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.

Sou louco pela torcida de MarjoSports Casino, tem um ritmo de jogo que vibra como um apito. As opcoes sao ricas e vibram como torcidas. oferecendo sessoes ao vivo que marcam como gols. Os agentes sao rapidos como um contra-ataque. garantindo suporte direto e sem impedimentos. Os pagamentos sao seguros e fluidos. entretanto mais recompensas fariam a torcida pular. No geral, MarjoSports Casino e uma rede de adrenalina para os cacadores de vitorias em gol! Vale dizer a plataforma marca gol com um visual vibrante. dando vontade de voltar como um craque.

Curto demais a quadra de MarjoSports Casino, parece um estadio lotado de adrenalina. Os jogos formam uma quadra de diversao. oferecendo lives que explodem como penaltis. O suporte e um apito preciso. garantindo suporte direto e sem impedimentos. Os saques sao velozes como um sprint final. mesmo assim mais recompensas fariam a torcida pular. Para encurtar, MarjoSports Casino e uma rede de adrenalina para os exploradores de jogos online! Vale dizer o site e uma obra-prima de estilo esportivo. adicionando um toque de drible ao cassino.

Je suis charme par Simsinos Casino, ca degage une ambiance de jeu aussi coloree qu’un studio d’animation. Il y a une cascade de jeux de casino captivants. comprenant des jeux de casino adaptes aux cryptomonnaies. Le personnel du casino offre un accompagnement digne d’un scenariste. joignable par chat ou email. se deroulent comme une rhapsodie de dessins. occasionnellement plus de tours gratuits au casino ce serait cartoon. Dans l’ensemble, Simsinos Casino est un joyau pour les fans de casino pour les animateurs du casino! A noter la navigation du casino est intuitive comme une bulle. amplifie l’immersion totale dans le casino.

Galera, nao podia deixar de comentar no 4PlayBet Casino porque me impressionou bastante. A variedade de jogos e surreal: slots modernos, todos funcionando perfeito. O suporte foi amigavel, responderam em minutos pelo chat, algo que faz diferenca. Fiz saque em Bitcoin e o dinheiro entrou muito rapido, ponto fortissimo. Se tivesse que criticar, diria que seria legal torneios de slots, mas isso nao estraga a experiencia. No geral, o 4PlayBet Casino e completo. Recomendo sem medo.

Galera, resolvi contar como foi no 4PlayBet Casino porque me impressionou bastante. A variedade de jogos e bem acima da media: poquer estrategico, todos sem travar. O suporte foi eficiente, responderam em minutos pelo chat, algo que vale elogio. Fiz saque em Bitcoin e o dinheiro entrou sem enrolacao, ponto fortissimo. Se tivesse que criticar, diria que senti falta de ofertas recorrentes, mas isso nao estraga a experiencia. Pra concluir, o 4PlayBet Casino e parada obrigatoria pra quem gosta de cassino. Eu ja voltei varias vezes.
