How to clear plastic globbed in hot end?

Recommended Posts

I walked away from a print with ColorFabb XT, checking on it after a couple hours I found part of it had lifted off the bed and the nozzle was printing in air. This resulted in a lot of plastic ending up sticking to the nozzle and flowing up into the hot end. There is a large glob of solid plastic up in the hot end/nozzle and not sure the best way to salvage. Can I safely apply heat with a hot air gun to soften it?  I am getting a heater error when trying to heat the nozzle now. Thanks for any tips/advice!

I'm in U.S. I think my printer is in the first batch shipping from the U.S. distributor last year.

The hot air gun did the trick - came off just like peeling a pile of old gum off something. I got almost everything, but there's still a little residue left in a few places. Printing great afterwards, but I think I shortened the PTFE coupler life (unfortunate since I just replaced it).

As great as it is getting quality time with my hot end, this is not something I'd like to repeat :) Do you know the name of the tiny white ring, or where I could order it?

Thanks!

You have to buy an entire hot end kit from fbrc8.com. I've never had this problem in years of printing. The filament goes mostly down - not up. For me. Not sure why yours curled up so hard.

you could just use some kapton tape. aka polyiminide tape. And wrap it around the nozzle. That stuff can handle the hot end even at 300C.

If you buy the white ring though it is incompatible with the Olsson block (google it if interested) and the Olsson block lets you change nozzles so you can print with larger or smaller diameters.

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
