Has anyone on here tried it?

I haven't - the price plus shipping from DE outweighs my curiousity. I asked the Ultimachine guys at MF:NYC about it and was told they hoped to have it in a few months, maybe.

 

There are apparently lots of different variations that are possible.. Somebody (not Ultimachine) was telling me that people are extruding leather, too. Hard to picture..

Wow leather, i expected to hear hemp after reading about the suspected binding polymer. i can imagine what that might smell like while it’s extruding, i'm picturing a bunch of hippies around a reprap .

If 1.75mm of the wood filament pops up ill have to try it out.

I have tried it a little bit. Haven't had time to finish the .5kg I bought but what I can tell you based on my findings is that I had to run a larger nozzle than I normally do. It seems to clog smaller nozzles like .35 and .4 so I switched to a .5 for it. Other things that I needed to do is keep my feed rate high because I found that it if was too low it can even plug a .5. Temps are fineky and if too high the filament will cook before it is extruded causing another way to clog it. Un-clogging it was easy just annoying. I would just bring my hotend up and use a .35 drill bit to poke out the nozzle. Usually there was enough pressure left in there to get it going again. In short I found that there seems to be a very narrow window between success and failure with it. Hope my preliminary findings can be useful to someone. I'm also working with various other materials both for need and hobby. ABS,PLA, (obviously) but also nylon, HIPS, HDPE, and Santoprene on two of my custom designed large format Prusa derivatives.

By the way I am not in Boston. I hope I am welcomed.  I am actually around San Francisco but one thing that I have found is that there is no one source to find out things with 3D printing. It pays to be plugged in to as many places I can find. I never know where the next piece of information I need is going to come from.
