Network interpretation:
1, material additive manufacturing
The structural stability and bonding strength of 3D printing technology are obviously higher than those of traditional methods such as welding. 3D printing based on high energy density laser beam, that is, material additive manufacturing, has changed the manufacturing mode of products and become a research hotspot of Jl in China.
2. AM, additive manufacturing
3D printing technology 3D printing, also known as AM (Additive Manufacturing), is a rapid prototyping technology, and it is a technology to directly manufacture almost arbitrary shapes of 3D entities based on digital model files.
3. Additives
Simulated action. welding, Simufac. Additive (additive manufacturing). Simufact forming software can effectively simulate various forging processes.
Definition, technology and advantages of additive manufacturing;
1, additive manufacturing definition
Additive manufacturing, commonly known as 3D printing, combines computer-aided design, material processing and molding technology. Based on the digital model file, through the software and numerical control system, the special metal materials, non-metal materials and medical biomaterials are stacked layer by layer to create the manufacturing technology of solid objects.
2. Key technologies
The key technology lies in the control technology of material unit. In other words, how to control the physical and chemical changes of material units in the process of accumulation is a difficult point. For example, in direct metal forming, the size of tiny molten pool melted by laser and the control of external atmosphere directly affect the manufacturing accuracy and the performance of parts.
3. Technical advantages
AM technology does not need traditional tools, fixtures and multiple processing procedures, and can quickly and accurately manufacture parts with any complex shape on one device, thus realizing the "free manufacturing" of parts, solving the forming of many parts with complex structures, greatly reducing the processing procedures and shortening the processing cycle. Moreover, the more complex the product structure, the more significant the role of its manufacturing speed.
