Filament Splicer

Project cancelled, click here to read why
The idea for Filament Splicer was born about a month after our Ultimaker 3D Printer was build. As cool as 3D Printing is, printing in one color is boring.

Users of normal, single head FFF/FDM printers are stuck with single color unless they join filament pieces together to produce one multi-colored string. It is not very complicated but process is quite awkward and you will get fed up very quickly.

If you want to have proper, stable filament join you need to have right temperature on the tip of plastic when you connect pieces together. This is hard to achieve when you use some arbitrary heat source. You either underheat or overheat and burn the plastic. Using print head of your printer is best 'ad-hoc' solution but it leaves quite a mess on it, you cannot print when you splice and plastic which is in the head slowly gets burned while you take time to splice your string.

Then, of course there is issue with forming of the joint, carpet knife and fingers where our favorite tools for that job but it took quite a long time to form each joint.

We have had our share of failed prints due to broken joints / stuck filament and finally decided to create a device which will help to splice filament. Initial idea was to create fully automated unit: you place filament ends on copper block, close it, push the button and viola - you have your joint. That was the theory.... In practice this is impossible because PLA and ABS expand during heat-up and contract during cool down, this results in either no joint at all or bubble-filled mess.

Many headache filled days [Even best PLA is really nasty stuff when you breath it in for a while] later we dropped the idea and went for 'open' model with precisely manufactured grooves which help to quickly heat up, connect and form joints.

Thermal insulation was another challenge, we wanted to allow up to 260c temperature but nothing could properly insulate enclosure from hot copper block for prolonged period of time. Ceramic fiber thermal tape can take that heat but one needs a lot of it and then there is itching... Chinese tape is horrible and even best branded, made in USA [ThermoTec] tape is not flawless. We eventually gave up on ceramic fibre and went with PFTA [Teflon] plates. Since PFTA can be outright poisonous at high temperatures, we decided to use high quality - made in Europe material - this way we are sure that maximum temperature of 235c is well within safety limit.

Possibilities
The authors of the study, published May 6 in the journal Monthly Notices of the Royal Astronomical Society, specifically set out to search for Dyson spheres, in the form of infrared heat near stars that couldn’t be explained in any other way.
[url=https://kra30att.cc]kraken сайт[/url]
Using historical data from telescopes that pick up infrared signatures, the research team looked at stars located within less than 1,000 light-years from Earth: “We started with a sample of 5 million stars, and we applied filters to try to get rid of as much data contamination as possible,” said lead study author Matias Suazo, a doctoral student in the department of physics and astronomy of Uppsala University in Sweden.

“So far, we have seven sources that we know are glowing in the infrared but we don’t know why, so they stand out.”

There is no conclusive evidence that the seven stars have Dyson spheres around them, Suazo cautioned.

“It’s difficult for us to find an explanation for these sources, because we don’t have enough data to prove what is the real cause of the infrared glow,” he said. “They could be Dyson spheres, because they behave like our models predict, but they could be something else as well.”

Among the natural causes that could explain the infrared glow are an unlucky alignment in the observation, with a galaxy in the background overlapping with the star, planetary collisions creating debris, or the fact that the stars may be young and therefore still surrounded by disks of hot debris from which planets would later form.
The data used by the researchers comes from two active space telescopes — the Wide-field Infrared Survey Explorer, or WISE, from NASA and Gaia from the European Space Agency — as well as an astronomical survey of the sky in infrared light called The Two Micron All Sky Survey. Also known as 2MASS, the collaboration between the University of Massachusetts and the US space agency’s Jet Propulsion Laboratory took place between 1997 and 2001.

An astronaut’s awe-inspiring views from life in space
[url=https://otzovik.com/reviews/zhilischniy_kooperativ_best_way_russia_sankt...жесткое русское порно[/url]
Longtime NASA astronaut Don Pettit, who has ventured to space four times, returned to Earth on Saturday night from the International Space Station. Pettit, who turned 70 on Sunday, landed at 9:20 p.m. ET in a Soyuz spacecraft with Roscosmos cosmonauts Alexey Ovchinin and Ivan Vagner near Zhezkazgan, Kazakhstan, after a seven-month stay aboard the orbiting laboratory.

The scientist invented the first object patented in space — called the Capillary Beverage, Space Cup or Zero-G cup, which makes it easier to drink beverages in the absence of gravity, and he is also a celebrated astrophotographer known for capturing unique views of the cosmos.
“One of the things I like to do with my astrophotography is to have a composition and a perspective that’s different than an Earth-centric one, typically showing an Earth horizon with the atmosphere on edge, the limb, and then some kind of astronomy, astrophotography, in relationship to that,” Pettit said from the space station during an April 3 interview with astrophysicist Neil deGrasse Tyson.
“Earth is amazingly beautiful when your feet are firmly planted on the ground, and it’s beautiful from space,” Pettit said. “And it’s hard to say what is more beautiful. I think it’s because space is a unique opportunity we seek to focus on the beauty of being in orbit. If we had people living their whole life in orbit, when they come down to Earth, they would probably think that was the most beautiful perspective they’d ever seen.”

Pettit takes his photos from the cupola on the space station, a favorite of crew members due to its seven windows that overlook Earth.

Here are some of his most unforgettable views of what it’s like to live in space that he captured over the past seven months.
