Why did we choose VENUS as a name?
We dedicated our titanizum alloy nozzles to VENUS-7, a legendary probe made of the same material as well as the natural desitre of humanity to discover new spaces! Venera 7 was the first spacecraft to return data after landing on another planet!
Venus, Earth's closest but mysterious planetary neighbor had become even more of an enigma as discoveries made by the early Soviet probes during the 1960s had shattered earlier beliefs that the similarly sized world was an "Earth-like" planet. Direct measurements left no hope for finding "warm oceans" on the planet's surface as it had been still believed just a decade earlier. The first Venera probe, launched in 1967 and designed to withstand around 10 atmospheres of pressure, had been obliterated at an altitude of around 26 kilometers by pressure that reached around 15 atmospheres.

The first Venera probe, launched in 1967 and designed to withstand around 10 atmospheres of pressure, had been obliterated at an altitude of around 26 kilometers by pressure that reached around 15 atmospheres.
The probe was designed to withstand higher pressures and temperatures, as well as the shock of landing, through the use of a single spherical shell with no seams, welds, or holes. Titanium was used in the construction of the pressure vessel, and it was lined with shock absorbing material. Later analysis of the recorded radio signals revealed that the probe had survived the impact and continued transmitting a weak signal for another 23 minutes. It is believed that the spacecraft may have bounced upon impact and come to rest on its side, so the antenna was not pointed towards Earth. The pressure sensor had failed during the descent, but the temperature sensor showed a steady reading of 475 C at the surface, and a pressure of 93 bar with a wind of 2.5 meters/sec was extrapolated from other measurements. But I am getting ahead of myself. Let's go back to the start of the story.
Venera 7 was the first spacecraft to return data after landing on another planet.
My Name is Michael Kirieiev and I am head of R&D at Extrusion in Motion. At the beginning of my career I was one of the designers responsible for the development of Soviet planetary spacecraft. After carefully reviewing available data, our team decided to design new probe called VENUS to withstand up to 180 atmospheres. To survive the landing, a pair of landers scheduled for launch toward Venus in 1970 were each "packed" into a titanium alloy shells.
In December 1970, the spacecraft, approached Venus after a rather uneventful flight. On December 15, the VENUS-7 lander separated from its cruise stage and plunged into the planet's atmosphere on the dark side of the planet, which was facing Earth. Unfortunately, scientists on the ground discovered that due to malfunction of a mechanical switch on the probe, the spacecraft had lost the capability to transmit all but a single channel of data. We were lucky, this switch stuck on a temperature reading - temperature data can allow to estimate pressure too, because they are related. As VENUS-7 descended into the Venusian atmosphere, it continued transmitting temperature data down to an altitude of around 10 meters. Then another disaster struck. At this point, the probe's parachute was lost and the spacecraft plummeted toward the surface of Venus. The mission was seemingly over - the deep-space control station in Crimea was receiving nothing but background noise from the emptiness of space. More stunning was the news a week later, when experts from the Moscow's Institute of Radio Electronics told us that they had been able to discern VENUS-7's signal from the background radio noise recorded after the landing. |
After deciphering a very weak signal, the scientists confirmed that for around 23 minutes after hitting the surface of another world, VENUS-7 had continued transmitting temperature data. That was despite the fact it was laying on its side in darkness with its antennas pointed away from Earth.
The hardy titaninum spacecraft had delivered the first measurements conducted directly on the surface of another planet. The data confirmed what has already been speculated about the "weather" on Venus - the surface temperature was 475 degrees Celsius - enough to melt such metals as lead or zinc. The atmospheric pressure at the surface turned out to be around 93 atmospheres, comparable to an ocean depth of 800 meters on Earth.

With these M6 titanium nozzles, designed for 2.85mm filament, you can use on your Ultimaker highly abrasive filaments like carbon, bronze, copper, steel, graphene as well as polymer materials like ABS, PLA, CPE/CPE+, TPU, PP, PC, Nylon. Expand the universe of your 3d projects together with special nozzles which have a legend inside!
Let me walk you through the reasons to produce titanium nozzles for 3D printers Ultimaker...
Michael Kirieiev, Ph.D.
Head of R&D
Our company is authorized reseller of Ultimaker in Ukraine and some of our customers are Ukrainian manufacturers of small aircraft (e.g. drones, quadrocopters). Some quadcopter framesrequired the use of non-standard polymer materials - for example, carbon fiber XT-CF20. With a high melt strength and great dimensional accuracy and stability, XT-CF20 is the perfect filament for sturdy prints like parts for drones. The XT-CF20 is a blend of the Co-polyester filament and chopped carbon fibers (not less than 20% of fibers). XT-CF20 has the proper stiffness, toughness, manufacturability properties and abrasivity....
CARBON FIBER IS VERY ABRASIVE
What does it mean?
What does it mean?
A special point of attention is the abrasive nature of the carbon fibers. In general these fibers will accelerate the nozzle-wear of brass nozzles, much faster than unfilled filaments.
Therefore we have developed VENUS over the last one year and it has undergone extensive research, customer's painpoints surveys, development and prototyping. We have taken on board feedback from customers which use brass and steel nozzles to print abrasive materials and VENUS offered today is a highly developed market ready professional titanium nozzles.
For VENUS project, we developed clamping cartridge for 0.4, 0.6 and 0.8mm drills and a special shank for this cartridge.
Before shipping to the customer, we control visually the quality of our titanium alloy nozzles
Our Extrusion in Motion's facility is equipped with several state of the art milling and turning machines that are great suited for the precision machining of complex designs. They can accommodate work pieces from .25" to 6" in diameter, .25" up 48" in length, weighing up to 35 lbs. By joyning our state of the art machines with our experience, we can provide you with the strong quality of VENUS nozzles.
These machines in the hands of our experienced staff equal high precision results. For our titanium nozzles and heater blocks we can achieve tolerances of ±.0001" straightness, ± .00025" concentricity, ±.0002" inner/outer diameter, and ±.001" on length.
We use own assembled CNC machine to produce titanium nozzles

Testimonials
We produce security cams and video doorbells. Usually we try a lot of polymer meterials to find something special, strong and reliable, applicable for our end products. XT-СF20 is one of them, this is definitely one of the filaments with challenging print and great reward. Thanks to EIM's titanium nozzles, our carbon prints are great where strength is extremely high for 3D printed parts of cams and doorbels.
Pavlo Deresh
Projects manager at RING
We develop cources for children and young people covering coding and robotics. As Ultimaker 2E+ owner, I use titanium nozzles and various materials like copper, carbon, PLA and Nylon to create strong housings for various devices. We are satisfied with the high quality of titanium nozzles, which allows us to obtain high quality of the printing layer for different types of filaments.
