The Doctors Performed a Surgery with the Use of a Locally-Produced Titanium 3D Printed Implant in Samara, Russia
A hip arthroplasty surgery involving the use of a custom-made titanium endoprosthesis was performed in the clinic of Samara State Medical University in Samara, Russia. The implant was 3D printed using locally manufactured materials.
Once again, we are going to talk not about familiar desktop CNC machines such as the Flux BeamBox 40W but about large industrial equipment.
The Kolomna Locomotive Works of Transmashholding put into operation a line for the manufacture of diesel engine fuel equipment. The machining centers and CNC machines of the new line will increase the production of parts by 40% and improve the quality of products. Precision fuel equipment is the most complex component of a diesel engine, which directly affects fuel consumption, environmental friendliness, and performance of the machine, as well as its service life.
The new equipment will increase processing accuracy and speed, reduce the number of finishing operations, and increase labor productivity. The production line consists of 24 units of high-precision equipment: machining centers and versatile CNC machines. The costs amounted to 2 billion rubles (about $26,280,000).
The program for the production modernization and the introduction of new equipment was developed by the engine-building center of Transmashholding.
The total volume of the investment program for 2018–2022 is about 12 billion rubles (~$157,720,000). Its implementation should ensure an increase in the quality of existing products, a decrease in production costs, and the creation of new competitive products.
Dmitry Mirny, CEO of the Kolomna Locomotive Works, stated, “We have purchased modern high-tech equipment that will allow the factory to accelerate the process of production modernization, increase production volumes, and speed up diesel engine repairs.”
Welcome all fans of clean code! Today we analyze the PascalABC.NET project. In 2017, we already found errors in this project. We used two static analysis tools (more precisely, plugins for SonarQube): SonarC# and PVS-Studio. Today, we analyze this project with the latest version of the PVS-Studio analyzer for C#. Let's see what errors we can find today, especially when our analyzer has become more advanced and got new features: it can find more exquisite errors and potential vulnerabilities.
UEC NPO Saturn is introducing into mass production the technology of deep grinding with the use of wheels made of cubic boron nitride. The new technological process is designed for the processing of complex sections of gas turbine engine parts made of heat-resistant materials, including 3D printed components.
In this article, we are talking not of desktop 3D printers like the Creatbot DE but about powders for the production of metal parts.
The Tula powder metallurgy plant Polema (part of the Industrial and Metallurgical Holding) has mastered the production of high-entropy alloys and NiCrAlY coatings for import substitution in aircraft construction and other industries. These alloys are suitable for the manufacture of products using 3D printing.
3D scanning technology is widely used in a variety of fields, with the automotive industry being a typical example of such an application. Providing significant advantages in fierce competition among car manufacturers, 3D scanning can be applied throughout the entire vehicle production cycle:
The CAD/CAM College welcomes everyone to the course "Digital dentistry in orthodontics and orthopedics using 3D printing" featuring Evgeny Roshchin, doctor of the highest category, orthopedic dentist, orthodontist, Ph.D. in Medicine, author of thirteen patented methods.
Nowadays, 3D printing solutions are of great interest for companies of any profile. According to experts, by 2025, the global market for additive technologies will be worth $32 billion, and by 2030, it will be $60 billion. 3D printing is actively used for the creation of art modes, in the automotive industry, construction, film industry, and even in the field of fashion. Printing technologies are especially relevant in healthcare — not only as visual aids for future physicians but also for the treatment of various diseases. Many of the latest advances in medical science have been made thanks to 3D printing, and in the foreseeable future, artificial organs and even medicines can be created by means of these technologies. Let's take a look at how 3D modeling and 3D printing help companies achieve great results with relatively small investments.
CreatBot is a 3D printer manufacturer based in China. The CreatBot D600 is one of their most successful devices. This 3D printer can work with various materials, including demanding ones. It offers industrial-grade quality, high level of precision and large-scale 3D printing.
The newer version, the D600 Pro, was developed and released later, in 2018 (the original D600 has been available since 2016). It’s designed to work with an even wider range of materials, including Nylon and polycarbonate.
Both versions feature a massive build volume of 600 x 600 x 600 mm and dual extrusion.
On the stand of the Samara National Research University named after academician Korolev, there are a number of interesting developments, including a mock-up of the AIST-3 satellite and parts of aircraft gas turbine engines obtained using 3D printing technologies.
Stavropol-based Russian company Smart Build launched an open contest of small architectural forms. The winning project will be brought to life with an in-house developed constructional 3D printer.
Eco-friendly invisible car film is a thermoplastic urethane, often self-healing film that is applied to the painted surfaces of a new or used car to protect the paintwork from stones, scratches, crushed insects, and minor damage. It is able to effectively resist natural oxidation caused by prolonged exposure to atmospheric conditions as well as protect the car from scratches and sand.
Recently, one owner of a BMW 3 Series wanted to apply a protective film onto his car but could not find any suitable product on the market. This prompted him to have the invisible film custom-made.
Film for protecting paintwork is divided into two categories: cut on plotters using PC files prepared in advance and cut by hand. The differences between them are as follows: for computer-cut films, the cutting process precedes gluing and is carried out in accordance with the data of the car prototype, with the fitting process requiring high accuracy; installation of hand-cut film is carried out in reverse order.
The biggest advantage of computer cutting is its safety. The hand-made option inevitably involves cutting over the paintwork and removing parts (for example, logo, door handles). During the process, the paintwork can get scratched, while computer cutting is relatively safe.
In addition, computer-cut films, which are delivered as finished products, can significantly reduce raw material costs and operator skill requirements, thereby increasing operational efficiency.
Despite the obvious advantages of computer-cut films, they often impose extremely high data requirements on prototype vehicles — meeting production needs can only be achieved through the availability of large, constantly updated databases. Thus, such films are not suitable for vehicles with non-standard body kits, discrepancies with the factory version, etc.
The exhibition stand iQB Technologies and TWIZE at the Expo Control 2021 event was a good way to see metrological 3D scanners in action. It was held at the Expocentre in Moscow, Russia.
American engineer Dan Fritsche has built a fully functional model of a roller coaster (scale 1:35). The project took around 600 hours to design and model (in Fusion 360) and around 800 more to 3D print, and this is without taking post-processing and assembling into account. And here are the results.
In the beginning of September 2021 Moscow first-graders could visit 17 educational places. Those who participate in the ‘First Grade September’ event will gain knowledge about relevant professions, will visit the programming and 3D modeling courses and will find out more about AR/VR technologies and robotics (you can learn more about educational robotics here).
