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.

Availability

<p>As well as others, Coin Mixer has both a clear-web CryptoMixer. This mixing service is notable for accommodating extremely large-volume transactions. After public verification of their reserve of 2000 BTC there is no doubt that users can trust this mixing service and their cryprocurrencies will not be taken. The number of needed confirmations differs depending on the deposited amount, e.g. for depositing less that 25 BTC there is only 1 confirmation needed, in case of sending more than 1000 BTC a user needs to gather 5 confirmations. To use this platform, a Coin Mixer code needs to be created. A user should note it, so it is easy to use it next time. After entering a CryptoMixer code, users need to provide the output address or several of them and then set a time-delay feature. A delay time is determined automatically and a user can modify it if needed. A service fee can be also selected from the table depending on the sent sum. Each transaction requires additional fee of 0.0005 BTC. Also, a calculator on the main page helps every user to see the amount of crypto money sent and got back after mixing.</p><br><ul> <li><a href=https://yomix9.com/>Yomix</a> : Uses stealth pools to anonymize transactions </li> <li>Coin Mixer : Fast payouts </li> <li>Bitcoin Mixer : It offers flexible transaction fees and a low minimum transaction limit</li> <li>Mixero : Excellent customer support </li> <li>Coinmize : Zero-log policy </li> </ul><br><br><h2 id=menu1>1. Yomix - Uses stealth pools to anonymize transactions </h2><p>It is a simple service with a high level of anonymity. The Yomix mixing process is very simple and only takes a couple of minutes. You need to select one of the three supported cryptocurrencies (Bitcoin, Litecoin, Bitcoin Cash), enter the withdrawal address, set the transaction delay for any time up to 72 hours, send the coins to the specified address and wait for their delivery to the destination. This site is unlike the other three mixing pools. You can mix user’s coins: with incoming coins of other customers, private reserves of the service and investor coins. The service does not require registration. The mixing commission is not large and is taken from the mining commission, which is very convenient. The referral program at SmartMixer is one of the most profitable, during the first mixing operation you receive a smart code that is required to receive a discount on the commission, this discount can reach – 70%. After each transaction, the user receives a letter of guarantee. All data about it is deleted after a day, while maintaining the complete anonymity of the client.Another coin scrambler Mixtum offers you a so-called free trial period what means that there are no service or transaction fee charged. The process of getting renewed coins is also quite unique, as the tumbler requires a request to be sent over Tor or Clearnet and renewed coins are acquired from stock exchanges.Yomix works by removing the link between your old and current addresses. Since the mixer destroys any connection between them, your traces of transactions and your identity become untraceable. The main advantage is the low commission. Bitcoin Laundry is a donation platform. They charge no service fees, only a transaction fee of 0.0002 BTC to the exit address, while transactions from 0.0005 to 38 BTC are supported. You can set 5 addresses and specify what percentage of the total amount will be returned to each address. You can select predefined or random payment delays for each address, making it even more difficult to track the transaction. Bitcoin Laundry boasts a “no log” retention period policy and also allows users to manually delete logs with just one click if they wish.This particular Yomix supports Bitcoin cryptocurrency and does not bear any logs policy. It requires a minimum deposit of 0.01 BTC and the transaction fee is 1–3%. It supports multiple addresses of up to 10 and requires confirmation. No registration is required and it does offer a referral program.</p><p> Pros: <ul><li>No logs</li><li>Provides user-controlled time delays </li></ul></p> <h2 id=menu2>2. Coin Mixer - Fast payouts </h2><p>Coin Mixer is unique in the sense that it offers support for both Bitcoin and Ethereum. The site does not require registration and has a minimum deposit requirement of 0.2 BTC. Transaction fees range from 2 – 5% depending on the amount that is being transferred. There is no referral program offer for Coin Mixer and multiple addresses are not supported. Finally, letters of guarantee are not provided.Grams itself is a brand on the Darknet so I believe not much needs to be said about it. Grams Helix is one of its subsidiaries and is one of the most reputed and widely used Coin Mixer services out there, it’s simple, modern, and definitely trustworthy. Grams supports only Bitcoins for now. It needs 2 confirmations before it cleans and sends you your coins. It obviously supports time-delay, but it’s automatically set to “2 hours” for some reasons. It also supports “Random transactions” for the deposit, the deposit address changes after each transaction and allows you to