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.

Hey guys,

I've been diving into the world of internet gambling lately, and I’ve gotta say — it’s pretty damn addictive. At first, I was a bit wary. I mean, how do you even rely on an online platform with your cash, right? But after doing a ton of research (and trying out a few questionable sites so you don’t have to), I figured out a few things that separate a trustworthy casino from a risky mess. First off, if you’re new to all this, here’s the golden rule: **regulation is key**. If a casino doesn’t have a proper license (like from the Malta Gaming Authority or the UKGC), just close that tab. No bonus is worth the gamble 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 hooked on these last few weeks. It’s been a breath of fresh air. The interface? Super smooth. Payouts? Quick — like 24 hours quick. And the game selection? *Wild*. Slots, live dealers, blackjack, even some unique stuff I hadn’t tried before. Check it out here: <a href="https://www.diigo.com/item/note/b8j3v/arsd?k=5366d34809013ef028a5f09d6bb... game online</a> . What really impressed me 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 shouting into the void — yeah, hard pass.

Also, if you’re into bonuses (and who isn’t?), this place offers some awesome ones. But here’s the trick: don’t just grab every shiny offer. It’s smarter to stick to fair 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 play smart, 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 interested or trying to find a decent place to play. If you’ve got your own stories or even some casino nightmares, I’m all ears — love talking shop about this stuff.

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

Hey people,

I've been exploring the world of internet gambling lately, and I’ve gotta say — it’s surprisingly fun. At first, I was a bit wary. I mean, how do you even believe in an online platform with your cash, right? But after digging deep (and trying out a few dodgy sites so you don’t have to), I figured out a few things that distinguish a legit 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 Malta Gaming Authority or the UK Gambling Commission), just walk away. No bonus is worth the trouble of never seeing your funds again. Also — and I know no one wants to — check the terms. That’s the only way to know what kind of hidden traps they’ve slapped onto those so-called “juicy” bonuses.

Now, let me share a site I’ve been hooked on these last few weeks. It’s been a game-changer. The interface? Super clean. Payouts? Fast as hell. And the game selection? *Wild*.

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 drop your rent money — please don’t. But if you’ve got a little extra fun budget and you’re looking for a bit of online excitement, online casinos can totally deliver. Just stay sharp, 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 interested or trying to find a good 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.

Hey everyone,

No bonus is worth the gamble of never seeing your funds again. Also — and I know no one wants to — read the T&Cs. That’s the only way to know what kind of playthrough limits they’ve slapped onto those so-called “generous” bonuses.

Now, let me share a site I’ve been playing on these last few weeks. It’s been a game-changer. The interface? Super easy to navigate. Payouts? No waiting around. 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://mb.boardhost.com/minecraft/msg/1752405511.html">plinko casino</a> . What really won me over was the support team. I had a tiny issue with a bonus not working, and they got back to me in like 10 minutes. 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 awesome ones. But here’s the trick: don’t just chase bonuses. It’s smarter to stick to fair 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 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.
