New Fillament printing issues

Hi,

If you look at the following link,

[techyman3d.blogspot.co.uk]

The Black print is using new fillament from Fillamentum It has a recommended print temperature of 190 - 220, as I have explained I have been setting this to 190, however it looks like it has been too hot (if you look at the top of the print it has some sagging ) as opposed to the white print which is straight... Have I got this prognosis right? Is it possible that the temperature needs to go lower even though this would be below the minimum of the , or is something else going on here?

Thanks

Do you have a cooling fan? if not try printing 2 or three of them at some distance from eachother to give them time to cool ,it is a verry small part and would require quite a lot of cooling.

No I don't have a cooling fan, i will try printing out two of them though... However the white PLA printed fine

Yes ,might be due to Dye that the company uses ,diferent colors might require diferent temperatures and companys. You can try lowering temperature aswell ofc.

..and a darker filament will absorb more radiated heat from the nozzle

I would recommend using a cooling fan when printing with PLA.
I been printing parts using a luminous green filament from the same manufacturer. At first the print speed was slow 35 mm/s and the external perimeters where curling up, causing failed prints. From some research I found that running the printer faster at 45mm /s and external perimeters speed was auto (0) or 50% in slic3r settings. Hot end was set to temp setting of 195 degrees C this gave better prints. Had the cooling fan set to default settings in slic3r

Excellant interesting , I will check these against the fillament setting I have.. Gives me a good start.
