New GreenTec Filament from Extrudr

GreenTec 02 GreenTec 01 Greentec 03





On the left printed @0.15mm Layer height with an 0.5mm nozzle on my DuoCore @210°C. On the right printed @0.2mm Layer height with an unknown nozzle @200°C on a friends i3. What is interesting are the differences in slicing, the left was sliced using S3D, the right one with Slic3r.

I was very positively surprised by the new GreenTec filament from Extrudr, that i ordered on a whim alongside a couple of kilos of my usual ABS.

Not only does it produce a nice matte finish, it prints without any hint of warp, the stability is excellent and it is a dream to postprocess with any kind of tool.

The only two drawbacks i found so far are that it sticks so strongly to the printplate (aluminum with 3Dlac @60°C) that damage to the part or printplate are a very real threat and the current price of €56 / Kg

I hope the price goes down over time, but even at the premium it might be worth it, especially considered that i don’t have to feel so bad about producing garbage prints since GreenTec decomposes neatly, different to PLA.

  1. Looks like you found the current bugs in Slic3r. I’m back to 1.1.7 and sometimes 1.2.6. 1.2.9 often used on thin wall huge amount of filament.

  2. S3D has also some bugs. Sporadically missing layers (this is the worst one), wrong calculations of wipe, the two I found out.

    On work I made a parser for Slic3r to use it on a Makerbot 5th, the results with 1.2.6 and 1.1.7 are much better than with S3D and of course MakerbotDesktop.

    I’m testing a bit the next 1.3.0 beta, but this is currently not ready.

    The best thing of S3D is it’s speed. But care with missing layers. You can’t see any!

      Thankfully i did not run into any serious S3D bugs, just a few workflow hickups.
