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.

Maquinas de equilibrado: esenciales para el rendimiento fluido y confiable de las maquinas

En el entorno de la ingenieria actual, donde la eficiencia y la confiabilidad del equipo son de relevancia critica, los equipos de balanceo desempenan un papel crucial. Estos dispositivos especializados estan destinados a ajustar y mantener estables partes rotativas, ya sea en maquinaria industrial, vehiculos de transporte o incluso en equipos domesticos.

Para los tecnicos de servicio y los expertos en ingenieria, trabajar con tecnologias de equilibrado es fundamental para garantizar el rendimiento estable y confiable de cualquier sistema rotativo. Gracias a estas soluciones tecnologicas avanzadas, es posible minimizar de forma efectiva las vibraciones, el sonido no deseado y la carga sobre los cojinetes, prolongando la vida util de componentes costosos.

Igualmente crucial es el impacto que tienen los equipos de balanceo en la relacion con los usuarios. El mantenimiento especializado y el servicio periodico utilizando estos sistemas permiten ofrecer resultados superiores, mejorando la experiencia del usuario.

Para los propietarios, la implementacion en plataformas de equilibrado y monitoreo puede ser clave para elevar la eficiencia y productividad de sus equipos. Esto es especialmente critico para los empresarios que gestionan pequenas y medianas empresas, donde cada detalle cuenta.

Ademas, los equipos de balanceo tienen una gran utilidad en el campo de la seguridad y el control de calidad. Ayudan a prever problemas, previniendo danos financieros y fallos mecanicos. Mas aun, los informes generados de estos sistemas se aplican para optimizar procesos.

Las posibilidades de uso de los equipos de balanceo abarcan diversas industrias, desde la fabricacion de bicicletas hasta el seguimiento ecologico. No importa si se trata de grandes producciones industriales o negocios familiares, los equipos de balanceo son imprescindibles para asegurar un funcionamiento eficiente y sin interrupciones.

Ich finde absolut verruckt NV Casino, es pulsiert mit einer elektrisierenden Casino-Energie. Die Casino-Optionen sind vielfaltig und mitrei?end, mit einzigartigen Casino-Slotmaschinen. Die Casino-Mitarbeiter sind schnell wie ein Falke, mit Hilfe, die wie ein Funke spruht. Casino-Transaktionen sind simpel wie ein Sonnenstrahl, dennoch die Casino-Angebote konnten gro?zugiger sein. Am Ende ist NV Casino ein Casino mit einem Spielspa?, der wie ein Feuerwerk knallt fur die, die mit Stil im Casino wetten! Nebenbei die Casino-Navigation ist kinderleicht wie ein Windhauch, was jede Casino-Session noch aufregender macht.

Sou louco pelo batuque de RioPlay Casino, tem uma vibe de jogo tao animada quanto um desfile na Sapucai. O catalogo de jogos do cassino e uma folia total, com slots de cassino tematicos de festa. O suporte do cassino ta sempre na ativa 24/7, respondendo mais rapido que um batuque. Os ganhos do cassino chegam voando como um mestre-sala, mas mais bonus regulares no cassino seria um arraso. Resumindo, RioPlay Casino garante uma diversao de cassino que e uma folia total para os viciados em emocoes de cassino! E mais a interface do cassino e fluida e vibrante como uma escola de samba, eleva a imersao no cassino ao ritmo do tamborim.

Many legal bookmakers inhabit in Internet and are managed on the Internet from jurisdictions that are not related to the clients they serve, as usual, to circumvent various laws on gambling (like act on combating illegal gambling via the World Wide Web from 2006 year in USA) in selected markets, like Las Vegas, [url=https://pwadowicki.info.pl/trusted-online-casinos-with-fair-6-2/]https:/... or conducting gambling cruises on their own.- service kiosks.
