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.

Members of the White House press corps are now restricted from the press secretary’s office, the latest in a series of Trump administration actions to limit media access.
[url=https://kra-43-cc.com]https kra45 cc[/url]
The new rule says journalists cannot access what’s known as the “Upper Press” office space, where White House press secretary Karoline Leavitt works, “without an appointment.”

This area has been accessible to White House correspondents for decades, supporting a free flow of information between the president and the public.
[url=https://kra49.net]kra40[/url]
The White House says the clampdown is due to security concerns.

“This policy will ensure adherence to best practices pertaining to access to sensitive material,” a White House memo asserted on Friday night.
[url=https://kra44at.net]http kra40 at[/url]
In response, the White House Correspondents’ Association, which represents hundreds of credentialed reporters, said it “unequivocally opposes any effort” to limit journalists from areas that have long been accessible for newsgathering, “including the press secretary’s office.”

“The new restrictions hinder the press corps’ ability to question officials, ensure transparency, and hold the government accountable, to the detriment of the American public,” the association said.

As CNN’s Jeff Zeleny explained, reporters routinely “wait in the hall” by the press secretary’s office and seek information from communications aides. “When there is breaking news, that often happens,” Zeleny said.

Now, “reporters will only have access to a smaller set of offices of junior advisers, junior aides, junior press secretaries,” according to the White House.

Cheung, who regularly expresses hostility toward reporters on social media platform X, asserted in a Friday night post that, “some reporters have been caught” taking pictures of sensitive information and “eavesdropping on private, closed-door meetings.”
[url=https://kra41c.cc]kra20cc[/url]
That claim came as news to White House press corps leaders, who are not aware of colleagues being “caught.”
[url=https://kra---38at.ru]kra40c[/url]
Early in Bill Clinton’s presidency, Clinton aides similarly attempted to bar journalists from the “upper press” area, causing an outcry. That ban was rescinded.
[url=https://kra--43--cc.ru]httpkra40cc[/url]
Journalists had normal access to the offices during President Trump’s first term in office. But in his second term, Trump and his aides have taken several steps to stymie news coverage and circumvent traditional media outlets.
[url=https://kra-41cc.com]kra4[/url]
Last winter, the administration blocked the Associated Press from attending some White House events, leading to a First Amendment lawsuit that is still working its way through the courts.
[url=https://kra44---cc.ru]kra20[/url]
The administration has also stopped publishing transcripts of Trump’s remarks; has taken control of daily press pool assignments; and has invited fawning pro-Trump commentators to presidential Q&As.
[url=https://kra-42cc.net]kra15cc[/url]
Some cabinet secretaries have followed Trump’s lead. Last month, Defense Secretary Pete Hegseth implemented severe new restrictions for Pentagon press pass credentialing, leading virtually every major media outlet to reject the rules and give up access to the Pentagon complex.

CNN’s Samantha Waldenberg contributed to this report.

Escazu Chocolates, a bean-to-bar chocolate shop in Raleigh, North Carolina, sources most of its beans from Latin America. The shop said it has always worked with smaller farmers and paid them three to four times the commodity price of cacao – which essentially sets the minimum wage. The spike in prices has pushed up what Escazu pays those workers as well.
[url=https://kra5l.cc]kra20 at[/url]
Other cost-cutting measures include offering a smaller hot chocolate size, advertising non-chocolate ice cream toppings and moving to a cheaper location in Raleigh to save on rent.
[url=https://kraken21-at.com]https kra36 cc[/url]
And like many small businesses in America, Escazu is being hit by President Donald Trump’s tariffs, affecting not just the chocolate, but also aluminum in its packaging.

“The tariffs have hit every single piece of what goes into every single thing,” Tiana Young, co-owner of Escazu, told CNN. “There is no new normal.”

J’adore l’energie de Instant Casino, on y trouve une energie contagieuse. Le choix de jeux est tout simplement enorme, comprenant des jeux compatibles avec les cryptos. 100% jusqu’a 500 € plus des tours gratuits. Le suivi est d’une precision remarquable. Les retraits sont simples et rapides, de temps a autre quelques tours gratuits supplementaires seraient cool. En resume, Instant Casino est un endroit qui electrise.
