I'm not sure why everyone is raving on about this filament, but I guess I'm just in a minority with my difficulties...Tried to print with this using a Centauri Carbon with a 0.4 mm nozzle (I guess that was my mistake, I see a lot of people recommending 0.6 mm, but then why is this not stated in the product description??).

First off I couldn't find a single bit of information on the store page or in the datasheet on what speed is this thing safe to print at, so I had to look up generic wood-fill PLA settings, but this particular material has a really high wood content, 20 %, so those might not really apply...

I had several clogs initially, as I progressively slowed down each test print. I think I had the speed more or less dialed in, and the print was going fine, but unfortunately I accidentally introduced a tangle into the filament while doing a few unloads and reloads, this is of course entirely my fault, but normally it just means that the print does fail but all I need to do is unload the filament, untangle it, reload and carry on printing.....not this time.

I can't stress this enough: This material produces a HUGE amount of tar! It's a black sticky goo that made its way up the heatbrake, through the cooling block all the way to the filament cutter where it spilled out and jammed the cutter too...Yes I didn't notice the filament tangle in time, so the same bit of material was sitting in the hotend for about 10-15 minutes, at 230 degrees. While regular materials also degrade if sitting in the hotend for a while, they don't turn into a sticky, almost unremovable mess inside it.

I had to disassemble my brand new printer's extruder and hotend, completely, including removing the nozzle, and had to use a tool to push a plug of extremely sticky semi-hardened tar out of the hotend. I then reassembled the whole thing, and used some regular PLA to clean/purge the hotend. Initially there still were clogs as the sticky stuff inside couldn't be completely removed , because it clings onto surfaces like glue.

The last high speed benchy finished fine, but it still smells a bit like tar...

While when printing, this material is very nice, be VERY careful with it, use a larger nozzle, AND keep a close eye on the print, because if for whatever reason this stuff stops flowing through the hotend, it'll break down into smoke and tar in there very quickly, and ruin your day...
