I was pretty excited to receive my 1.7mm wood sample the other day. It looks really good. very flexible, to the point it is quite difficult to snap, unlike ABS.
I quickly put it in the UP and extruded at 200C. All looked good for a while, as I attempted to print out the cyclonic shape I printed with the Crysta-Line filaments. Anyway, after about 10 minutes the extruder blocked. Damn. Although when cleaning I discovered the tip hadn't blocked but the tube above had! Not sure why, as this is 2mm wide. I later discovered that it is also reccomended to use a nozzle of .5mm. I have a spare which I will drill out ( the stock Up nozzle is .35mm) and try again.
One thing I found was that due to the texture of the wood layers almost disappear.
Here is a picture of what I managed to print out.