send more than 1 transactions to Grams Helix instead of sending in all your coins in a single go. The same is also supported for the “output addresses” (where you receive coins) and you can input as many as 5 different BTC addresses where your coins are sent after cleaning them. The coin-deposit address is valid for 8 hours, and any transaction not done within these 8 hours won’t be received by the platform.Coin Mixer is one of those mixing services that keep your crypto safe. The platform will take your bitcoin, mix it with other deposits, and give you the same amount of bitcoin in return. It’s designed to reduce bitcoin tracking, “clean” your coins, and help ensure anonymity on the transparent bitcoin network. A bitcoin mixer service like BitMix.Biz will take your bitcoin, then give you different bitcoin in return. The platform collects everyone’s bitcoin deposits, mixes them up into one central account, and then returns the bitcoins to users. You get the same amount of bitcoin (minus a fee), but different bitcoin from different parts of the blockchain. With BitMix.Biz, you get a letter of guarantee. That letter of guarantee is proof of BitMix.Biz’s obligations. When they give you their bitcoin address, they’ll provide a digitally-signed confirmation that this address has genuinely been generated by the server. That letter is always signed from the BitMix.Biz main bitcoin account (that account is publicly available on BitMix.Biz). The platform also uses a special 12 symbol “code” to ensure you get your bitcoin back every time you use the service. You save that code. That code also 100% excludes you from receiving your own coins anytime in the future. With Coin Mixer you will get: Fully Anonymity After your order is invalid, BitMix.Biz will remove any information about your transactions. Absolutely no logs or personality identifying information is kept regarding your use of the BitMix.Biz service. Instant Transfer Money is instantly transferred to your address after your transaction is confirmed. Partner Program Coin Mixer pays users when they refer others to the platform. They’ll pay for every transaction made by an invited user. The platform charges a mining fee of 0.4 to 4%. You can set the fee manually when you’re mixing your bitcoins. The address fee is 0.0005 BTC per output address to cover any transaction fees charged by miners. BitMix.Biz’s mixing process takes up to 24 hours, although it’s usually “almost instant” depending on the current service load. You’re required to mix a minimum of 0.007 BTC and a maximum of 1000 BTC. Transactions outside this range will not be accepted.Coin Mixer is being listed at the #1 spot here, well that’s not without substance. The top reasons why I’m in love with this Bitcoin tumbler is because it’s fast, takes care of our anonymity and privacy, and has a very negligible fee. Smartmix bitcoin mixing service The payout is almost instant, all it needs is 2 confirmations for the dirty coins being sent in to be cleaned or tumbled. No account needs to be created to clean your coins either. They have advanced options which let you set “delayed payouts” which further increase your anonymity and make it hard to link the coins going inside to the coins coming out. There’s even an option to add up to 5 addresses, so your coins are broken down into 5 different parts and sent to the different addresses again adding another layer of anonymity. The minimum amount too is pretty low being just 0.001BTC while the maximum limit is 15.32BTC. It’s pocket-friendly as well, with the fee being just 0.5% per mix + 0.0001BTC/address, in fact, it probably is one of the lowest fee in the industry altogether. As for anonymity, they delete all logs related to your mix after 7 days which finally erases the last thread which could ever be linked back to you. So yes, enough reasons to list it at the #1 spot, don’t you agree?</p><p> Pros: <ul><li>It offers flexible transaction fees and a low minimum transaction limit</li><li>Customizable mixing settings for better anonymity</li></ul></p> <h2 id=menu3>3. Bitcoin Mixer - It offers flexible transaction fees and a low minimum transaction limit</h2><p>Bitcoin Blender isn’t as heavily decorated as Bitcoin Mixer, as far as the webpage design goes. But the services and reviews are in no way less as compared to any of the top Bitcoin Tumbler services on the web. It’s a service functional since 2014, and offers two different kind of accounts: Quickmix: Requires no login, but offers lesser control Login enabled account: Requires you to login, provides for more control than the quickmix account. The mixing service is only accessible from its Onion URL, and even though it has a clearnet URL, it primarily only serves an educational purpose. It’s exclusively a Bitcoin mixing service, and supports only Bitcoin. As for the fee, it doesn’t have anything specific, and charges a random fee between 1-3%. This is done to keep our Bitcoins anonymous and more secure, rather than tagging them with a specific fee. Although there’s a special program, or incentive so to say, if amounts worth more than 10 BTC are deposited within a time-frame of 7 days, the fee is reduced by