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.

Beirut, Lebanon
CNN
—
A deadly Israeli airstrike on Hezbollah’s stronghold in southern Beirut on Friday has left over a dozen people dead, including a high-ranking Hezbollah commander, sharply escalating the conflict between the two sides and raising fears of all-out war.
[url=][/url]
Senior Hezbollah commander Ibrahim Aqil, part of Hezbollah’s elite Radwan Force, was assassinated along with “about 10” other commanders, Israel Defense Forces (IDF) spokesperson Daniel Hagari said, accusing them of planning to raid and occupy communities in Galilee in northern Israel.

Hezbollah confirmed Aqil’s death on Friday, saying he was killed “following a treacherous Israeli assassination operation on 09/20/2024 in the southern suburbs of Beirut.”

According to Hagari, the targeted commanders were “underground underneath a residential building in the heart of the Dahiyeh neighborhood, using civilians as a human shield” at the time of the attack.

Lebanon’s health ministry said at least 14 people were killed and 66 others injured in the airstrike, which leveled a multistory building in a densely populated neighborhood.

Aqil had a $7 million bounty on his head from the United States for his suspected involvement in the 1983 strike on the US Embassy in Beirut, which killed 63 people, as well as the bombing of the Beirut Marine barracks, which killed 241 US personnel later that year.

A CNN team on the ground in Beirut saw a frantic effort to rescue people from underneath the rubble and rush the wounded to hospital. Witnesses said nearby buildings shook for nearly half an hour after the strike, which the IDF said it had carried out at around 4 p.m. local time.

A week of surprise attacks
Friday’s strike marked the fourth consecutive day of surprise attacks on Beirut and other sites across the country, even as Israeli forces continued deadly strikes and operations in Gaza and the occupied West Bank.

The first major attack against Hezbollah this week came Tuesday afternoon when pagers belonging to the militant groups’ members exploded near-simultaneously. The pagers had been used by Hezbollah to communicate after the group’s leader, Hassan Nasrallah, encouraged members to switch to low-tech devices to prevent more of them from being assassinated.

Almost exactly 24 hours later, Lebanon was rocked by a second wave of explosions, after Hezbollah walkie-talkies detonated in Beirut and the south of the country on Wednesday.

At least 37 people were killed, including some children, and more than 3,000 were injured in the twin attacks.

In a United Nations Security Council meeting on Friday, UN human rights chief Volker Turk on Friday warned that the detonation of communication devices could violate international human rights law.

Lebanese Foreign Minister Abdallah Bou Habib and Israeli Ambassador to the UN Danny Danon clashed at the heated meeting, with Bou Habib calling on the council to condemn Israel’s actions and Danon slamming the Lebanese envoy for not mentioning Hezbollah.

CNN
—
Ukrainian President Volodymyr Zelensky’s visit to the White House on Thursday could be his final chance to convince a receptive American president of his country’s war aims.
[url=https://megaweb-2at.com]megaweb15.at[/url]
The precise details of the “victory plan” Zelensky plans to present in separate meetings to President Joe Biden and Vice President Kamala Harris are unknown, having been closely held until they are presented to the American leaders.

But according to people briefed on its broad contours, the plan reflects the Ukrainian leader’s urgent appeals for more immediate help countering Russia’s invasion. Zelensky is also poised to push for long-term security guarantees that could withstand changes in American leadership ahead of what is widely expected to be a close presidential election between Harris and former President Donald Trump.

The plan, people familiar with it said, acts as Zelensky’s response to growing war weariness even among his staunchest of western allies. It will make the case that Ukraine can still win — and does not need to cede Russian-seized territory for the fighting to end — if enough assistance is rushed in.

That includes again asking permission to fire Western provided long-range weapons deeper into Russian territory, a line Biden once was loathe to cross but which he’s recently appeared more open to as he has come under growing pressure to relent.

Even if Biden decides to allow the long-range fires, it’s unclear whether the change in policy would be announced publicly.

Biden is usually apt to take his time making decisions about providing Ukraine new capabilities. But with November’s election potentially portending a major change in American approach to the war if Trump were to win, Ukrainian officials — and many American ones — believe there is little time to waste.

https://megaweb-15at.com
Trump has claimed he will be able to “settle” the war upon taking office and has suggested he’ll end US support for Kyiv’s war effort.

“Those cities are gone, they’re gone, and we continue to give billions of dollars to a man who refused to make a deal, Zelensky. There was no deal that he could have made that wouldn’t have been better than the situation you have right now. You have a country that has been obliterated, not possible to be rebuilt,” Trump said during a campaign speech in Mint Hill, North Carolina, on Wednesday.

Comments like those have lent new weight to Thursday’s Oval Office talks, according to American and European officials, who have described an imperative to surge assistance to Ukraine while Biden is still in office.

As part of Zelensky’s visit, the US is expected to announce a major new security package, thought it will likely delay the shipping of the equipment due to inventory shortages, CNN previously reported according to two US officials. On Wednesday, the US announced a package of $375 million.

The president previewed Zelensky’s visit to the White House a day beforehand, declaring on the margins of the United Nations General Assembly his administration was “determined to ensure that Ukraine has what it needs to prevail in fight for survival.”
[url=https://mega555kf7lsmb54yd6etzginolhxxi4ytdoma2rf77ngq55fhfcnid.com]mega...
“Tomorrow, I will announce a series of actions to accelerate support for Ukraine’s military – but we know Ukraine’s future victory is about more than what happens on the battlefield, it’s also about what Ukrainians do make the most of a free and independent future, which so many have sacrificed so much for,” he said.
