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.

Le processus du casino est transparent et sans fausse note, par moments des recompenses de casino supplementaires feraient chanter. Pour resumer, Unibet Casino offre une experience de casino envoutante pour ceux qui cherchent l’adrenaline rythmee du casino ! Par ailleurs la navigation du casino est intuitive comme une partition, facilite une experience de casino enchanteresse.

Equipos de balanceo: indispensables para el rendimiento fluido y confiable de las maquinas

En el mundo de la innovacion tecnologica, donde la optimizacion y la seguridad operativa del equipo son de relevancia critica, los equipos de balanceo desempenan un funcion esencial. Estos herramientas avanzadas estan disenados para equilibrar y estabilizar partes rotativas, ya sea en planta productiva, medios de transporte o incluso en electrodomesticos.

Para los tecnicos de servicio y los expertos en ingenieria, trabajar con tecnologias de equilibrado es indispensable para asegurar el funcionamiento suave y fiable de cualquier mecanismo giratorio. Gracias a estas herramientas modernas de balanceo, es posible reducir significativamente las vibraciones, el ruido y la presion en los rodamientos, extendiendo la duracion de elementos caros.

Igualmente crucial es el papel que ejercen los equipos de balanceo en la atencion al cliente. El soporte tecnico y el servicio periodico utilizando estos sistemas garantizan resultados superiores, mejorando la experiencia del usuario.

Para los empresarios, la implementacion en plataformas de equilibrado y monitoreo puede ser determinante para aumentar la capacidad y resultados de sus equipos. Esto es especialmente critico para los directivos de pymes, donde toda mejora es significativa.

Ademas, los equipos de balanceo tienen una amplia aplicacion en el sector del monitoreo tecnico. Ayudan a prever problemas, ahorrando gastos elevados y danos a los equipos. Mas aun, los resultados extraidos de estos sistemas pueden utilizarse para mejorar la produccion.

Las industrias objetivo de los equipos de balanceo se extienden a muchos sectores, desde la industria ciclista hasta el control del medioambiente. No importa si se trata de plantas manufactureras o pequenos talleres caseros, los equipos de balanceo son necesarios para garantizar un desempeno estable y continuo.