half! Obviously, there also is the time-delay feature, allowing us to delay the transaction by as much as 24 hours. As for security, it supports 2-factor authentication, facilitated with a customized PGP key which ensures only the holder of the PGP key along with the knowledge of the password can access your accounts. It also supports as many as 5 simultaneous deposit addresses, which get you the power to deposit unmixed funds by splitting them into more than one single transaction. And finally, there’s a no logs policy as well, and all the data including deposit addresses and support messages are deleted after 10 days.Bitcoin Mixer is yet another simple yet trustworthy Bitcoin Tumbler service. And one of the primary differences it has compared to the other platforms on this list is that it can accommodate really “large volume transactions”. Their claims to have Bitcoin reserves of over 2000BTC has been verified publicly (source: https://bitcointalk.org/generator.php?topic=1484009.msg15350012#msg15350012) so that also makes sure they won’t be running away with our Bitcoins and adds to their credibility. As for the mixing services, the receiving time is instant. Also, they’re pretty trusting and need only the following confirmations: <25BTC= 1 Confirmations. 25-250BTC=3 Confirmations. 250-1000BTC= 4 Confirmations. 1000+ BTC= 5 Confirmations. The receiving addresses have a validity of 24 hours, within which the payment has to be made. There is no Maximum transaction limit as such, considering how their reserve is really huge and you’ll need to be a millionaire before you can run them out of funds, and if any limit as such is involved, you’re notified during the process itself before you make the payments. The minimum transaction limit is 0.001BTC, anything lower than this is again considered donations like in the case of PriveCoin and isn’t sent out to the customer. As for the fee, their minimum fee is 0.5% (pretty low, huh?) with an additional 0.0005BTC for every deposited transaction. Although it varies for different amounts as the screenshot below explains: Also, it offers us additional control, by letting us control how much % of the Bitcoins will be sent in 1 transaction to one wallet address. Needless to mention, you can set a custom fee for added anonymity and they also provide a letter or guarantee like all the mentionable Bitcoin Tumblers out there.Bitcoin Mixer currently only supports Bitcoin mixes, however, it has plans to bring in ETH mixes in the near future. It has been featured on Bitcoin.com/ News BTC/ Crypto News/ The Next Web etc. hence building a bit of trust. Very modern, advanced, user-controlled interface. Allows upto 5 output addresses. Obviously, doesn’t keep any logs whatsoever. The user-control is impressive. You get to control the fund-distribution, as well as the time-delay for each output address manually. Even the fee can be set manually. The cheapest allowed fee is 0.5% which is more than acceptable. The highest is set at 5%. Obviously the 0.25mBTC blockchain transaction fee is attached on top of the selected fee. It even has a “strength meter” which shows how strong your mix is, based on all the factors you’ve selected. No registration required whatsoever. And it does provide the mixing code to ensure all outputs are fresh and not linked to any of your previous deposits.Bitcoin Mixer is a very impressive service if you want to maintain your anonymity when you make purchases online. It can also be useful if you want to do p2p payments and donations. The service is used to mix a person’s funds and give this person some fresh bitcoins. The focus here is on making sure that the blender has the ability to confuse the trail as somebody could try to figure out the source. The best mixer is that one that keeps your anonymity at a max. You want each bitcoin transaction to be very hard to trace. This is where using our bitcoin mixing service makes a lot of sense. Protect your income and personal information becomes much easier. The reason why you want to use our service is because you want to hide your coins from hackers and third-parties. They can do a blockchain analysis, they may be able to track your personal data to steal your bitcoins. With our bitcoin tumbler, you don’t have to worry about that anymore.</p><p> Pros: <ul><li>It has a positive reputation among the Bitcoin community</li><li>Excellent customer support </li></ul></p> <h2 id=menu4>4. Mixero - Excellent customer support </h2><p>Two cryptocurrencies are also supported on Mixero mixing service. This scrambler is listed because it works quickly and it is reliable. The transaction fee is really low, only the amount of 0.0001 BTC needs to be sent for every extra address. Splitting deposited coins between 5 addresses is also extremely helpful for keeping user’s anonymity. Every user is able to choose an additional option of delaying the payment meaning that the transaction is becoming even more anonymous.How it works: it has its own cryptocurrency reserve, which can be represented as a chain of bitcoins. When you transfer your funds to the Blender io, the resource sends your funds to the end of the chain and sends you new coins from the