| 3D printing, one of rapid prototyping technologies, is a technology that creates objects by layer-by-layer printing on the basis of digital model files using adhesive materials such as plastic or powdered metal. 3D printing is usually done using a digital technology material printer, often used in mold making, industrial design and other fields to make models and then gradually used in the direct manufacturing of some products.Now people often mention the 3D printing, mostly based on Popular, simple desktop-based equipment for additive-based manufacturing. In many exhibitions, we can see the figure of the 3D printer.Although it sounds simple, but speaking of the use of 3D printing is really a lot.This paper simply inventory the current 3D printing applications in several major industries for you reference.  3D printing manufacturing handicrafts First, medical treatment In recent years, with the advancement of 3D printing technology, the depth and breadth of its applications in the medical industry have been significantly improved. In the application depth, the early 3D printing can only manufacture cold medical devices, and now has begun to biologically active artificial tissue and organs in the direction of development; in terms of breadth, 3D printing from the initial medical model design and manufacturing, and gradually Developed to directly manufacture medical materials, implants, complex surgical instruments and 3D printing drugs. A few months ago, scientists at Zurich University of Science and Technology developed a 3D printed heart, which touched almost the entire medical technology industry, although the experiment proved that the heart can only support 30-45 minutes due to the material's lack of tenacity. The heart of the new 3D print still breaks through the artificial heart that has been developed in the past, and looks no longer as bulky as a traditional mechanical pump. In addition to 3D printing organs, bone defects, maxillofacial injuries, skull repairs, etc. can not be treated with the usual repair products, and 3D printing products provide an effective solution, especially these prostheses need to be printed according to the patient's Characteristics of the situation for custom production. In addition, 3D printing can help doctors plan medical models, especially for complex operations, which can effectively reduce the risk of surgery and improve the success rate of surgery.Details of 3D printing can also provide a more economical and rapid prototyping for the development of medical devices.Nowadays, With the addition of 3D printing, the healthcare industry tends to be more precise and personalized. Second, manufacturing 3D printing applications in the manufacturing industry, mainly has the following three advantages. 1. Cost Savings: In the case of traditional manufacturing, the shape of the object is more complicated and the corresponding cost is higher.Moreover, the traditional manufacturing machine needs to make objects through cutting, welding and other processes, while 3D printing is to form physical objects by layering. 3D printers do not cost more time, skill, or cost than creating a simple square, making it difficult for people to save money on materials and scrap by-products so they can cut costs.
2. Production diversification: In terms of production materials, conventional manufacturing machines combine different raw materials into a single product, which is not easy because conventional machines can not easily fuse multiple raw materials together during cutting or mold forming. In 3D printing, we have the ability to blend different raw materials together to form new materials that have unique attributes or functions. In addition, the traditional manufacturing equipment has fewer functions and limited types of shapes, and a 3D printer can print various shapes on demand without any purchase of new equipment, requiring only a different digital design blueprint and a batch New raw materials to achieve product diversification. 3. Time-saving and labor saving: The traditional large-scale production line is based on the assembly line, the machine produces the same parts, and then assembled by the robot or the worker. If the product composition is more complicated, the time and cost of assembly is more And more.And 3D printing can make the product integrated molding, do not need to assemble.This will not only shorten the production time, but also save labor costs. In addition, companies can tailor their products to customer needs using 3D printers based on customer orders, while real-time production reduces physical inventories and avoids product build-up. Third, the construction industry In the construction industry, engineers and designers seem to have accepted the use of 3D printing design of building models.During the traditional architectural design process, the use of drawings is not detailed enough to make the building model takes a long time.And the emergence of 3D printing, Not only to quickly meet the needs of designers, the model is also more beautiful, and low cost, environmental protection can save a lot of model making time.
The main advantage of 3D printing in the construction process is that it is environmentally friendly and at low cost, and industry experts have said that 3D printing can reuse construction waste without creating new construction waste, saving 3D printing compared to the traditional building industry Construction materials 30% -60%, shorten the construction period of 50% -70%, reduce labor 50% -80%, according to estimates, 3D printing can at least reduce the construction cost by more than 50%. Although 3D printing in the construction industry has many advantages, but in Xiaobian view, 3D printing is mainly used in the architectural design stage, only a small part of the construction project can be delivered, in order to achieve a wide range of still need some time to popularize. summary: Most of the mainstream applications for 3D printing listed above may be seen in everyday life, but there are also a few products such as 3D printed hearts that people have not seen before, but 3D printing is much more than this , More and more industries have begun to integrate 3D printing technology in them. By referring to the technical principle of ordinary printers, 3D printing provides a brand new manufacturing model for people.Although it shows a great advantage at this stage, but calm thinking, you will find it also has some shortcomings.How to ensure that 3D printing How to ensure the accuracy of 3D printing technology? How to achieve the popularity of 3D printing technology and product production? These are people need to face the problem. Believe in people's joint efforts, 3D printing will bring We are more surprises. |
