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.

Je suis fou de Riviera Casino, on dirait une escapade glamour au bord de la mer. Le repertoire du casino est un port de plaisirs luxueux, proposant des slots de casino a theme mediterraneen. Les agents du casino sont rapides comme un hors-bord, offrant des solutions claires et instantanees. Les gains du casino arrivent a une vitesse de yacht, par moments j’aimerais plus de promotions de casino qui eblouissent comme le soleil. Au final, Riviera Casino promet un divertissement de casino scintillant pour les passionnes de casinos en ligne ! Par ailleurs le site du casino est une merveille graphique ensoleillee, donne envie de replonger dans le casino sans fin.

Je suis totalement envoute par Stake Casino, ca degage une ambiance de jeu aussi brulante qu’une lave en fusion. Le repertoire du casino est un magma de divertissement, proposant des slots de casino a theme explosif. Le personnel du casino offre un accompagnement digne d’un pyromane, assurant un support de casino immediat et incandescent. Le processus du casino est transparent et sans cendres, par moments des recompenses de casino supplementaires feraient tout peter. Pour resumer, Stake Casino c’est un casino a explorer sans tarder pour les pyromanes du casino ! Par ailleurs la plateforme du casino brille par son style explosif, ce qui rend chaque session de casino encore plus enflammee.

Acho simplesmente animal SambaSlots Casino, parece uma festa carioca cheia de energia. Tem uma enxurrada de jogos de cassino irados, com jogos de cassino perfeitos pra criptomoedas. A equipe do cassino entrega um atendimento que e puro carnaval, respondendo mais rapido que um tamborim. Os pagamentos do cassino sao lisos e blindados, porem mais recompensas no cassino seriam um diferencial insano. Em resumo, SambaSlots Casino oferece uma experiencia de cassino que e puro batuque para os viciados em emocoes de cassino! Vale dizer tambem a plataforma do cassino brilha com um visual que e puro ritmo, adiciona um toque de axe ao cassino.
