What material is used for 3d printing experiments? What effect does it have on the precision and strength of parts in the molding process

Print Pai professional for you to answer: 3D printing materials is the important material basis for the development of 3D printing technology, at present, 3D printing materials mainly include engineering plastics, photosensitive resins, rubber materials, metal materials and ceramic materials, etc., in addition to the colorful gypsum materials, artificial bone powder, cell biological raw materials and sugar and other food materials are also used in the field of 3D printing. 3D printing used in the These raw materials are specially developed for 3D printing equipment and processes, and are differentiated from ordinary plastics, gypsum, resins, etc., which are generally in the form of powders, filaments, laminates, liquids, and so on.

Engineering plastics 3D printing materials

Engineering plastics refers to industrial plastics used as industrial parts or shell materials, is the strength, impact resistance, heat resistance, hardness and aging resistance are superior plastics. Engineering plastics is currently the most widely used class of 3D printing materials, common ABS materials, PC materials, nylon materials, etc..

Photosensitive resin 3D printing materials

Photosensitive resin ultraviolet rays (UV) resin, polymer monomers and prepolymers, which add light (ultraviolet) initiator (or known as photosensitizer). In a certain wavelength of ultraviolet light (2500-300nm) irradiation can immediately cause polymerization reaction to complete curing. Photosensitive resins are generally liquid and can be used to make high-strength, high-temperature resistant, waterproof materials.

Rubber 3D Printing Materials

Rubber materials have the characteristics of many levels of elasticity, and the hardness, elongation at break, tear strength, and tensile strength of these materials make them ideally suited for applications requiring non-slip or soft surfaces.3D printed rubber products are mainly used in consumer electronics, medical devices, as well as automotive interiors, tires, and gaskets. .

Metal 3D printing materials

In recent years, 3D printing technology has been gradually applied to the manufacture of actual products, in which the 3D printing technology of metal materials has developed particularly rapidly. In the field of defense, Europe and the United States developed countries attach great importance to the development of 3D printing technology, at the expense of investing huge sums of money to research, and 3D printing metal parts has been the focus of research and application. At present, the application of metal powder materials used in 3D printing are mainly titanium alloy, cobalt-chromium alloy, stainless steel and aluminum alloy materials, etc., in addition to gold, silver and other precious metal powder materials used for printing jewelry.

Ceramic 3D printing materials

Ceramic materials have high strength, high hardness, high temperature resistance, low density, good chemical stability, corrosion resistance and other excellent characteristics, in the aerospace, automotive, biological and other industries have a wide range of applications. However, due to the hard and brittle characteristics of ceramic materials make its processing and forming particularly difficult, especially complex ceramic parts need to be formed through the mold. Mold processing costs are high, the development cycle is long, it is difficult to meet the demand for continuous updating of products.

Other 3D printing materials

In addition to the above introduction of 3D printing materials, currently used in color gypsum materials, artificial bone powder, cell biological raw materials and sugar and other materials. Colored gypsum material is a full-color 3D printing material that is gypsum-based, fragile, strong, and clear-colored.
