Recurrent nozzle clogging

Recommended Posts

Hi everyone,

I need some help here. I recently changed filament for Arianeplast 1.75mm PLA. After a week of very nice prints, my nozzle gets clogged and I can't get any print finished. I clean the nozzle, calibrate the printer, check it with a one-layer print, start a new print and after a few layers the plastic can't come out.

On the 3 pictures my last print, you can see that after a while the plastic won't come out, how the nozzle is beautifully clooged, and the kind of slime I get out of it when cleaning (I heat the nozzle, insert filament manually, cool it and take it out gently while it's slimy around 96°).

The parameters I used are factory parameters, with filament size set at 1.75 (and I got a couple nice prints before everything went frantic).

Thanks for your help,

Amine

Just a little heads-up.

I cleaned (again) the nozzle, with a grey filament to be able to see the black coming out. After almost ten pull-ups, I was able to have a clean grey filament, with no black. I then did a factory reset of the machine, leveled the bed, and reinserted the original black filament.

Here are a few pictures of what is happening at the moment. As you can see, some lines are missing. Seems like the filament struggles getting out of the nozzle, or alternatively, the feeder struggles to push it in, maybe because something blocks outside. I gave it a little help and pushed it manually, and it returned back to normal. The picture where there is no defect is actually taken later. For how long is it gonna print ok, I don't know. I'll keep you updated.

My parameters are default for PLA, with filament size at 1.68, flow at 120% (I noticed the lines didn't touch at the beginning) and temperature at 220 (to give it a little more fluidity).

    • 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.
