There are many kinds of 3D printing materials. How much do you know?
Compared with traditional manufacturing technology, 3D printing does not need to make molds in advance, it does not have to remove a large amount of materials in the manufacturing process, and the final product can be obtained without complicated forging process. Therefore, structural optimization and material saving can be achieved in production. save energy.
Metal 3D printing is a technology of digital thermal processing. Currently, 3D printing technologies for metal preparation include: selective laser melting/sintering (SLM/SLS), electron beam selective melting (EBSM), laser near net forming (LENS), etc. .
ABS can be said to be the most commonly used printing material for FDM. Currently, it is available in a variety of colors. It is the favorite printing material for consumer 3D printer users, such as printing many toys of the "Lego" type, making a lot of creative home accessories.
Graphene, a honeycomb two-dimensional material formed by sp2 hybridization of carbon atoms, is considered to be a "magic material." The advantages of graphene itself are light weight, high strength and good electrical conductivity.
The hardness, elongation at break, tear strength and tensile strength of rubber-based materials make them ideal for applications requiring non-slip or soft surfaces. 3D printed rubber products mainly include consumer electronics, medical equipment, and automotive interiors, tires, gaskets, etc.
3D printing combines cutting-edge technologies in digital modeling technology, electromechanical control technology, information technology, materials science and chemistry, etc. It is a kind of rapid prototyping technology and is known as the core technology of the "third industrial revolution."
