Nowadays, more and more 3D printing products are emerging in the market. 3D printing technology has evolved from the initial model printing to automotive, aerospace technology, medical education, building flow, technology research and development. From an economic point of view, 3D printing can undoubtedly greatly reduce the time required to make complex and need fine models. Also in the field of automobile manufacturing, 3D printing can produce product parts through technology, and in other fields, there are more practical novelties and uses. Widely used, such as 3D printing houses, 3D printed bones, 3D printing door locks, 3D printing cars, etc. Below, let's take a look at the development of today's 3D printing technology has some wonderful new applications.
1, unlock the phone
Anil Jain, a professor at Michigan State University, specializes in biometrics such as facial recognition and fingerprint scanning. He hopes to strengthen the cracking of this technology, making it impossible for hackers to start. But the police have a new idea, I hope he can unlock a dead person's mobile phone by 3D printing fingerprints. This is the case. A man was murdered. The police thought there might be some clues in his cell phone, but the police could not unlock the phone because there was no password or fingerprint. However, they did not ask the mobile phone manufacturer for help. Instead, they found Jain and hoped that he could use 3D printing technology to copy the fingerprint of the deceased and unlock the phone.
Finger models printed on current 3D printers often fail to unlock the phone, because many mobile phone fingerprint readers use capacitive technology and rely on closed microcircuits to function properly. The fingerprint on the finger causes some of the circuits to be broken or contacted to generate a fingerprint image. The skin's electrical conductivity is sufficient to close these circuits, but print replicas made of plastic do not have this conductivity, so scientists are covering a 3D printed finger with a thin layer of metal particles, making the fingerprint scanner smooth. Read these fingerprint information. However, this method has yet to be improved. At present, the finger model has not yet been delivered, but after a few weeks, after detailed testing, they will hand over the finger copy to the police. At that time, the police will use a 3D printed copy of the deceased finger to unlock his phone. Regarding the legal issue of copying fingerprints to unlock mobile phones, some experts said that because the person who needs to copy fingerprints has died, and copying fingerprints is necessary to detect the case, the police have no problem of infringing on their privacy rights.
2, print bird eggs
Vultures are animals that feed on dead bodies. People generally do not feel compassionate about this animal, but in order to ensure species diversity, environmentalists at the British International Raptor Center hope to print vulture eggs through 3D printing technology. The way to get rid of the danger of extinction in Africa. The vulture eggs printed in 3D are homogenous and identical to the real vulture eggs. But it has built-in sensors that help scientists collect complex data when vultures hatch. At present, the staff of the International Raptor Center have begun testing the artificial vulture eggs, and the vulture eggs are placed in the nests of the vultures to test the temperature and temperature gradient inside the vulture nests, pressure, humidity, carbon dioxide concentration, light. Strength and rotation data, etc. It is worth mentioning that the project will also be conducted in an open source manner, and the method of making vulture eggs can be viewed on the eggduino website.
3, print weapons
In 2013, the arms dealer Defense produced the world's first 3D pistol, a 38-caliber liberator pistol. In 2014, the company displayed an AR-15 assault rifle that could fire hundreds of 5.56mm bullets. Subsequently, the company developed a Colt CM109 submachine gun. The CM109 is bigger and heavier than the AR-15, and the bullets used are larger, reaching 7.62 & TImes; 51 mm, which is farther than the 5.56 mm bullet range, with greater penetrating power and greater lethality.
Also in 2013, two British journalists purchased a CubeX 3D printer from 3D Systems. After a simple design, they printed 15 pistol parts and purchased a pistol striker from the hardware store. After some simple assembly, it became a real pistol. Subsequently, they passed the security check at St. Pancras International Railway Station during the weekend peak hours and successfully boarded the Eurostar train. Although there were strict security equipment in the train station, the two reporters divided the 3D printing pistol into three parts in the clothes, and put the striker and bullet together, hid in the watch tray, and successfully passed the security equipment of the station. After boarding the train, two reporters assembled the pistol in 30 seconds. The British government was apparently frightened by the two reporters and immediately called on the railway and aviation departments to step up security checks. Radio New Zealand also said: "This is a serious threat to social security. People can print 3D pistols at will and even pass security checks. This is extremely terrible and should attract the attention of the society."
4, print the unborn baby model
Channel Mum, the UK video parenting community and website, recently published a set of information predicting that "3D printed fetuses" will be at the top of the list of childcare items. A number of companies are now offering this service. First, a multi-dimensional color ultrasound image of an unborn baby is converted into a 3D model, and then printed into a life-size plastic model using a 3D printer.
In fact, this technology has existed before, as early as 2012, there have been reports of 3D printed fetuses. In the following years, more and more reports of fetal prints were made. More than 6,000 Youtube users believe Channel Mum's predictions, in a small survey of 1,000 parents, showed that 27% of parents said they would be willing to consider 3D printing unborn baby models.
5, print cosmetics
Looking for a good-looking cosmetic often takes a lot of time and money. But in fact, the raw materials of cosmetics are not too much, but some products are expensive. The Mink 3D printer offers another option for purchasing cosmetics. It uses the same ingredients as the ones sold in the store to print eye shadows and lip gloss. The biggest feature of this printer is that it can adjust the printing color. Whether it is a picture you see on the Internet, the color you choose from the palette, or even the color of your favorite dress, you can print it. come out. Once you have decided which color you want, you can use software to enter the color hex code into the drawing software, and then wait for the machine to print out your own cosmetics. Are the losers and wives tempted? This printer is priced at 200 US dollars (about 1328 yuan), not too expensive, a little better cosmetics than this price.
6, print food
Sci-fi movies can often see such scenes, just press the button and the food you want will be automatically created. However, after the emergence of 3D printing technology, this is not a difficult thing. The Finnish National Research Centre of Finland (VTT) is working on how to apply 3D printing to home-based diet or snack vending machines, enabling consumers to get customized products. The 3D food printer adopts a brand new The electronic blueprint system not only prints food, but also helps people design different styles of food. The materials used in the printer are edible, such as chocolate sauce, batter, cheese, and the like. Once people draw the food pattern on the computer and match the ingredients, the electronic blueprint system will display the printer's operating procedures, and then the food printing process can be completed. In addition, the US military is also very interested in this project, and claims that it does not provide "customized nutrition" according to the physical condition of each soldier. They think that 3D printing technology can realize this idea. It is expected that by 2025, soldiers will be able to detect their physical or nutritional status through wearable devices, which will greatly reduce the cost and time of medical examinations and make it easier to formulate a customized diet.
7, print space equipment
According to a report by the BBC in February this year, a 3D printer will be sent to the International Space Station, the first production facility ever shipped to space. Prior to this, every item that humans sent to space was built on Earth and then launched into space. This method is extremely costly, and the "postage" per gram of space cargo is expensive. Human beings are constantly exploring the space. To survive in space, they must be able to get rid of the earth and produce the necessary parts in space. If the part is too bulky, the space printer will print the parts separately and finally let the robot assemble it into a complete part. This system is called "Archinaut", and the printing and assembly system for oversized parts is expected to take shape within three to four years. In the future, equipment is no longer expected to be shipped to space by launching rockets, but produced directly in space.
Maybe one day, everything in the world can be printed out on a 3D printer. We don't have to go to the mall to buy it. Just press the button at home and you can get what you want. When it comes to this, the otaku girls don’t want it. Hi, hi, my husband's wife can't print it, but also need to invest time and energy to fight for it.
