On July 1, 2014, the U.S. Navy tested the use of advanced manufacturing technologies, such as 3D printing, to rapidly manufacture ship parts in hopes of increasing mission speed and reducing costs.
The U.S. Navy hosted its first Manufacturing Festival at the Combatant Command System Activity from June 24 to June 26, 2014, with a series of "Print the Ship" seminars during which 3D printing and additive manufacturing technologies were introduced to sailors and other stakeholders.
The U.S. Navy is committed to training sailors in this area in the future. The use of 3D printing and other advanced manufacturing methods can significantly improve mission speed and readiness, reduce costs, and eliminate the need to source ship parts from around the world.
Phil Cullom, deputy chief of the Logistics Section of the U.S. Navy's Operational Fleet, said that given the cost and the existing holes in the Navy's logistics and supply chain, as well as the resource constraints it faces, the use of advanced manufacturing and 3D printing is growing, and that they envision a global network of advanced manufacturers backed by skilled sailors identifying problems and manufacturing products. By the end of September 2014, NASA expects to complete the first imaging telescope with essentially all of its components manufactured through 3D printing technology.NASA has thus become the first to attempt to manufacture an entire instrument using 3D printing. The space telescope is fully functional, and its 50.8-millimeter camera makes it possible to put it into the CubeSat (a microsatellite). It is understood that the space telescope's outer tube, outer baffle and optics frame have all been printed directly as separate structures, with only the mirrors and lenses yet to be realized. The instrument will undergo vibration and thermal vacuum testing in 2015. The 50.8 mm long telescope will be made entirely of aluminum and titanium and will only require four parts to be fabricated through 3D printing technology, compared to conventional manufacturing methods that require 5-10 times as many parts to be 3D printed. In addition, the instrument baffles used to reduce stray light in the telescope can be styled with angles in the 3D printed telescope, which is not possible with traditional fabrication methods in a single part.
August 31, 2014, NASA engineers have just completed the test of the 3D printed rocket injector, this study is to improve the performance of a component of the rocket engine, due to the reaction of liquid oxygen and gaseous hydrogen mixing together in the injector, where the combustion temperature can reach 6,000 degrees Fahrenheit, or about 3,315 degrees Celsius, and can produce 20,000 pounds of thrust, about 9 tons or so, validating the feasibility of 3D printing technology for rocket engine manufacturing. This test effort is located at NASA's Marshall Space Flight Center in Huntsville, Alabama, which has more sophisticated rocket engine testing conditions that allow engineers to verify the performance of 3D printed parts in an ignition environment.
The manufacture of rocket engine injectors requires high precision machining technology, if the use of 3D printing technology, can reduce the complexity of manufacturing, in the computer to establish a three-dimensional image of the injector, the printing of the material for the metal powder and the laser, at higher temperatures, the metal powder can be reshaped into the way we need to look. There are dozens of jet elements inside the jets in a rocket engine, and it takes a certain amount of machining precision to build similarly sized elements. The technology will be used after successful testing to build the RS-25 engine, which serves as the primary power source for NASA's future Space Launch System, a rocket that could carry astronauts beyond near-Earth orbit and into deeper, more distant space. Chris, director of engineering at the Marshall Center, believes that the application of 3D printing technology on the rocket engine injector is only the first step, and we aim to test how 3D printed parts can revolutionize the design and manufacture of rockets and improve the performance of the system, and more importantly, save time and costs and are less prone to failure. For this test, two rocket jets were fired, five seconds at a time, with a complex geometric fluid model created by the designers allowing for a full mix of oxygen and hydrogen at a pressure of 1,400 pounds per square inch.
