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.

Tbilisi, Georgia — Jailed journalist Mzia Amaghlobeli gets weaker every day as her hunger strike has reached three weeks in Rustavi, a town near the Georgian capital of Tbilisi, her lawyer says. Now the 49-year-old is having difficulty walking the short distance from her cell to the room where they usually meet, and human rights officials, colleagues and family fear for her life.
[url=https://kra25-at.com]kra29 cc[/url]
Amaghlobeli was arrested Jan. 12 during an anti-government protest in the coastal city of Batumi, one of over 40 people in custody on criminal charges from a series of demonstrations that have hit the South Caucasus nation of 3.7 million in recent months.

The political turmoil follows a parliamentary election that was won by the ruling Georgian Dream party, although its opponents allege the vote was rigged.

Protests highlight battle over Georgia's future. Here's why it matters.
Its outcome pushed Georgia further into Russia's orbit of influence. Georgia aspired to join the European Union, but the party suspended accession talks with the bloc after the election.

As it sought to cement its grip on power, Georgian Dream has cracked down on freedom of assembly and expression in what the opposition says is similar to President Vladimir Putin's actions in neighboring Russia, its former imperial ruler.

Kate Winslet had a surprising ‘Titanic’ reunion while producing her latest film ‘Lee’
[url=https://kraken2trfqodidvlh4aa337cpzfrhdlfldhve5nf7njhu7instad.com]kraken... onion[/url]

Kate Winslet is sharing an anecdote about a “wonderful” encounter she recently had with someone from her star-making blockbuster film “Titanic.”

The Oscar winner was a guest on “The Graham Norton Show” this week, where she discussed her new film “Lee,” in which she plays the fashion model-turned-war photographer Lee Miller from the World War II era.

kraken2trfqodidvlh4aa337cpzfrhdlfldhve5nf7njhumwr7instad
Winslet recounted that while she had previously executive produced a number of her projects, “Lee” was the first movie where she served as a full-on producer. That required her involvement from “beginning to end,” including when the film was scored in post-production.

She explained to Norton that when she attended the recording of the film’s score in London, while looking at the 120-piece orchestra, she saw someone who looked mighty familiar to her.

“I’m looking at this violinist and I thought, ‘I know that face!’” she said.

At one point, other musicians in the orchestra pointed to him while mouthing, “It’s him!” to her, and it continued to nag at Winslet, prompting her to wonder, “Am I related to this person? Who is this person?”

Finally, at the end of the day, the “Reader” star went in to where the orchestra was to meet the mystery violinist, and she was delighted to realize he was one of the violinists who played on the ill-fated Titanic ocean liner as it sank in James Cameron’s classic 1997 film.
“It was that guy!” Winslet exclaimed this week, later adding, “it was just wonderful” to see him again.

“We had so many moments like that in the film, where people I’ve either worked with before, or really known for a long time, kind of grown up in the industry with, they just showed up for me, and it was incredible.”

“Lee” released in theaters in late September, and is available to rent or buy on AppleTV+ or Amazon Prime.
