How much do you know about 3D printing and 3D printer aluminum profiles?
3D printing is a kind of rapid prototyping technology, which is a technology of constructing objects by layer-by-layer printing based on digital model files, using adhesive materials such as powdered metal or plastic. 3D printing is usually achieved using digital technology material printers. It is often used to make models in the fields of mold making, industrial design, etc., and then gradually used for the direct manufacturing of some products. There are already parts printed using this technology. The technology has applications in jewelry, footwear, industrial design, architecture, engineering and construction (AEC), automotive, aerospace, dental and medical industries, education, geographic information systems, and other fields, so to speak, 3D printing covers Most industries in the society have brought great convenience to our lives. Many design problems are extremely simple under the blessing of 3D printing technology. Today, let’s learn about 3D printing. 3D printers have 3D printers for aluminum profiles. related content.
3D printing has brought about a global manufacturing revolution. In the past, the design of parts and components completely depended on whether the production process could be realized. However, with the advent of 3D printers, this fixed production idea has been completely subverted, which has made enterprises in the production of parts. No longer consider the production process, many problems can be solved easily, any complex shape design can be realized by a 3D printer, so you no longer worry about the design problems, which not only greatly improves the accuracy of machine parts, but also makes it The operation is more sophisticated and smooth.
This important feature can be especially reflected in the aluminum industry, that is, the use of specially customized 3D printers for the processing of aluminum parts, and the accuracy of the product can be controlled to the micron level. This feature is critical and progressive for the refining of aluminum alloy parts of various machines.
There are many defects and deficiencies in our traditional aluminum alloy casting technology. The problems existing in the production of cast aluminum alloys are mainly reflected in the following two aspects.
1. Casting will be accompanied by the formation of many defects during the casting process, such as wrong sides, inconsistent size, insufficient pouring, pores, slag inclusions, pinholes, etc. These defects cause the rejection rate of the casting process to be more than 15%.
2. Due to the slow cooling rate in the casting process, the aluminum alloy grains usually grow abnormally, and the segregation of alloy elements seriously affects the mechanical properties of the aluminum alloy. In addition, cast aluminum alloys have poor weldability in the application process, and are prone to defects such as collapse, hot cracks, pores, and burn-through. At present, the connection problem of aluminum alloy is also a bottleneck restricting its application.
The traditional casting molding process from ingot to machining to the final actual parts requires multiple processes to complete, and the material utilization rate is low. The material utilization rate of some complex parts is only about 10%, and the casting process The requirements of the mold are extremely high, and some small parts with high complexity cannot even be formed by casting methods. Therefore, the limitations of traditional forming processing methods such as casting are becoming more and more obvious in some specific fields (aerospace parts, complex parts for automobiles, mineral processing special-shaped flow parts, etc.).
3D printing technology can specifically solve some of the defects exposed in the above-mentioned casting process, and meet the forming and processing needs of special parts that are difficult or impossible to process during the casting process. With the acceleration of the industrialization process, people’s requirements for the structure and casting performance of aluminum alloy parts are also increasing. Now the development trend of aluminum alloy structural parts is the overall forming of complex-shaped structural parts and the intelligence of the process flow. The rapid production and manufacture of parts with complex shapes, precise dimensions, small and thin walls, and no overall allowance will be the development direction of aluminum alloy parts processing in the future.
Advantages of aluminum applications in 3D printing:
1. Low melting point.
Aluminum has a low melting point, so its 3D printing laser sintering temperature is much lower than other metal materials.
2. Low density.
Aluminum can be used to make light structures and is known as “flying metal”. Therefore, the support requirements required when printing objects are lower than other metal materials.
3. It can be strengthened.
The strength of pure aluminum is not high, and it can be turned into an aluminum alloy by adding various elements to increase its strength.
4. Good plasticity and easy processing.
Aluminum can be drawn into tubes and filaments and extruded into various profiles. There are also reports of FDM printing using aluminum materials.

Disadvantages of aluminum applications in 3D printing:
1. High chemical activity.
After aluminum is made into powder, the surface area is increased, its chemical activity is further increased, it is easy to burn, and the processing safety is low.
2. Low strength and poor mechanical properties.
3. A dense and firm aluminum oxide film is easily formed on the aluminum surface, resulting in difficulty in sintering.
Aluminum alloy materials can overcome the above shortcomings to a certain extent. Aluminum alloy material has a series of excellent characteristics such as light density, good elasticity, high specific stiffness, and specific strength, good wear resistance and corrosion resistance, good impact resistance, good electrical and thermal conductivity, good forming performance, and high recycling and regeneration. .