October 11, 2014 - A team of enthusiasts in the United Kingdom has made a rocket using 3D printing technology, and they're also preparing to lift off the world's first printed rocket. The team presented the world's first rocket made with 3D printing technology to the media at their office in London at local time. Team leader Haynes said that with 3D printing technology, it is not difficult to create highly complex shapes. Even if you want to modify the design prototype, just make changes in the computer-aided design software, the printer will make relative adjustments. This is much more convenient than the previous traditional manufacturing methods. Since NASA is already using 3D printing technology to manufacture parts for rockets, the future of 3D printing technology is very bright.
The project, called Helium-Aided Navigation in Low Orbit, was sponsored by a German data analytics company. Printed out the rocket weighs 3 kilograms, the height of the average adult height, the team spent four years, spent 6,000 pounds to build out. When a ￡15,000 grant is finalized, they will launch the rocket at Spaceport America in New Mexico at the end of this year. A giant balloon filled with helium will lift the rocket to a height of 20,000 meters, a global positioning system installed in the rocket will start the rocket's engine, and the rocket will reach a jet speed of 1,610 kilometers per hour. After that, an autopilot system on the rocket will guide it back to Earth, and a camera inside will film the whole process.
The official website of the National Aeronautics and Space Administration (NASA) reported on April 21, 2015, that NASA engineers are making the first full-size copper-alloy rocket engine part by using additive manufacturing technology to save money, which the head of NASA's Space Technology Mission Department said is a new milestone in the application of 3D printing technology in the aerospace field.
June 22, 2015 reported that the state-owned Russian Technologies Group of Companies has created a prototype drone with 3D printing technology that weighs 3.8 kilograms, has a wingspan of 2.4 meters, and can fly at speeds of 90 to 100 kilometers per hour, with a range of 1 to 1.5 hours.
Company spokesman Vladimir Kutahov said the company took two and a half months to make the leap from concept to prototype, with actual production taking just 31 hours and costing less than 200,000 rubles (about $3,700) to make.
April 19, 2016, the 3D printing technology research center of Chongqing Green Intelligent Technology Research Institute of the Chinese Academy of Sciences (CAS) announced to the public that after more than two years of efforts by the institute and the Space Application Center of the CAS and the completion of the parabolic weightlessness flight test in Bordeaux, France, the first domestic space in-orbit 3D printer was declared a success. This 3D printer can print the largest parts size up to 200 × 130mm, it can help astronauts in the weightless environment of homemade parts needed to significantly improve the flexibility of the space station experiments, reduce the types and number of space station spare parts and operating costs, reduce the dependence of the space station on the ground supply. 3D Printed Liver Model
A scientific research team consisting of the University of Tsukuba and Dai Nippon Printing Co. in Japan announced on July 8, 2015, that it has developed a method to produce a three-dimensional model of the liver that can see internal structures such as blood vessels at a low cost using a 3D printer. The method, if put into practice, is said to make it possible to create a model for each patient, which will help confirm the order of surgery before surgery as well as explain the treatment to patients.
The model was created using a 3D printer based on patient data obtained from medical examinations such as CT. The model presents the overall shape of the liver according to the outer lines of the surface and reproduces in detail the blood vessels and tumors inside it.
Because the inside of the liver model is essentially hollow, the location of important blood vessels and other vessels is readily apparent. A small amount of inexpensive resin material is said to be needed to make the model, reducing the production cost, which was originally about 300,000 to 400,000 yen (about 15,000 to 20,000 yen), to less than one-third of what it would have been.
Models of internal organs made using 3D printing technology are mainly used for research and have not gained popularity in the clinic due to their high price. The research team said they are striving to realize the practical application of liver models by 2016, on the one hand, and will push forward the research and development of organ modeling technology for the pancreas and other organs on the other .
3D printed skull
August 28, 2014, 46-year-old Zhouzhi farmer Hu master in his own house when building, from the 3-story fall after hitting a pile of wood, the left cerebral cap was smashed, in the local hospital after surgery, although the master Hu life is not damaged, but the left cerebral cap depression, in the eyes of others into a "half-head of the man! "
In addition to his unusual appearance, the accident also injured Hu's eyesight and speech. Doctors to help restore his image, the use of 3D printing technology to assist in the design of the defective skull shape, designed a titanium mesh reconstruction of the defective cranial orbital bone, the production of defective left "brain cover", and ultimately realize the symmetry of the left and right.
