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.

Groundbreaking telescope reveals first piece of new cosmic map
[url=https://kr13at.cc]kra13 at[/url]
Greetings, earthlings! I’m Jackie Wattles, and I’m thrilled to be a new name bringing awe to your inbox.

I’ve covered space exploration for nearly a decade at CNN, and there has never been a more exciting time to follow space and science discoveries. As researchers push forward to explore and understand the cosmos, advancements in technology are sparking rapid developments in rocketry, astronomical observatories and a multitude of scientific instruments.

Look no further than the missions racing to unlock dark matter and the mysterious force known as dark energy, both so named precisely because science has yet to explain these phenomena.

Astronomers have never detected dark matter, but they believe it makes up about 85% of the total matter in the universe. Meanwhile, the existence of dark energy helps researchers explain why the universe is expanding — and why that expansion is speeding up.
Extraordinary new scientific instruments are churning out trailblazing data, ready to reshape how scientists view the cosmos.

A prime example is the European Space Agency’s wide-angle Euclid telescope that launched in 2023 to investigate the riddles of dark energy and dark matter.

Euclid this week delivered the first piece of a cosmic map — containing about 100 million stars and galaxies — that will take six years to create.

These stunning 3D observations may help scientists see how dark matter warps light and curves space across galaxies.

Meanwhile, on a mountaintop in northern Chile, the US National Science Foundation and Stanford University researchers are preparing to power up the world’s largest digital camera inside the Vera C. Rubin Observatory.

Trump's call for a protest crackdown has been a boon for Chinese propaganda
Analysis by CNN's James Griffiths
Protesters running amok. Innocent citizens under siege. Outside actors engaging in terrorist acts. Police struggling to maintain control and in desperate need of reinforcements.
[url=https://kra18-at.cc]kraken зеркало[/url]
That was how Chinese state media portrayed anti-government protests in Hong Kong last year, dismissing calls for greater democracy and an investigation into police brutality by focusing on individual acts of violence and property damage.
[url=https://kra18-at.cc]kra20.cc[/url]
Throughout the protests, the US was consistent in its support of people’s right to take to the streets and have their voice heard. Facing widespread unrest and public anger at home in the wake of the death of George Floyd, the reaction from US President Donald Trump appeared markedly different.
[url=https://kra18-at.cc]kra23 at[/url]
On Monday, Trump called for the military to be deployed to “dominate” protesters, and demanded states do more to stem “acts of domestic terror.”
[url=https://kra18-at.cc]кракен ссылка[/url]
The irony has not been lost on Beijing, which on Thursday marks (or rather doesn’t, the date is highly censored) its own military crackdown on anti-government protesters on June 4, 1989.
[url=https://kra18-at.cc]kra13.gl[/url]
“Washington’s promise of equality and justice for all in the country has remained hollow at best,” state news agency Xinhua said in a commentary titled “The coming suffocation of the American dream.”

“Amid the ongoing anti-racism protests in the country, decision-makers in Washington, instead of trying to sooth the pain and anger of the public, have been fanning the flames, calling protesters ‘THUGS,’ and threatening them with ‘the most vicious dogs, and most ominous weapons,” the commentary said.
kra14.at
https://kra18-at.cc
China Daily, a state-backed newspaper, noted that “The US, after the killing of Floyd, seems to be on fire, and troops have been mobilized to subdue angry demonstrators.”

“This is certainly not what the world expects to see in a country that is the world’s sole superpower,” it added. “But that sadly is the reality of the US.”

This rhetoric isn’t just embarrassing for Washington, it’s also a sign of how the US may find its influence damaged by a perceived hypocrisy over human rights at home and abroad.

Earlier today, Hong Kong’s leader Carrie Lam pointed to the unrest in the US as evidence of Washington’s “double standards.”

“They attach great importance to the national security of their country, but look at our national security through tinted spectacles, especially the current situation in Hong Kong,” she added.

The ability of Washington to influence Beijing’s position on Hong Kong – which is in part founded on fear of outside influence in the city – was already severely limited. The Trump administration’s reaction to protests at home may have hurt its position even further.
