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.

When British traders landed on India’s shores in the 1600s, they arrived in search of spices and silk but stayed for centuries – leaving behind a legacy that would shape the nation long after their colonial exploitation ended: the English language.

Over the centuries, English seeped into the very fabric of Indian life – first as a tool of commerce, then as the language of law and, eventually, a marker of privilege.

Now, after more than a decade of Hindu-nationalist rule, Prime Minister Narendra Modi’s Bharatiya Janata Party (BJP) is mounting perhaps the most significant challenge yet to the language’s place in India.

“Those who speak English will soon feel ashamed,” Home Minister Amit Shah said last month, igniting a heated debate about national identity and social mobility in the polyglot nation of 1.4 billion.

While Shah did not mention India’s former colonial masters, he declared that “the languages of our country are the jewels of our culture” – and that without them, “we cease to be truly Indian.”

Spoken behind the walls of colonial forts and offices, English in India was at first the language of ledgers and treaties.

But as British rule expanded from the ports of Gujarat to the palaces of Delhi, it became the lingua franca of the colonial elite.

At independence, India faced a dilemma. With hundreds of languages and dialects spoken across its vast landscape, its newly appointed leaders grappled with the question of which one should represent the new nation.

Hindi, the predominant language in the north, was put forward as a candidate for official language.

But strong resistance from non-Hindi-speaking regions – especially in the south – meant English would remain only as a temporary link to unite the country. It’s a legacy that endures to this day – and still rankles some.

“I subscribe to the view that English is the language of the colonial masters,” Pradeep Bahirwani, a retired corporate executive from the southern city of Bengaluru, said, adding: “Our national language should be a language which… has got roots in India.”

Ребята, всем привет! Хочу поделиться своими впечатлениями от недавней покупки частотных преобразователей. Давно планировал обновить оборудование в своей мастерской, и вот наконец-то решился. Перелопатил кучу информации, сравнил разные модели и бренды.
Что могу сказать – я просто в восторге! Установка прошла на удивление легко и быстро. Инструкция понятная, все интуитивно. Сразу после подключения почувствовал разницу. Двигатели стали работать значительно тише и плавнее. Больше нет этих раздражающих рывков и вибраций, которые были раньше.
Порадовала возможность точной настройки скорости. Теперь могу подобрать оптимальный режим работы для каждого конкретного случая. Это реально повышает производительность и качество обработки материалов. Раньше приходилось мириться с ограничениями, а сейчас - полная свобода творчества!
Это действительно инвестиция в комфорт, качество и эффективность работы. А еще хочу отметить отличную поддержку от продавца. Ответили на все мои вопросы, помогли с выбором и дали полезные советы по эксплуатации. Всем удачи и творческих успехов! - [url=https://obovsem.myqip.ru/?1-5-0-00000590-000-0-0-1749561220]Частотный преобразователь 1.5 кВт[/url]

Hey guys,

I've been diving into the world of internet gambling lately, and I’ve gotta say — it’s way more exciting than I expected. At first, I was honestly suspicious. I mean, how do you even believe in an online platform with your cash, right? But after testing the waters (and trying out a few sketchy sites so you won’t have to), I figured out a few things that set apart a trustworthy casino from a total scam. First off, if you’re new to all this, here’s the golden rule: **licenses matter**. If a casino doesn’t have a proper regulatory certificate (like from the MGA or the UKGC), just run. No bonus is worth the trouble of never seeing your money again. Also — and I know no one wants to — check the terms. That’s the only way to know what kind of wagering requirements they’ve slapped onto those so-called “juicy” bonuses.

Now, let me share a site I’ve been playing on these last few weeks. It’s been a total win. The interface? Super clean. Payouts? No waiting around. And the game selection? *Insane*. Slots, live dealers, blackjack, even some weird niche games I hadn’t tried before. Check it out here: <a href="https://www.hostboard.com/forums/showthread.php?t=1175344&p=2900229#post... mama promo code</a> What really impressed me was the customer service. I had a tiny issue with a bonus not working, and they got back to me in like instantly. Compare that to other sites where you’re just shouting into the void — yeah, no thanks.

Also, if you’re into bonuses (and who isn’t?), this place offers some juicy ones. But here’s the trick: don’t just go crazy over promos. It’s smarter to stick to reasonable terms than a huge bonus you’ll never be able to withdraw. I’m not saying you should go and bet the farm — please don’t. But if you’ve got a little extra cash and you’re looking for a bit of online excitement, online casinos can totally deliver. Just keep your head on, control your bankroll, and don’t treat it like a side hustle. It’s for fun, not for a paycheck. Anyway, just wanted to drop my experience here in case anyone’s curious or trying to find a decent place to play. If you’ve got your own go-to sites or even some horror tales, I’m all ears — love talking shop about this stuff.

Good luck out there, and spin smart, win big ??
