    The Russian aerosol 3D printer will make it possible to create electronic boards on plastic surfaces of any shape using a directed flow of nanoparticles. As a result, solar panels can be printed directly on the roofs of cars, and mobile phone elements such as receiving and transmitting antennas will begin to be embedded in their housings, reducing the dimensions of the devices. The new technology can also be used to create a conductive basis for flexible screens, which will make them more economical. An experimental prototype of the printer has already been created, and its industrial version may appear in the coming years.

    I wonder if they have a manual mode on their CNC machines, creating prototypes with CNC would be painful, but CNC is wonderful for mass production.

    I would think CNC machines would be excellent for fast prototyping too... make things in plastic or wood first and check fit and finish and shapes... the software with collision detection would detect design conflicts where parts wont move the way they need to etc.

    For a prototype it would be quick and easy to reshape and redesign parts on the fly when needed... then when you have what you want you can then use normal materials and shift to mass production.

    Since all is now designed using CAD software why CNC should be bad for prototyping? all data, settings are already in digital form?

    Exactly... the goal is to get the digital design of a product that works and has no weaknesses or faults, so for fast prototyping you can whack out a few test examples that can be tested and tweaked and improved till you get the best design... once you have that then you make it in the powdered metal expensive but stronger materials and give that a proper test and then once it has passed you examine any possible refinements to make it cheaper or faster to make... test that and then you have the digital design for serial production ready to go.

    I think that the better systems can take software produced models and render them into physical reality much faster
    than before. Back in the good old days one had to program in NC specific languages. Today you do not have to touch
    any code for an NC machine.

    One of the critical advantages the US had in the cold war regarding designing new shapes for things was their access to super computers allowing thousands of shapes a day to be tested for very high speed (space shuttle design) and also for stealth shapes.

    The Soviets didn't even bother designing their own shape for Buran after NASA spent 2 billion dollars on thousands of external shapes based on the aerodynamics of an object entering the atmosphere from orbital speeds with the materials and production limitations of the time.

    They adopted the shape and saved an enormous amount of time and money... and it worked rather well despite being fundamentally different in actual design... the Buran is a glider launched on a rocket, while the Space Shuttles are super heavy aircraft with enormous external fuel tanks for the fuel energy to get to space and huge solid rocket boosters or JATOs to get moving.

    It was only after the US stole the maths of radar propagation from a Russian scientist that their ability to create stealth aircraft actually became practical and useful... physically testing a few wooden shapes a week just does not cut it.

    Modern CNC machines use digital models... everything is digital.... early CNC machines are like early mainframe computers with punch card programming.

    You can now get three D printers that can take lasers or cutting tools or plastic or metal powder 3D printer attachments... very versatile and clever to make parts or layer by layer build parts, or burn shapes in materials etc etc...

    As I posted before, the USSR had the basic shape of the the Buran at least before 1967 and there is a picture of Gagarin and others
    posing together with the model. Maybe the Soviets "stole" some of the US design, but they would not need to. They clearly could
    design aircraft without those overrated supercomputers (which were junk in the 1970s by even late 1980s standards). The Shuttle
    and Buran shape is dictated by the function. A glider entering from space into the atmosphere and being able to carry a bulky payload
    on the way up (or down). It really is a case of minimizing around the same local minimum in design parameter space. Giving either
    of them distinctive characteristics in wing shape and body shape introduces spurious cost and degrades reliability. The only "theft"
    is the absolute size. Here I see the decision being made to follow the US model to achieve parity. Making it smaller would reduce
    its potential and making it larger would increase cost of the whole system including the launcher and would also reduce reliability.

    I doubt that the USSR stole the Shuttle tile technology since it had enough scientific base to come up with its own light ceramics
    and the glue to attach them to the Buran fuselage.

    The Toshiba NC "scandal" was more plausible since it could have involved submarine screw shape rendering flexibility. But then,
    the USSR would still need its own shape design and had the deep knowhow to achieve this.

    The whole "Toshiba affair" is something I find particularly bizarre.
    We are talking - I will say that again - a nation that operated its own desigh&build subs since 1880.
    Holding all the records you could get, one by one. Fastest, deepest diving, bigger ice crushing capability, biggest etc. The only one in the world, where the designers were focused enough on safety, to place a rescue chamber as a piece of standard equipment. And this rescue chamber has proven working&saved the lives of the Komsomolec crew.
    Advanced and automated enough, to have crews numbering half of the competitors while serving the same tasks.
    Enough to compare Lira class. It used to be a submerged Ferrari if we compare that to its opponents.
    And now, we are being told, that all that record achievements were a piece of shit because they didn't have the machines good enough to make a propeller right?
    Even if so, with the manpower in the possession, they could shape the propellers by hand if needed Laughing

    The reality is that the Buran differs from the Shuttle even in aerodynamics. Its aerodynamic quality is BETTER. Just because the USSR had a tremendous experience in creating aircraft, and such world-class scientific centers as GLITZ and TsAGI.

