3D printing, also known as additive manufacturing, can be printed layer by layer through preset programs, digital models, powder spraying, etc., and finally obtain high-precision three-dimensional products. As a cutting-edge technology in the field of industrial manufacturing, 3D printing integrates a variety of technologies, including layered manufacturing technology, mechanical engineering, numerical control technology, CAD, laser technology, reverse engineering technology, material science, etc., which can be directly, quickly, automatically and accurately transform the design electronic model into a prototype with a certain function or directly manufacture parts, thus providing a low-cost and high-efficiency means for the production of part prototypes and the verification of new design ideas.
The basic principle of 3D printing technology is the reverse process of tomography. Tomography is to “cut” something into countless superimposed pieces, and 3D printing is to generate three-dimensional solid technology by adding materials layer by layer through continuous physical layer superposition, so 3D printing manufacturing technology is also called “additive manufacturing”. technology”.
The advantages of 3D printing are: First, “what you see is what you get”, printing can be completed at one time without repeated cutting and grinding, which simplifies the product production process and shortens the production cycle. The second is that in theory, the cost advantage of mass production is large. 3D printing completes product manufacturing with a high degree of automation, and the labor cost and time cost are relatively low. The third is that the precision of the product is higher, especially in the manufacture of precision parts, the accuracy of the products obtained by 3D printing can reach the level of 0.01mm. Fourth, it is highly creative, which is suitable for personal creative design.And it has great potential to tap consumer grades.
3D printing has a wide range of applications, and it can be called “everything can be 3D printed”. It has been applied in many fields such as construction, medical treatment, aerospace, and automobiles.
In the construction industry, 3D printing technology is combined with BIM technology to build a three-dimensional model of the building in the computer and then print it out. Through the 3D stereoscopic architectural model, technical support is provided in architectural display, construction reference, etc.
In the medical industry, it is mainly used in orthopedic diseases, surgical guides, orthopedic braces, rehabilitation aids, and dental restoration and treatment. In addition, there are surgical planning models. Doctors use 3D printing technology to make pathological models, design surgical plans, and conduct surgical rehearsals to improve the success rate of surgery
In the field of aerospace, 3D printing can be used to produce high-precision parts that meet design standards and usage requirements, such as engine turbine blades, integrated fuel nozzles, etc.
In the automotive field, 3D printing technology is applied to the research and development of auto parts ,which can quickly verify the working principle and feasibility of complex parts, shorten the process and reduce costs. For example, Audi uses the Stratasys J750 full-color multi-material 3D printer to print out Fully clear multicolor taillight shade.
The scope of JSADD 3D’s 3D printing services is gradually rising and mature. It has great advantages and relevant excellent model cases in the medical industry, shoe industry and automobile industry.
