I need to create parts for our company's machines. I prototyped parts with SpoolWorks PLA and for final items I decide to use SpoolWorks Edge as it should provide better long term quality. Problem I'm facing now is that printed parts looks ok but it has extremely poor layer adhesion (and it's brittle). (I can brake of chunks by hand which was not possible with PLA). I tried printing with temps ranging from 225 to 265°C and bed temps around 70-80 °C. With temps 225 - 250 I get nice looking finish and above that prints starts to have weird - bubbles like finish. My printer is capable of printing PLA, ABS and NinjaFlex without problem, so I don't thing that it is problem with HW. (I'm, using Prusa i3 with E3D v6 hotend). Does anyone have similar experience or some suggestion what might be wrong? PS: Now when I'm reading message again symptoms that I'm describing looks like wet filament: http://e3d-online.com/Edge says: However prints from wet Edge will be notably more brittle, with reduced fracture toughness and tensile strength. However I have this material for one day so it's definitely not wet from my place where I store filaments in box with silica gel.
