Electronic and electrical appliances are the necessities of people's life, such as: air conditioning, LCD TV, refrigerator, washing machine, audio, vacuum cleaner, electric fan, heater, electric kettle, coffee pot, rice cooker, juicer, mixer, microwave oven, oven, bread maker, shredder, mobile phone, various small appliances, etc. In order to win the favor of consumers, these products generally pursue the fashionable appearance and stable performance. If manufacturers want to make profits in the competitive market, they must constantly launch better and better new products. The speed of upgrading is increasing year by year.

For example, small household appliances generally focus on the change of surface modeling. If you directly use computer 3D drawing in the design, you always get twice the result with half the effort. Even if the model is established, its subsequent modification is poor; If we do the opposite, we can obtain 3D modeling data by 3D mapping with reverse engineering technology (commonly known as copy number), and then use reverse design software to carry out CAD drawing, and then complete the modification design. The formed 3D model data can be used in the production of hand model, which can greatly improve the design efficiency.

In addition, the characteristics of electronic products are small, thin and soft, and there are many thin-walled parts, so the traditional contact measurement method is often not applicable.

And in the process of product design, the visualization of design is very important, which is the cornerstone of design communication and design improvement. Using 3D printing technology to quickly make the physical model of the design, compared with the 2D model in the plane or the virtual 3D model in the computer, the intuitive hand model can reflect more design details and is more intuitive and reliable. It is understood that Panasonic uses 3D printers to shorten the mold production time by half, and the cost is also greatly reduced, thus reducing the production cost of resin products.

The application of 3D printing technology in the field of electronics and appliances is mainly in the following aspects:

1. In the early stage of product design, 3D printing equipment is used to quickly make enough models for evaluation, which not only saves time, but also reduces design defects.

2. Assembly test, function test, to achieve the goal of product function improvement, production cost reduction, better quality and market acceptance.

3. Mold prototype, to speed up the delivery cycle, reduce customized price, improve product delivery quality, and improve production efficiency.

3D printing can help optimize the design, accelerate the progress of product launch, and create value for enterprises

3D printing is an ideal choice for rapid production of different hand prototype, which can help realize cross department design communication and design discussion, and make enterprises make more intelligent choices;

Unlike the traditional open mold manufacturing or manual model making, 3D printing is faster, cheaper, and has realistic and intuitive effects. Even if making multiple prototypes, the cost is not high;

Compared with 2D drawings, the hand model has irreplaceable advantages. The details of the product are more clear, and the visual experience of the product is more intuitive. Each member of the design team can feel the appearance design effect through direct contact, so that the discussion of design modeling is established on a more realistic basis;

Designers can print out the details of the design at any time, and verify the effect of the new design;

Some 3D printing technologies can directly and quickly manufacture products that can not be manufactured by traditional technology without the limitation of product design structure and shape, thus greatly releasing the design potential of designers and providing them with more design freedom;

3D printed samples can be used for publicity, market research, trial sales, etc.

The application of 3D printing technology in the domestic medical industry began in the late 1980s. Initially, it was mainly used for rapid manufacturing of 3D medical models. At that time, 3D printing technology was mainly used to help doctors communicate with patients, accurately judge the condition and carry out operation planning. It can be said that the exploration of the application of 3D printing technology in the medical industry in our country has a long history, and it goes deep with the development of 3D printing technology.

In recent years, with the development of 3D printing technology and the growth of precision and personalized medical demand, 3D printing technology has been widely and deeply applied in the medical industry. In terms of application scope, from the initial rapid manufacturing of medical models, it has gradually developed into 3D printing direct manufacturing of hearing aid shells, implants, complex surgical instruments and 3D printing drugs. In terms of depth, 3D printing of inanimate medical devices is developing towards printing of bioactive artificial tissues and organs.

Medical model

3D printing technology is very intuitive to restore the specific situation of lesions, effectively reduce the risk of surgery, and solve the confusion of patients and their families. For example, most of the CT and MRI examination results in medicine now look like black and white light. There is a certain fuzzy boundary for the accuracy judgment of difficult lesions. Before surgery, according to the patient's CT or MRI data, a three-dimensional data model suitable for 3D printing is synthesized by software, and then printed out by 3D printer to obtain an accurate medical model, It is helpful for doctors to plan the operation plan. Especially for complex surgery, it can reduce the risk of surgery and improve the success rate of surgery.

It is reported that in 2015, Shanghai First People's hospital used 3D printing technology to carry out living donor liver transplantation for a patient with congenital autoimmune cirrhosis and portal hypertension. In order to make the operation plan accurately, 3D printing technology was used. 3D printing presents the patient's hepatobiliary and pancreatic organs and the corresponding lesion parts in the form of 1:1 "real object" in front of the doctor. By accurately evaluating the three-dimensional spatial relationship between the lesion area and adjacent organs and tissues, real-time comparison is carried out during the operation. By adjusting the 3D printing model and placing it in the best anatomical position, the key parts can be quickly identified and located, It provides intuitive real-time navigation for the key steps of surgery. Through accurate positioning of lesions and blood vessels, real-time guidance of important vessels, the accuracy of operation is improved, and the operation risk is effectively reduced.

Surgical guide plate

Surgical guide plate is an important tool for doctors to assist in surgery. As an important tool of auxiliary surgery, 3D printing surgical guide is of great significance. As a powerful tool to achieve precision surgery, the surgical guide is based on 3D reconstruction and surgical simulation. It is designed and printed digitally to help doctors implement precision surgery, effectively improve the accuracy of surgery and shorten the operation time.

3D printed surgical guides are more cost-effective in the following situations:

-Complex design that cannot be realized by traditional methods

-Meet the individual needs of unique diseases or patients

-Function integrated design

3D printing technology is especially suitable for manufacturing irregular or personalized guides.

Rehabilitation apparatus

With the rapid development of digital technology and medical science and technology, 3D printing technology has been widely used in the field of medicine. With the help of 3D printing technology, doctors can turn the virtual image into a solid model, resulting in a new way of surgical treatment and follow-up rehabilitation, which is different from the traditional methods, bringing new ideas and working modes to the medical field. As far as the rehabilitation of hand surgery is concerned, 3D printing technology can completely simulate the characteristics of patients' rehabilitation parts, and the individualized rehabilitation brace made by 3D printing can increase the individualized accuracy of the brace, so that patients can obtain the "private customized" rehabilitation experience. 3D printing rehabilitation devices include orthosis and bionic hand, personal mobile aids, communication and information aids, personal medical aids and other rehabilitation aids. The real value is not only to achieve accurate customization, but also to make accurate and efficient digital manufacturing technology instead of manual production and shorten the production cycle. For example, uniiontech evodent series 3D printers can print 70 hearing aid shells or models in about 60 minutes. As a kind of personalized auxiliary therapy, 3D printing rehabilitation aids play a very important role in modern medicine and have a bright future.