Doctors said the surgery took about 5 to 10 hours, and in addition to using titanium mesh to support the left side of the brain cover, it was also necessary to take muscle from the leg to fill in. After the surgery, Master Hu's appearance will be restored, as for speech function will have to be seen after the operation to see how it recovers.
3D-printed spine implanted in human body
In August 2014, a team of researchers from Peking University successfully implanted a 12-year-old boy with a 3D-printed spine, the first of its kind in the world. It is understood that the boy's spine grew a malignant tumor after a soccer injury, and doctors had to choose to remove the spine where the tumor was located. However, what makes this surgery unique is that the doctors did not use a traditional spinal transplant, but instead tried advanced 3D printing technology.
The researchers say the implant works very well with existing bone and also shortens the patient's recovery time. Because the implanted 3D vertebrae would fit so well with the surrounding bone, it wouldn't need much "anchoring". In addition, the researchers have created microscopic holes that help the bone grow between the alloys -- in other words, the implanted 3D-printed vertebrae will grow securely with the original spine, which means they won't come loose in the future.
3D-printed palm cures disability
In October 2014, doctors and scientists used 3D printing to fit a 5-year-old girl in Scotland, England, with a palm.
The girl, named Hayley Fraser, was born with a disability in her left arm and had no palm, only her wrist. In collaboration with doctors and scientists, a specialized prosthesis was designed for her and successfully fitted.
3D-printed heart saves 2-week-old baby with congenital heart defects
On October 13, 2014, Dr. Emile Bacha, MD, of New York-Presbyterian Hospital, told the story of how he used a 3D-printed heart to save the life of a 2-week-old baby. The baby had a congenital heart defect that creates "tons of holes" inside the heart. In the past, this type of surgery would require stopping the heart, opening it up and observing it, and then deciding what to do next in a very short period of time.
But with 3D printing, Dr. Bacha was able to create a model of the heart before the surgery, allowing his team to examine it and decide exactly what to do during the procedure. Whereas the baby would have needed 3-4 surgeries, now one is enough, and the baby, whose life expectancy was thought to be limited, can lead a normal life.
Dr. Bacha said he used the baby's MRI data and 3D printing technology to create the heart model. The entire production process*** cost thousands of dollars, though he expects the production price to decrease in the future.
3D printing technology allows doctors to practice ahead of time, which reduces the amount of time a patient spends on the operating table.3D models help reduce the number of steps in a procedure, making it safer.
In January 2015, at Miami Children's Hospital, Adanelie Gonzalez, a 4-year-old girl with "total anomalous pulmonary venous drainage (TAPVC)," had a weak immune system due to the disease's respiratory distress and could only survive for weeks or even days without corrective surgery. .
Cardiovascular surgeons successfully developed a complex corrective surgery plan with the help of a 3D model of the heart by making an exact replica of the 3D model of the little girl's heart. Eventually, according to the plan, a permanent surgery was successfully carried out for the little girl, whose blood flow is now restored to normal and her body is gradually returning to normal during the treatment.
3D Printing Pharmaceuticals
August 5, 2015, the first SPRITAM (levetiracetam, levetiracetam) instant tablets prepared by Aprecia Pharmaceuticals using 3D printing technology were approved by the U.S. Food and Drug Administration (FDA) to be marketed in the United States and will be sold in 2016 officially. This means that 3D printing technology following the printing of human organs further to the pharmaceutical field, the future realization of precision pharmaceuticals, targeted pharmaceuticals have great significance. The approved "levetiracetam fast dissolve tablets" adopt Aprecia's own intellectual property rights ZipDose3D printing technology.
