3d printing and traditional technology

3d printing is a technology based on digital model files, which uses adhesive materials such as powder metal or plastic to construct objects by printing layer by layer. What are the specific advantages of 3d printing?

Advantages of 3d printing

First, the advantages of 3d printing

Manufacturing complex items will not increase the cost; Product diversification does not increase costs; No assembly is required; 3D printers can be print on demand; 3D printers need less operation skills than injection molding machines; In terms of unit production space, compared with traditional manufacturing machines, 3D printers have stronger manufacturing capabilities. Compared with traditional metal manufacturing technology, 3D printers produce fewer by-products when manufacturing metal.

Advantages of 3d printing

Second, the application field of 3d printing

3d printing technology has been applied in jewelry, footwear, industrial design, architecture, aerospace, dentistry and medical industry, education, geographic information system, civil engineering, guns and other fields. (1) Low-cost manufacturing of complex articles

As we all know, using traditional manufacturing methods, the more complex the shape and structure of processed goods, the higher the manufacturing cost will be. Therefore, in order to pursue the lowest input of production cost, manufacturers often produce standardized parts in batches through labor subdivision and standardized workflow, which is difficult to meet the diversified needs of customers. However, for 3D printing, the same processing principle is made by adding materials, and there is no need to process molds and mechanical equipment. Even products with complex shapes will not increase the production cost and labor demand too much. 3D printing can reduce the cycle and cost of sample trial production and small batch production, which is beneficial to the development of new products, personalized and luxury customized products industries.

(2) The product has short production cycle and high precision.

3D printing technology can optimize many complicated processes in traditional manufacturing and processing industries, and directly manufacture complex structures, so as to find the problems existing in product modeling and structural design as soon as possible, reduce the turnover and accumulated losses of other subsequent processes caused by frequent design changes, and significantly improve the efficiency of new product development and the success rate of putting into production lines. For example, 3D printing does not need mold opening process, which greatly saves operation time; The characteristics of one-step molding greatly reduce the workload of later auxiliary processing and outsourcing processing, and effectively ensure the security of confidential data in some confidential fields (such as aviation, nuclear power, military industry and other industries). At the same time, it also reduces the error accumulation in the post-processing process and makes the products more accurate, especially in high-end precision machinery industries such as automobiles, airplanes and nuclear power. 3D printing technology can realize the natural seamless connection of products, without parting lines and unnecessary gaps, which makes the product structure more stable, and the stiffness and strength are obviously higher than those of traditional manufacturing processes. Compared with traditional production technology, 3D printing technology can improve processing efficiency by 3.5 times and shorten product development cycle by 30%. Save the production cost by 30%. 50%.

(3) Variety and personalized design of product categories.

Traditional machinery and equipment are limited by their functions, and the types of products produced are also very limited. However, 3D printing technology does not need to buy new mechanical equipment or train new professional technicians. Countless products with different forms can be printed only by using the same 3D printer, and an assembly-free structure and a complex porous structure can be formed, which can not be realized by the traditional technology, thus realizing the personalized customization experience of users. The tense and awkward relationship between designers and products, designers and users, and users and products has been alleviated because of the emergence of 3D printing technology.

(4) Integrated molding and manufacturing of products

The traditional production of large-scale systems needs to produce different parts, and then be assembled and adjusted by workers or robots on the assembly line. The more parts, the greater the labor and time cost of product assembly. The most typical example is the manufacturing process of electronic circuits. First, people have to make the internal plastic and ceramic parts one by one through different mechanical equipment, and then assemble them to form the metal parts of electronic circuits. 3D printing can realize the integration of products.
