A few days ago I received a roll of filament that I had won by entering some settings on Filaments.directory.
It is a spool of red Extrudr GreenTec. http://extrudr.eu/collections/bdp/products/extrudr-green-tec-red#.
It is supposed to be some biodegradable ABS replacement.
Printing with this stuff is …a challenge.
Small parts tend to stick to my heated bed better than super-glue, and larger parts warp like crazy.
I tried printing a part of approximately 12 cm, and it came off the build plate after an hour of printing.
It is a shame this happens, because the small parts that do succeed are rather nice. I’m currently printing some cable chain elements, and even those warp. Not enough to throw them in the bin, but enough to notice.
So I was wondering if any of you have experience with this kind of filament?
And then, suddenly I realised, that printing anything that resembles ABS, needs a heated bed temperature of at least a 100 degrees Celsius to prevent warping. The box it came in said 0-60 degrees, and 170-230 for the hotend.
Anything lower than 220 however, results in very weak parts. So I’m trying 100 degrees now for the bed, see how that goes.
@Alex_Skoruppa , funny that, at the moment I would never have expected this to be someone’s favourite.
I’m printing on glass, with hairspray.
And 50 degrees won’t work, it warps like crazy. I am using 100 degrees now, and that seems to work. Anything below 220 creates insufficiently bonded layers. I printed a tree-frog at 200, and it broke in two trying to remove it from the bed.
It works now, but it is way too expensive for normal use. I can get better results with locally supplied ABS at half the price.