Pharmaceutical tablets produced through 3D printing are rich in holes and have a very high internal surface area, so they can be quickly melted by a small amount of water in a short period of time. This feature is a boon to some patients with swallowing disorders.
This idea focuses on the problem of patients' demand for quantities of medicines, and can effectively reduce a series of problems caused by the stock of medicines, such as moisture and deterioration, expiration and so on. In fact, the most important breakthrough of 3D printing pharmaceuticals is that it can further realize the dream of tailor-made medicines for patients.
3D Printed Chest
Scientists have recently added a titanium sternum and chest cavity to the traditional 3D printed body parts - the 3D printed chest.
The lucky recipient of these 3D-printed parts was a 54-year-old Spaniard who suffered from a form of chest wall sarcoma, a tumor that forms in bone, soft tissue and cartilage. Doctors had to remove the patient's sternum and some of his ribs to stop the cancer from spreading.
Replacements needed to be found for these removed areas, and the metal disks that are normally used can become unstable over time and are prone to complications. Australia's CSIRO has created a titanium sternum and ribs that fit perfectly with the patient's geometry.
CSIRO designs and fabricates the required body parts based on a patient's CT scan. The staff will design the body parts with the help of CAD software and input them into the 3D printer. Two weeks after the surgery was completed, the patient was allowed to leave the hospital and all was well.
3D Vascular Printer
October 2015, China's 863 program 3D printing blood vessel project made a major breakthrough, the world's first 3D bio-vascular printer was successfully developed and launched by Sichuan Blu-ray Inno Bio-technology Co.
The vascular printer has advanced performance, hitting a 10-centimeter-long blood vessel in just 2 minutes. Unlike the existing 3D bioprinters on the market, the 3D bio-vascular printer can print the unique hollow structure of blood vessels, multiple layers of different kinds of cells, which is the first of its kind in the world. In August 2014, 10 3D-printed buildings were delivered in Shanghai Zhangjiang Hi-tech Qingpu Park, as the local relocation project office space. These "print" building walls are made of construction waste with a special "ink", according to the computer designed drawings and programs, by a large 3D printer layers stacked spray painting, 10 huts of the building process took only 24 hours.
September 5, 2014 - Architects around the world are competing to create the world's first 3D-printed house, a far-reaching breakthrough in housing capacity and customization. In Amsterdam, the capital of the Netherlands, a team of architects has begun work on the world's first 3D-printed house made from renewable, bio-based materials. The building, called Canal House, consists of 13 houses. The project is located on a vacant lot on a canal in northern Amsterdam and is expected to be completed within three years. The "Canal House" under construction has become a public **** museum, where US President Barack Obama once visited. In an interview with BI, Dutch DUS architect Hans Vermeulen said their main goal is "to be able to offer customized houses."
In January 2014, several buildings constructed using 3D printing technology were unveiled in the Suzhou Industrial Park. The buildings included a 1,100-square-meter villa and a six-story residential building. The walls of these buildings were spray-painted by layers of large 3D printers, while the "ink" used for printing was made from construction waste.
July 17, 2015 morning, the 3D printed modular new material villa appeared in Xi'an, the builders in three hours to complete the villa. According to the builder, this three hours to build a well-decorated villa, as long as the furniture can be placed on the handbag to move in. September 15, 2014, the world has appeared in 3D printing buildings, skirts and hats, as well as jewelry, etc., the first 3D printing car also finally came out. The car has only 40 parts, it took 44 hours to build it, and it sells for a minimum of ￡11,000 (roughly Rs. 110,000).
The world's first 3D-printed car has been launched - a new chapter in the automotive industry with the creation of a compact, two-seat family car called the Strati, designed and built by US company Local Motors. The innovation was unveiled at the six-day 2014 International Manufacturing Technology Show in Chicago.
