Alimentador desgasta en exceso el filamento

Posted · Alimentador desgasta en exceso el filamento

Buenos dias, 

Estoy teniendo un problema con mi impresora Ultimaker 3 extended, y me estoy empezando a desesperar, espero que podáis echarme una mano. 

El problema surge cuando imprimo piezas grandes ( a partir de 3-4 horas), el feeder empieza a desgastar el filamento hasta que finalmente queda inservible y no es capaz de seguir circulando hasta el extrusor, por lo tanto el flujo de filamento es menor del que debería y termina imprimiendo algo similar a un nido de pájaro, donde las lineas son mucho mas estrechas de lo que deberían, generando una pieza inconsistente e inservible. 

He probado a reducir la presión que el feeder ejerce sobre el filamento, pero el resultado es el mismo. 

También he observado que a medida que el filamento se aproxima al extrusor, el grosor de este tiende a aumentar, por lo que en un inicio había supuesto que era un problema de obstrucción del extrusor, pero cambie este por uno nuevo y el problema persistía.

¿Podéis darme algún consejo, o sabéis como solucionar este problema?

Gracias de antemano

    Buenos dias . Que material utilizas ?

    Todas las piezas que he impreso han sido en PLA, al principio pensaba que podría ser un problema debido a que el PLA absorbe humedad, pero también ocurre el mismo problema con rollos de filamento nuevos.

      • Here it is. The new UltiMaker S7
        The UltiMaker S7 is built on the success of the UltiMaker S5 and its design decisions were heavily based on feedback from customers.
        So what’s new?
        The obvious change is the S7’s height. It now includes an integrated Air Manager. This filters the exhaust air of every print and also improves build temperature stability. To further enclose the build chamber the S7 only has one magnetically latched door.
        The build stack has also been completely redesigned. A PEI-coated flexible steel build plate makes a big difference to productivity. Not only do you not need tools to pop a printed part off. But we also don’t recommend using or adhesion structures for UltiMaker materials (except PC, because...it’s PC). Along with that, 4 pins and 25 magnets make it easy to replace the flex plate perfectly – even with one hand.
        The re-engineered print head has an inductive sensor which reduces noise when probing the build plate. This effectively makes it much harder to not achieve a perfect first layer, improving overall print success. We also reversed the front fan direction (fewer plastic hairs, less maintenance), made the print core door magnets stronger, and add a sensor that helps avoid flooding.

        The UltiMaker S7 also includes quality of life improvements:
        Reliable bed tilt compensation (no more thumbscrews) 2.4 and 5 GHz Wi-Fi A 1080p camera (mounted higher for a better view) Compatibility with 280+ Marketplace materials Compatibility with S5 project files (no reslicing needed) And a whole lot more  
        Curious to see the S7 in action?
        We’re hosting a free tech demo on February 7.
        It will be live and you can ask any questions to our CTO, Miguel Calvo.

      • UltiMaker Cura 5.3.0-Alpha 🎄 Tree Support Spotlight 🎄
        Are you a fan of tree support, but dislike the removal process and the amount of filament it uses? Then we would like to invite you to try this special release of UltiMaker Cura. Brought to you by our special community contributor @thomasrahm
        We generated a special version of Cura 5.2 called 5.3.0 Alpha + Xmas. The only changes we introduced compared to UltiMaker Cura 5.2.1 are those which are needed for the new supports. So keep in mind, this is not a sneak peek for Cura 5.3 (there are some really cool new features coming up) but a spotlight release highlighting this new version of tree supports.
