Review on HATCHBOX 3D Printer Filament - 1Kg Spool, 1.75Mm Wood Filament With +/- 0.03Mm Dimensional Accuracy by Don Olsen

I can't fault this filament for anything, really. It prints at a wide range of temperatures and adheres well. Sands and takes stain pretty close to how actual wood does. However, there are a couple of caveats that you need to keep in mind:1. Unlike regular PLA, it is abrasive. It will wear out standard brass nozzles quickly. I'm already using steel plated and tool steel nozzles, so that doesn't scare me off, but you should know about it before buying.2. I have had one nozzle clog with this filament, and it was bad enough that I had to throw away the plated nozzle I'd been using. However, I don't think it was really the filament's fault. It looked like the filament had broken due to stress (I hadn't implemented any stress relief for the filament going into the extruder and was printing something that required a lot of retractions). With nothing to push against to move the filament through the hotend, molten filament just sat in there at printing temperature while the printer kept going. Since there's real wood dust in this filament, that caused it to carbonize and completely block up the nozzle. So keep in mind when printing with this stuff, you probably want to make sure there's not undue stress on the filament that might break it. and you may also want to implement some kind of automatic shut-off if the printer detects that the filament has run out. Better to have a print fail and waste some filament than ruin a $15 nozzle.