It takes 44 hours to print and assemble a Strati sedan using 3D printing technology. The total number of 3D-printed parts on the entire car is 40, which is very simple compared to the more than 20,000 parts of a traditional car. The curvaceous body is made of black plastic and then wrapped in layers of carbon fiber for added strength, a manufacturing design that is the first of its kind. The car is powered by a battery, with a top speed of about 64 kilometers per hour and an internal battery that allows it to travel between 190 and 240 kilometers.
While the car's seats, tires and other replaceable parts are still made in the traditional way, plans are on the table to manufacture them in 3D. The workshop where the sedan is built has an oversized 3D printer capable of printing large parts up to 3 meters long, 1.5 meters wide and 1 meter high, whereas regular 3D printers can only print something the size of 25 cubic centimeters.
Local Motors of Arizona, USA, demonstrates the manufacturing process of the world's first 3D-printed electric car at the International Manufacturing Technology Expo on Oct. 29, 2014, in Chicago. The electric car is called "Strati", and the entire manufacturing process took only 45 hours. Strati uses a unibody and can reach a maximum speed of 40 miles per hour (about 64 kilometers per hour), and can be driven for 120 to 150 miles (about 190 to 240 kilometers) on a single charge. The Strati has only 49 components; the drivetrain, suspension, battery, tires, wheels, wiring, electric motor and windshield are made using traditional techniques, and the remaining parts, including the chassis, dashboard, seats and body, are printed by 3D printers using carbon-fiber-reinforced thermoplastic.The Strati's unibody is molded in a single piece and printed on 3D printers*** and has 212 layers of carbon fiber-reinforced thermoplastic. Cincinnati was responsible for supplying the large-format additive manufacturing 3D printer used to build the Strati, capable of printing parts up to 3 ft x 5 ft x 10 ft (approximately 90 cm x 152 cm x 305 cm).
Divergent Microfactories (DM), a San Francisco-based company, recently unveiled the world's first 3D-printed supercar, the Blade. The company said the car is made of a series of aluminum "nodes" and carbon fiber tubing connected, easily assembled into a car chassis, so more environmentally friendly.
The Blade is powered by a dual-fuel 700-horsepower engine that can run on either gasoline or compressed natural gas. In addition, thanks to its light weight of just 1,400 pounds (0.64 tons), it accelerates from zero to 60 miles per hour (96 kilometers per hour) in just two seconds, easily placing it among the top supercars.
July 2015, the United States, San Francisco, Divergent Microfactories (DM) company launched the world's first 3D printed supercar "Blade (Blade)". On November 10, 2014, the world's first 3D-printed laptop went on pre-sale, allowing anyone to print their own device in their living room for half the price of traditional products.
The laptop, called the Pi-Top, won't be officially launched until May 2015. But, through word of mouth, it has now racked up ￡76,000 in pre-orders in two weeks.
Clothing and apparel
Many women are well aware that coming across an outfit that fits well is not easy, and clothes made with 3D printers can be a panacea for the dilemmas that women encounter when picking out clothes. A design studio has successfully used 3D printing technology to create clothing that not only looks new, but also fits comfortably.
The dress, which costs 19,000 yuan, was made using 2,279 printed panels connected by 3,316 chains. Dubbed the "4D skirt," the garment can be easily stretched out of its compressed state, just like a woven garment. Jessica, one of the founders and creative director, recalls that the dress took about 48 hours to print.
The Massachusetts-based company also wrote an app for smartphones and tablets, which helps users adjust their clothes. Using this app, one can change the style and comfort of the clothes.
Shadowless High Heels
August 27, 2015, SexyCyborg, a beautiful creator from Shenzhen, invented the "Shadowless High Heels". It's empty inside and can fit a security penetration testing toolkit inside.
The "shadowless heels" are enough to allow some beautiful hackers to easily break through the defenses of certain companies or government agencies and gain access to valuable and important information. Inside each shoe is a drawer that the user can remove without taking off their shoes. Then a penetration test kit is put in, with components that are used by hackers.
