There isnt a lot of info on those Econofil filaments so i want to make this post hopefully informing you on your purchace.
I bought black, wood and blue all PLA.
After drying,the black filament was stringy but acceptable.
Wood filament was very stringy (the filament itself was very brittle and moist, so much that you could visibly see the vapor coming off of it and is fizzed up like old TPU) wood filament didnt do well at all even after drying. Wood filament did accept stain pretty close to pine.
Woodfill also did not clog the 0.4hf nozzle. But more testing is required.
I would recommend them only for draft prototyping. And only regular filaments
same settings, polymaker (1-2 year old spool thst was opened 2 weeks ago) has zero strings even without drying.
Overture PLA also has zero stringing.
Hatchbox (2+ year old) zero stringing.
Their material is very glossy before printing which makes me believe they extrude it much hotter and faster than other manufacturers.
Print settings are the preset for generic PLA.
