Here are just a few options to make your 3D printed projects even more colorful and impressive. As you can see, 3D printing is about more than just static miniatures. Implement at least a couple of the above projects, and your knowledge in the field of 3D printing (and not only) will expand significantly. Well, if the above electric motor designs are too easy for you, then why not create your own? nine0005

VIAM manufactured the first Russian 3D printed jet engine

Specialists of the All-Russian Research Institute of Aviation Materials (VIAM) completed the first domestic project for the production of a gas turbine engine using additive technologies. The manufactured functional prototype is a promising development of a small-sized engine for unmanned aerial vehicles. According to VIAM CEO Evgeny Kablov, some unique characteristics, including the design of the combustion chamber with a wall thickness of only 0.3 mm, were achieved only through the use of 3D printing. Recall that earlier VIAM produced 3D-printed swirlers for combustion chamber front-end devices for PD-14 engines designed for operation on promising MS-21 long-haul airliners and currently undergoing flight tests. nine0005

3D printing can even be used to print engines.

Pollen Pam 3D printer

The device uses a scheme borrowed from delta robots.

The French company Pollen has introduced a desktop 3D printer that can not only print colored products, but also use granular plastics as consumables. The massive print head is capable of mixing four materials of different types and colors at once, including both conventional thermoplastics and carbon fiber and mineral composites. In order for the bulky head not to interfere with fast printing, the assembly is fixed, and a light worktable is set in motion along all three axes. According to 3Dtoday, the use of granulated plastic instead of filament will theoretically allow not only to reduce the cost of consumables, but also to recycle plastic waste shredded with a shredder. nine0005

Desktop Metal 3D Printing

A 1/2 pound spool of copper or bronze composite is $85.

One of the most cherished areas in 3D printing is the printing of metal products. Unfortunately, this area is almost exclusively represented by industrial installations, whose cost ranges from a few hundred thousand to a couple of million dollars. Available additive technologies are tailored for printing with thermoplastics and photopolymer resins, but there is a possibility to circumvent fundamental limitations. The method consists in 3D printing with composites consisting of polymers filled with metal powder. Such materials are not only outwardly similar to metals, but can also be fired with sintering of metal particles. A series of specialized bars "Filamet" was presented by Virtual Foundry: composites based on PLA and ABS are 88% composed of metal particles. Although a sufficiently high shrinkage is unavoidable during firing, the final products can safely be called all-metal. nine0005

Budget Educational 3D Printer

Printer operation is simplified to the maximum with features such as automatic calibration, and specially designed filaments that do not contain toxic substances will be used as consumables.

Taiwanese company XYZ Printing offers a dedicated da Vinci miniMaker printer for teaching basic 3D printing skills. The device is intended primarily for educational institutions, and its main advantage is its low price, which is only 229dollars. The printer was developed on the basis of the popular da Vinci line, which has found fame as inexpensive, but very high-quality and capable 3D printing devices. Users will also have access to the XYZmaker entry-level 3D editor and the XYZprinting STEAM educational project.

Tomsk Polytechnic University will train developers of 3D printers

Ten state-funded places were allocated for the program, and the first admission to the master's program will take place this fall.

Tomsk Polytechnic University (TPU) announced its intention to train specialists in the field of additive technologies. As Vitaly Drobchik, secretary of the selection committee, explained, the emphasis will be placed not so much on training technicians to service 3D printing equipment, but on engineers capable of developing new technologies and devices. As 3Dtoday notes, the university has the necessary groundwork: TPU is known for the successful development of technologies in the field of production of fine powders, the manufacture of experimental 3D-printed implants from titanium alloys and participation in the project of the first Russian satellite with 3D-printed structural elements "Tomsk-TPU 120", currently awaiting launch from the International Space Station. nine0005

St. Petersburg Prototyping Center

A new prototyping center has opened in St. Petersburg to help small businesses and innovative companies develop and mass-produce new products. The center offers a wide range of tools, including six 3D printers, 3D scanners, measurement instruments and electronic circuit debugging equipment. According to director Sergey Varlamov, the center has already implemented thirteen projects of varying complexity, including 3D printing of a ship power plant model for a large industrial enterprise. The doors of the center are open to companies of any profile. nine0005

3D printed houses

3D printed houses? Easy!

Spanish architects are considering the idea of ​​3D building printing, but refuse to keep up with the rest of the developers. The fact is that Catalan researchers are interested in the possibility of building high-rise buildings, where popular stationary 3D printers will not be applicable due to size restrictions. Instead of fencing skyscraper-tall 3D printers, researchers at the Institute of Contemporary Architecture of Catalonia (IAAC) suggest entrusting the task to teams of small 3D-printing robots that can navigate the walls being erected. In the current version, the tasks are distributed among three groups of machines: the first lays the foundation and prints the first layers of the walls, the second increases the walls in height, moving along the upper layers, and the third crawls directly along the surfaces of the walls, holding with the help of vacuum pumps and strengthening the structure with additional layers of the mixture. Although full-fledged construction with the help of such devices seems to be a matter of the distant future, construction robots may soon find application in the construction of especially dangerous sections of high-rise buildings. nine0005

The first domestic 3D printer for metal printing

Why use only plastic when you can use metal?

Ural Federal University (UrFU) intends to demonstrate its own industrial 3D printer for printing metals using the selective laser deposition method (SLM) at the upcoming INNOPROM 2016 exhibition. According to the First Vice-Rector Sergei Kortov, "the machines do not require the purchase of imported components, in addition, domestic software is used." According to 3Dtoday sources, the share of domestic components and software can reach 80%. The development of an experimental device is carried out for about six months, and similar devices manufactured by the German company EOS were used in its manufacture. nine0005

If the project is successful, it will be possible to eliminate the critical dependence of the domestic additive industry on the supply of foreign industrial equipment for metal 3D printing. The exhibition is scheduled for July 11-14.

3D Printer Group

The software controls the robotic arm that maintains the 3D farm offline. nine0005

It is generally accepted that 3D printing is limited to rapid prototyping, but at least small-scale production is possible and economically justified using 3D printing farms. However, the simultaneous operation of ten or more desktop printers requires the constant attention of the operator, monitoring for possible failures, removing and cleaning finished models, and reloading 3D printers with consumables. Startup Tend.ai came up with a slightly intimidating idea to make the task easier: instead of monitoring ten machines, why not entrust the task to one more machine? To this end, the team is developing a control system with elements of artificial intelligence. nine0005

The high flexibility of the system makes it easy to retrain robots to work with different models of 3D printers, and the number of simultaneously serviced devices in the current version reaches 30 pieces. The commercial premiere of the Tend.ai system is scheduled for 2018.
