What is 3d printing rapid prototyping technology

 

  3D printing technology

 

A technique for layer-by-layer printing. By connecting a computer with a 3D printer, the drawn drawings can be printed out as a means of model. Today, this technology is used in many fields, and people use it to make clothing, architectural models, cars, chocolate desserts, and more.

 

The advantages of 3d printing technology

   3D printing is very different from traditional production through molds. The biggest advantage of 3D printing is that it can be produced without machining or any molds.

 

Generate parts of any shape directly from computer graphics data, thereby greatly shortening product development cycles, increasing productivity and reducing production costs. At the same time, 3D printing can also print some shapes that cannot be produced by traditional production technologies. At the same time, 3D printing technology can also simplify the entire production process and is fast and effective.

 

3D printing technology process principle

 

   The printing process of each layer is divided into two steps. First, a layer of special glue is sprayed on the area to be formed. The glue droplets themselves are small and difficult to spread. Then a uniform layer of powder is sprayed. The powder will quickly solidify and bond when it encounters the glue, while the areas without glue remain loose.

 

In this way, under the alternation of one layer of glue and one layer of powder, the solid model will be "printed" and formed. After printing, the model can be "planed" by sweeping away the loose powder, and the remaining powder can be recycled.

 

   Printing consumables are changed from traditional ink and paper to glue and powder. Of course, glue and powder are special materials that have been processed, which not only requires the speed of curing reaction, but also has a direct impact on model strength and "printing" resolution. The 3D printing technology can achieve 600dpi resolution, and the thickness of each layer is only 0.01 mm. Even if there are text or pictures on the surface of the model, it can be printed clearly. Restricted by the principle of jet printing, the printing speed will not be very fast. The more advanced products can achieve a vertical speed of 25 mm per hour, which is 10 times higher than that of the earlier products, and can use colored glue to achieve color printing, color depth. Up to 24 bits.

 

   Due to the high printing accuracy, the quality of the printed model is naturally good. In addition to the design that can express the shape and curve, the structure and moving parts are not a problem. If it is used to print mechanical assembly drawings, gears, bearings, tie rods, etc. can all move normally, and the morphological features such as cavities and grooves are positioned accurately, and can even meet the assembly requirements. The printed entity can also be polished, drilled, and electroplated. etc. for further processing. At the same time, powder materials are not limited to sand mold materials, but also other materials such as elastic expansion, high-performance composite, and investment casting are available.

 

Features

 

  3D printing has brought about a global manufacturing revolution. In the past, the design of components was completely dependent on the realization of the production process. The emergence of 3D printers will subvert this production idea, which makes companies no longer consider production when producing components. Process issues, any complex shape design can be realized by 3D printer.

 

   3D printing can generate objects of any shape directly from computer graphics data without machining or molds, thus greatly shortening the production cycle of products and improving productivity. Although it still needs to be perfected, the market potential of 3D printing technology is huge, and it is bound to become one of the many breakthrough technologies in the future manufacturing industry.

 

   3D printing has made these types of printers available at some electronics stores, and factories are also selling them directly. Scientists say that the use of 3D printers is still limited, but one day people will be able to 3D printers to print more practical objects.

 

   3D printing technology is critical to NASA's space exploration missions, and more than 30% of the existing spare parts of the International Space Station can be manufactured by this 3D printer. The facility will use polymers and other materials to build objects layer by layer using extrusion additive manufacturing. The 3D printing experiment is one of NASA's key research projects in the future. 3D printing parts and tools will enhance the reliability and safety of space missions, while reducing the cost of space missions because they don't have to be transported from Earth.
