Faberdashery Black

[thehitman04 0]

Hi, i recently got some of this for some badges im printing but i cant get it to work, it kind of just globs up the extruder and i have to heat up, insert filament then cool and remove which is working fine to un block it but then upon re installing it does it again. The nozzle is totally clear as ive had a 0.3 thread wire inside and theres no resistance but not sure what to try at the moment.

Any ideaS?

On what machine are you printing?

What temperature are you using?

Is there any reason to believe the problem lies in your feeder or in your printhead?

If you swap it with any other filament you have lying around, does it make a difference?

-Does that work?

Sorry i was in a rush to leave when i posted, its an ultimaker 2, i tried at whatever the standard is, 220? And at 230 i think. Im not entirely sure where the problem lies to be fair, but it was printing in the ultimaker blue not long before i swapped it, which was printing fine. I can put the blue back and run it if you think it may help?

220°C should be fine.

Did you buy the filament from faberdashery directly?

If you re-insert your blue filament and it prints like it's supposed to, then it's most likely a problem with the filament.

Does it smell differently than the UM filament?

I had a recent delivery of Faberdashery black ( 2 weeks ago ) and have been printing fine at temperatures ranging from 195 - 220. You have measured your nozzle, measure the filament too just to rule that out... maybe its a little thick?

Ill try now and re install the blue, do you mean does it smell different when its heated up ?

I havent measured the nozzle but the filament is 2.84mm which is what its meant to be i think. Id have to get some more wires from work to measure the bore but i think its around the .4 mark as im using 0.34 wires and the clearance around isnt a lot

quick look is it came through fine but as my bed level is out slightly didnt print properly, but material flows no problem

Just to be 100% sure - black is PLA, not ABS?

I would switch back to the working UM Blue, to check the feeding system.

Yes its pla, thats what i ordered anyway. Is there a way to tell by looking at them?

I printed a few things in blue last night and they came out great

I have to admit, the black does seem a little thicker when it extrudes... i tried some again today and it behaves differently to the UM blue for sure.

No doubt it does behave differently, because PLA, like any other plastic, is never exactly the same as some other manufacturer's PLA. There might also be slight differences between different colors of the same manufacturer.

In the worst case, there may even be differences between different production batches of the very same product...

If it's faberdashery, then it's PLA. They don't make ABS.

PLA smells somewhat like pop corn or maple syrup when it's extruding. ABS smells like petroleum (inhaling these fumes is not very healthy, by the way).

That's what I meant by "does it smell differently":

If you compare the UM blue to the faberdashery black, is there a significant difference in how they smell when extruding?

I'm asking that because I have a very good black filament from ProtoParadigm. But this one smells like ABS some times (I have never printed ABS with the printhead I'm currently using before so there is no remaining ABS from earlier prints...), so I guess this "PLA" may actually be a more complex formula than other PLA brands.

If your Faberdashery PLA smells differently than the UM blue (I mean really different, not just a slight nuance because it will definitely be different by a slight nuance), then it's not really faberdashery black...

...which brings me back to a question I already asked before:

Did you buy the faberdashery black from Faberdashery, or from a reseller?

It smells the same to be honest, and yes i bought it from faberdashery direct. Its sorted now anyway, i did a few more in blue then back to black and it worked this time round. Who knows ? may have been something clogged or something
