Rulon Failed

The Rulon-lined hot-end printed ABS, for about 2 hours, then jammed up.  So, initial testing of Rulon was not positive.

  1. :( what a shame.

    Did it stick to it? or get soft and expand?

    Have you ever tried a section of glass tube as a liner?

  2. Hello,

    I am not sure what happened, exactly, as I sent this away for testing. Once it is shipped back, I intend to mill out cross-sections and see what it looks like internally.

    I haven't considered a glass tube as I don't have the experience nor tools to work glass. If glass liners would work, making them on a production scale would be another issue as well.

    Regards,

  3. Hi Brian,

    You can get Borosilicate glass tubes with a 6mm outer 3mm inner and a very high tolerance for the scientific community, you can get them cut to order, but it's easy to score and snap them to size yourself.

    I will try one at some point, but if anyone else wants to give it a go - here is a place in the UK that sells tubes - http://www.glass-solutions.co.uk/glass-tubing-calculator.html

  4. Hello,

    Sorry about the late reply. I was considering your comment. The only thing I am wondering about would be how to seal them between the glass and the brass.

    Regards,

    Brian

  5. Did you try PEEK-PFTE combination material as TECAPEEK http://www.plasticsintl.com/tecapeek.htm
    probably no more PTFE tubing will be needed
