In addition to the above fields, 3D printing technology can also be applied to aerospace, energy, consumer electronics, finance and other fields. With the continuous development of technology, 3D printing models will play more roles, providing people with more support and convenience in various fields.
3D printing methods are classified into seven categories
The focus of the 3D printing model is to draw a single-layer printing line, use noise to create surface effects, copy and rotate multiple layers, and make unprinted parts of uniform size. The printing pen model uses a bridge to connect two parts. 3D printing is a rapid digital model file-based technology that uses special bonding materials such as wax, powdered metal, or plastic to build objects by layer-by-layer printing. . It is usually used for model making or direct manufacturing of some products in the fields of mold making, industrial design, etc., which means that this technology is becoming popular. Using a printer is like printing a letter: Hitting the on-screen “Print” button on a computer screen, a digital file is transferred to an inkjet printer, which sprays a layer of ink on the surface of the paper, creating a two-dimensional image. In 3D printing, software prints a series of digital slices through computer-aided design (CAD) and transfers the slice information to a 3D printer, which stacks successive thin layers until a solid object is formed. The difference between a 3D printer and a traditional printer is that the printer “ink” it uses is the real raw material.
What Is 3d printing, also known as additive manufacturing, is a technology that builds real three-dimensional objects by superimposing adhesive materials layer by layer based on digital model files. Compared with traditional manufacturing technology, 3D has other characteristics of printing technology “removing molds, reducing waste, and reducing inventory”. In production, it can optimize structure, save materials and energy, greatly improve manufacturing efficiency, and realize the innovative concept of “design-guided manufacturing”.
3D printing methods fall into seven categories:
- Advantages of material extrusion: low price of equipment and consumables, wide range of materials, high strength of printed products.
- Advantages of photopolymerization molding: high processing precision, smooth surface of printed products, and high overall exposure molding efficiency.
- Advantages of directed energy deposition: no support, high processing flexibility, and efficient preparation and repair of components can be realized.
- Advantages of material jetting type: it can realize high-precision full-color fast printing, and improve the aesthetic quality of prototypes and components.
- Advantages of binder jet molding: high molding efficiency, different colors can be printed in the same batch, and no support structure is required.
- Advantages of powder bed fusion molding: high precision, and can print metals (such as titanium, aluminum, copper, stainless steel, high-temperature alloys, etc.), ceramics, nylon and other materials.
- Advantages of lamination: fast forming speed, high precision, small warping deformation
How is the hand model factory industry developing?
The rapid prototype model industry gradually separated from the industrial design process and became a relatively independent industry and flourished. Many professional hand model companies have emerged, and large-scale enterprises and industrial design companies have also established their own hand model departments. The development of the hand model industry has gone through a difficult journey to this day. Since 1977, due to the vigorous development of my country’s machinery, electronics, light industry, instrumentation, transportation and other industrial sectors, the demand for casting molds has increased in quantity, quality requirements have become higher and higher, and delivery periods have become shorter and shorter. Therefore, the relevant departments of our country have attached great importance to the casting mold industry, listed molds as key scientific research projects in the “Sixth Five-Year Plan” and “Seventh Five-Year Plan”, sent people to study abroad, introduced advanced foreign casting mold technology, and formulated relevant casting mold national regulations. standard.
Rapid Prototype model factories can be divided into plastic prototypes, silicone prototypes, and metal prototypes according to the materials used in the production. The automobile and motorcycle industry is one of the important and important pillars of Guangdong. The production scale of Guangdong’s automobiles and motorcycles provides a huge prototype. The industry has created good development potential. Prototype is the basic and important equipment of industrial products such as machinery, automobiles, electrical appliances, communications, and home appliances. It plays an indispensable role in the development of other industries and has a certain reputation in the world. At present, the supply and shortage of the world prototype market are gradually increasing. In the past few years, the average growth rate of my country’s handboard industry in the past five years has been more than 30%. By 2002, the total value of my country’s handboard industry has been second only to the United States and Japan, ranking third in the world. However, the level of prototype design and manufacturing is generally lagging behind that of developed countries such as Germany, the United States, Japan, France and Italy. The commercialization and standardization of prototypes are lower than the international level to a certain extent. Large, complex, sophisticated and long-lasting prototypes need to be imported.
No matter which process is used to make the hand model, after the processing is completed, surface treatment can be carried out to meet the requirements of corrosion resistance, wear resistance, appearance or other functions of the product. Common surface treatments include: polishing, electroplating, oxidation, phosphating, sandblasting, painting, powder spraying, wire drawing, printing, laser, coating, etc. Surface treatment is a key link that directly determines the quality of the hand model, and is one of the core elements of the technical capabilities of the hand model factory.