beginning of the chain that have nothing to do with the old coins. therefore, there can be no connection between incoming and outgoing coins. Only coins that go from your wallet to the Mixero address can be tracked through the public ledger, but no further. Blender io does not require you to register or provide any information other than the “receiving address“! It does not require identity confirmation and registration, but it is mandatory to provide in addition to the “receiving address”. The additional withdrawal delay feature has been extended to the maximum and offers installation up to 24 times a day. Other servers do not have such a wide range of latencies. Each set of unrefined coins can be split into as many as 8 pieces and sent to different addresses with an additional fee of 0.00008 BTC per address.Mixero bitcoin mixer is one of the few that allows large-volume transactions. The minimum size for a mixing operation is 0.001 BTC, any amount below this level is considered a donation and is not sent back to the client, there is no maximum transfer limit. The minimum commission is 0.5% with an additional fee of 0.0005 BTC for each incoming transaction. During the transaction, you will receive a letter of guarantee, as in all previously mentioned mixers.Mixing Bitcoins is made simpler with Mixero. A mixer available both on the Clearnet and the Tor network. Offers complete control over the time-delays and fund-distribution. Charges a static fee of 0.3%. Maximum number of output addresses allowed is 10. Each address is charged an additional 0.0001BTC. Largest possible mix is 100 BTC, while smallest accepted deposit is 0.002 BTC. No registration required. Has a No Logs Policy, retains logs for 7-days by default. Although users can delete logs anytime before the 7-day period manually. Does provide Certificate of Origin. Also has an “Instant Dispatch” feature of delivering coins without any delay.</p><p> Pros: <ul><li>Uses stealth pools to anonymize transactions </li><li>Excellent customer support </li></ul></p> <h2 id=menu5>5. Coinmize - Zero-log policy </h2><p>Coinmize is a btc shuffle service needed to hide your transfers in the bitcoin world. Coinmize currently has a minimum withdrawal threshold of 0.03500000 BTC, so users are advised to deposit more than the entry threshold plus commission, otherwise they will not be able to withdraw funds. The client is asked to set 5 exit addresses. If for some reason, even after a delay of two hours, the user’s balance is not updated, the mixer can contact the support service to take action. For customers who have been inactive for several days, it can take up to 15 minutes after logging in before you see outstanding deposits. Transaction histories are automatically deleted within 1 week after that. The program runs on a dedicated server that is openly connected via the Internet (you don’t need to do this when using the Tor browser). The Bitcoin mixer is launched on another machine, all suspicious activity is monitored, and the website is automatically protected in case of any indication that it is under DDoS attack.Compared to other Bitcoin tumblers, Coinmize stands out from the crowd thanks to the additional anonymity offered. Users are given the option to split and merge coins into different wallets to various addresses. Additionally, Coinmize provides support for unlimited addresses and does not require user registration. Although only Bitcoin is supported and there are no referral programs, ChipMixer does not charge users with any service fees. With the option to donate BTCs being made available.Coinmize is a Bitcoin cleaner, tumbler, shifter, mixer and a lot more. It has a completely different working principal than most other mixers on this list. So, it has two different reserves of coins, one for Bitcoin and the other for Monero. It cleans coins by converting them to the other Cryptocurrency. So, you can either clean your Bitcoins and receive Monero in return, or vice-versa. The interface is pretty straight-forward. You simply choose your input and output coins, and enter your output address. For now, only 1 output address is supported which we believe simplifies things. The fee is fixed which further makes it easier to use. You either pay 0.0002 BTC when converting BTC to XMR, or 0.03442 XMR when converting XMR to BTC. It also provides a secret key which can be used to check transaction status, or get in touch with support. The process doesn’t take long either, Coinmize only demands 1 confirmation before processing the mixes. Bitcoin amounts as low as 0003BTC and XMR as low as 0.05 can be mixed. It doesn’t require any registrations so obviously there’s no KYC. The company seems to hate the govt. and has a strict no-log policy as well.Bitcoin Blender isn’t as heavily decorated as Coinmize, as far as the webpage design goes. But the services and reviews are in no way less as compared to any of the top Bitcoin Tumbler services on the web. It’s a service functional since 2014, and offers two different kind of accounts: Quickmix: Requires no login, but offers lesser control Login enabled account: Requires you to login, provides for more control than the quickmix account.