    Shuttle and Buran are similar only because they have similar functions. However, upon closer examination, they are completely different, even at the level of concepts. The Buran has more optimal aerodynamics, higher energy capabilities, and is more flexible in application. You can overlay the contours of the Buran and the Shuttle - and see that they are different.

    Main difference is that the space shuttle is the space launcher = the main engines are build into it. Buran was part of the Energia/Buran combo which was much more flexible to use. Energia could work alone while the americans had to pack the shuttle with six people just to bring a satellite into space.

    The shapes are nearly identical because they consist of three elements:

    1) Delta wings blending into a lifting body.

    2) "Squared off" cylinder fuselage to accommodate more payload volume.

    3) Aircraft type nose section.

    There is not much room for flowery design in all three categories. Some details are nearly identical. They could have
    been token differentiated but why bother. The American design experience was absorbed by the Soviet designers of
    the Buran. It is not embarrassing and Americans should take some pride and credit. But Americans also love to
    spread shit around that they were totally ripped off. Like their drivel about the Tu-95 being a copy of the B-29.

    Post  GarryB Fri Oct 29, 2021 10:30 am

    My understanding of what happened was filtered through the lense of the western expert...

    The Soviets certainly had small space plane designs which they tested well before Buran... but the aerodynamics capacity and ability of the Soviets should not be underestimated.

    They can often adopt ideas, but normally will adapt them to their own needs and also apply new technology to make them better.

    A space shuttle made during that period is not just limited by aerodynamics... it has to have an internal volume to take the crew and any payload and equipment the Shuttle is to use during its entire life span without needing modifications of course.

    The design is also limited by knowledge of the boundary layer of air and space and aerodynamics at mach 20+ is not a solid fully researched area back then.

    Another factor is also materials science and manufacturing capacity... getting a US copy to copy directly does not help a lot if you don't have the materials or the production capacity to make it to that level of precision.

    Variation on the MiG-15s wing was about 5mm which is fine for a subsonic jet, but would be catastrophic for a stealth aircraft, and could be fatal for a supersonic fighter in terms of flight performance...

    The key difference between the shuttles is that if you are building a new space station you can take the Buran off the back of the Energyia rocket and place a complete section of a space station with a nice aerodynamic fairing up to 120 tons in weight and launch it in one piece... 3-4 launches and you could build a rather useful space station... where each launched block locks together easily and simply.

    Buran was not really a copy. The general shape was adopted, but the engineering is fully indigenous Soviet.

    Russia "copied" the Shuttles overall shape just like Sierra Nevadas "Dream Chaser" is a copy of the BOR-4 subscale lifting body test vehicle.

    The sentry robot used at the Vostochny Cosmodrome (named 'Marker') is an autonomous system.   That is, it is a real
    robot and not a remote controlled toy.   It was tested by being sent on a 100 km trip where only the end point was issued
    as an instruction.

    1) It determined the path by itself.

    2) It launched a recon drone 20 times all on its own initiative.   This was not preprogrammed.  

    The robot has a AI (seems like world class to me) that engages pattern recognition of the images it gathers through
    its cameras and its drone.  

    The successor model to Fyodor is being developed and will be released in 2023.   It will have tactile sensors which
    indicates to me that its AI, developed with the experience from Marker, is expanding.

    Both the Marker precursor and Fydor were the focus of derision by the usual suspects wanking themselves silly
    about Russian genetic inferiority.   Now these clowns have nothing to say and the US press is sounding alarms
    about Russia developing advanced robotics tech.

    and I'm happy about non military part here. Just because , I am sure military robots in Russia will do well so I don't really worry about them Laughing Laughing Laughing .

    However applying this hi tech in civilian market is to me awesome news! Agricultural robots are really future market you cannot neglect, logistics too or medicine. I hope industrial will follow.

    Also in the nuclear industry having remote control robots could make things much safer and allow things to be done in environments that would make human solutions lethal...

    Even remote surgery where a doctor in one part of the country can perform operations in a distant and more remote part of the country... which could lead to an AI surgeon that can perform more minor surgeries freeing up doctors for more difficult ops either locally or remotely.

    The problem with nuclear is that in high radiation environments advanced electronics with microcircuits tend to glitch and fail.
    So you end up with quite different solutions than you would otherwise.
