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.

Adoro o clima alucinante de MegaPosta Casino, oferece uma aventura de cassino que detona tudo. A gama do cassino e simplesmente um estouro, incluindo jogos de mesa de cassino cheios de estilo. O atendimento ao cliente do cassino e uma verdadeira faisca, com uma ajuda que e pura energia. O processo do cassino e limpo e sem turbulencia, mesmo assim mais recompensas no cassino seriam um diferencial insano. Em resumo, MegaPosta Casino vale demais explorar esse cassino para os viciados em emocoes de cassino! De lambuja a plataforma do cassino detona com um visual que e puro gas, da um toque de classe braba ao cassino.

Je suis captive par MyStake Casino, il propose une aventure de casino qui captive comme un secret bien garde. Il y a un tourbillon de jeux de casino captivants, avec des machines a sous de casino modernes et envoutantes. L’assistance du casino est chaleureuse et perspicace, repondant en un souffle mystique. Les transactions du casino sont simples comme une rune dechiffree, cependant des recompenses de casino supplementaires feraient frissonner. Au final, MyStake Casino c’est un casino a explorer sans tarder pour ceux qui cherchent l’adrenaline secrete du casino ! En plus l’interface du casino est fluide et envoutante comme un sortilege, donne envie de replonger dans le casino sans fin.

Je suis totalement ensorcele par MyStake Casino, ca degage une ambiance de jeu aussi mysterieuse qu’un clair-obscur. La selection du casino est un voile de plaisirs, comprenant des jeux de casino adaptes aux cryptomonnaies. Les agents du casino sont rapides comme une vision prophetique, joignable par chat ou email. Les gains du casino arrivent a une vitesse ensorcelante, parfois j’aimerais plus de promotions de casino qui captivent. Globalement, MyStake Casino offre une experience de casino ensorcelante pour les joueurs qui aiment parier avec flair au casino ! En plus l’interface du casino est fluide et envoutante comme un sortilege, donne envie de replonger dans le casino sans fin.

Ich bin total begeistert von Pledoo Casino, es ist ein Online-Casino, das wie ein Wirbelwind tobt. Die Spielauswahl im Casino ist wie ein funkelnder Ozean, mit Casino-Spielen, die fur Kryptowahrungen optimiert sind. Die Casino-Mitarbeiter sind schnell wie ein Blitzstrahl, mit Hilfe, die wie ein Funke spruht. Casino-Gewinne kommen wie ein Komet, manchmal mehr Casino-Belohnungen waren ein funkelnder Gewinn. Alles in allem ist Pledoo Casino ein Casino, das man nicht verpassen darf fur die, die mit Stil im Casino wetten! Zusatzlich das Casino-Design ist ein optisches Spektakel, Lust macht, immer wieder ins Casino zuruckzukehren.

Ich bin suchtig nach Platin Casino, es ist ein Online-Casino, das wie ein Edelstein strahlt. Der Katalog des Casinos ist eine Schatzkammer voller Spa?, mit Casino-Spielen, die fur Kryptowahrungen optimiert sind. Der Casino-Kundenservice ist wie ein glanzender Edelstein, antwortet blitzschnell wie ein geschliffener Diamant. Der Casino-Prozess ist klar und ohne Schatten, dennoch mehr regelma?ige Casino-Boni waren luxurios. Insgesamt ist Platin Casino ein Casino, das man nicht verpassen darf fur die, die mit Stil im Casino wetten! Ubrigens das Casino-Design ist ein optischer Schatz, was jede Casino-Session noch glanzvoller macht.

Hey guys,

I've been checking out the world of internet gambling lately, and I’ve gotta say — it’s a total blast. At first, I was honestly suspicious. I mean, how do you even rely on an online platform with your cash, right? But after spending hours researching (and trying out a few sketchy sites so you can avoid that mess), I figured out a few things that set apart a trustworthy casino from a complete fraud. 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 UK Gambling Commission), just close that tab. No bonus is worth the trouble of never seeing your funds again. Also — and I know no one wants to — go through the small print. That’s the only way to know what kind of wagering requirements they’ve slapped onto those so-called “amazing” bonuses.

Now, let me share a site I’ve been using these last few weeks. It’s been a breath of fresh air. The interface? Super clean. Payouts? Fast as hell. And the game selection? *Massive*. Slots, live dealers, blackjack, even some weird niche games I hadn’t tried before. Check it out here: <a href="https://www.livinlite.com/forum/index.php/topic,6510.0.html">spin mama</a> . What really stood out was the help desk. 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 left hanging — yeah, not worth it.

Also, if you’re into bonuses (and who isn’t?), this place offers some legit ones. But here’s the trick: don’t just chase bonuses. It’s smarter to get reasonable terms than a huge bonus you’ll never be able to withdraw. I’m not saying you should go and blow your whole paycheck — please don’t. But if you’ve got a little extra fun budget and you’re looking for a chill way to spend an evening, online casinos can totally deliver. Just keep your head on, set a budget, 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 looking for solid info or trying to find a decent place to play. If you’ve got your own go-to sites or even some wild losses, I’m all ears — love talking shop about this stuff.

Good luck out there, and don’t let the house win too much ??
