materials, such as Foxconn, Jabil, Micron, Continental Automotive, etc., mainly used in the 3D printing of electronic product testing tools, production fixtures, maintenance tools. This kind of material with special properties has been really applied in the manufacturing process, which has benefited enterprises.
