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.

Dispositivos de equilibrado: indispensables para el funcionamiento optimo y estable de las maquinas

En el entorno de la innovacion tecnologica, donde la eficiencia y la fiabilidad del equipo son de maxima importancia, los sistemas de equilibrado desempenan un rol decisivo. Estos instrumentos tecnicos estan creados con el fin de equilibrar y estabilizar partes rotativas, ya sea en equipos industriales, medios de transporte o incluso en electrodomesticos.

Para los especialistas en maquinaria y los ingenieros, trabajar con tecnologias de equilibrado es indispensable para mantener el funcionamiento suave y fiable de cualquier equipo con partes en movimiento. Gracias a estas innovaciones en equilibrado, es posible reducir significativamente las oscilaciones, el ruido y la carga sobre los cojinetes, aumentando la resistencia de componentes costosos.

Igualmente relevante es el papel que tienen los equipos de balanceo en la relacion con los usuarios. El mantenimiento especializado y el mantenimiento regular utilizando estos sistemas permiten ofrecer soluciones confiables, aumentando la experiencia del usuario.

Para los propietarios, la apuesta en equipos de calibracion y sensores puede ser determinante para elevar la capacidad y resultados de sus equipos. Esto es especialmente relevante para los administradores de negocios medianos, donde toda mejora es significativa.

Ademas, los equipos de balanceo tienen una gran utilidad en el ambito de la prevencion y aseguramiento. Sirven para identificar defectos, ahorrando gastos elevados y averias graves. Mas aun, los datos obtenidos de estos sistemas sirven para optimizar procesos.

Las posibilidades de uso de los equipos de balanceo abarcan diversas industrias, desde la industria ciclista hasta el seguimiento ecologico. No importa si se trata de plantas manufactureras o negocios familiares, los equipos de balanceo son imprescindibles para garantizar un desempeno estable y continuo.

Der Casino-Service ist zuverlassig und strahlend, sorgt fur sofortigen Casino-Support, der verblufft. Casino-Gewinne kommen wie ein Komet, aber mehr regelma?ige Casino-Boni waren ein Knaller. Kurz gesagt ist PlayJango Casino ein Casino mit einem Spielspa?, der wie ein Feuerwerk knallt fur die, die mit Stil im Casino wetten! Nebenbei die Casino-Plattform hat einen Look, der wie ein Blitz funkelt, Lust macht, immer wieder ins Casino zuruckzukehren.

Elusive shipwreck found in Lake Michigan over 100 years after sinking
[url=https://rutorforum.net]rutor9 com[/url]
A “ghost ship” that sank in Lake Michigan nearly 140 years ago and eluded several search efforts over the past five decades has been found, according to researchers with the Wisconsin Underwater Archeology Association.

The wooden schooner got caught in a storm in the dead of night and went down in September 1886. In the weeks after, a lighthouse keeper reported the ship’s masts breaking the lake surface, and fishermen caught pieces of the vessel in their nets. Still, wreck hunters were unable to track down the ship’s location — until now.

Earlier this year, a team of researchers with the Wisconsin Underwater Archeology Association and Wisconsin Historical Society located the shipwreck off the coastal town of Baileys Harbor, Wisconsin, the association announced on Sunday.

Named the F.J. King, the ship had become a legend within the Wisconsin wreck hunter community for its elusive nature, said maritime historian Brendon Baillod, principal investigator and project lead of the discovery.

“We really wanted to solve this mystery, and we didn’t expect to,” Baillod told CNN. “(The ship) seemed to have just vanished into thin air. … I actually couldn’t believe we found it.”

The wreck is just one of many that have been found in the Great Lakes in recent years, and there are still hundreds left to be recovered in Lake Michigan alone, according to Baillod.

The ‘ghost ship’
Built in 1867, the F.J. King plied the waters of the Great Lakes for the purpose of trans-lake commerce. The ship transported grains during a time when Wisconsin served as the breadbasket of the United States. The 144-foot-long (44-meter) vessel also carried cargo including iron ore, lumber and more.

The ship had a lucrative 19-year career until that September night when a gale-force wind caused its seams to break apart, according to the announcement. The captain, William Griffin, ordered the crew to evacuate on the ship’s yawl boat, from where they watched the F.J. King sink, bow first.
