Filament vendor: Colorfabb
Hotend used: V4
Nozzle: 0.5mm Stainless
Printing temperature: 260C
Other information:
-Bed: PEI-surfaced MIC6, 60C
-Slicer: Simplify3D
-Retraction: 1.2mm
-Cooling: 97% starting on layer 2
-Default printing speed: 2300mm/min
-Outline underspeed: 50%

-Extruder tension: I had to increase the tension quite a bit to get through the first print without the drive gear slipping and the filament stopping mid-print. It seems fine now.
Observations:
This is carbon-filled PETG/Amphora. It makes visually appealing parts that print easily with (almost) my normal PETG settings. I used the .5mm stainless nozzle for lack of a hardened steel alternative on the M2.
What's striking is the matte texture right out of the printer and the pure black color. The surface texture masks layer boundaries and toolpath traces on top surfaces for an appealingly uniform, professional appearance. Mechanically, it seems to be quite stiff; a bit more than PLA perhaps and maybe about the same as ePC, but not as stiff as PC-Plus. It seems to print as easily as PETG.
With the excellent deep matte black, high stiffness and PETG-like glass transition temperature, I'm most looking forward to using this for optomechanical parts. It may also be the best material I have so far for printing large parts (larger than possible with PC's curling/shrinking problem) that are also very stiff and won't deform in a hot car.
