Engineering plastics are industrial plastics used as industrial parts or outer casing materials, and are plastics excellent in strength, impact resistance, heat resistance, hardness and aging resistance. Engineering plastics are currently the most widely used type of 3D printing materials. Commonly used are ABS, PC materials, PLA, nylon materials and so on.
2. Photosensitive resin
A photosensitive resin, an ultraviolet ray (UV) resin, consists of a polymer monomer and a prepolymer in which a light (ultraviolet light) initiator (or a photosensitizer) is added. Upon irradiation with a certain wavelength of ultraviolet light (2500 to 300 nm), the polymerization reaction can be immediately completed. Photosensitive resins are generally liquid and can be used to make high strength, high temperature resistant, and water repellent materials.
3. Rubber materials
Rubber-based materials are characterized by a variety of grades of elastomeric materials. The hardness, elongation at break, tear strength and tensile strength of these 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.
4. Metal materials
In recent years, 3D printing technology has been gradually applied to the manufacture of actual products, among which the 3D printing technology of metallic materials has developed particularly rapidly. In the field of national defense, developed countries in Europe and the United States attach great importance to the development of 3D printing technology, and they have invested heavily in research, and 3D printed metal parts have always been the focus of research and application. The metal powder used in 3D printing generally requires high purity, good sphericity, narrow particle size distribution, and low oxygen content. At present, metal powder materials used for 3D printing mainly include titanium alloys, cobalt-chromium alloys, stainless steels, and aluminum alloy materials, as well as precious metal powder materials such as gold and silver for printing jewelry.
5. Ceramic materials
Ceramic materials have excellent properties such as high strength, high hardness, high temperature resistance, low density, good chemical stability and corrosion resistance. They are widely used in aerospace, automotive, and biological industries. However, due to the hard and brittle nature of ceramic materials, it is particularly difficult to form and process, especially complex ceramic parts need to be formed by a mold. Mold processing costs are high and the development cycle is long, making it difficult to meet the needs of constantly updating products.
