Is it possible that coloured PLA filament require more heat than black filament?
I can print no problem using black filament at 200C, I switch to blue and first layer has problem sticking. Save file, same setting, same everything except filament color… Even the same filament source…
Yes, the different colors have different thermal properties.
No, the different colors don’t inherently have different thermal properties.
But filament can vary from spool to spool due to different polymer blends and additives - you might get one kind of black one week and one with totally different properties the next week. Unless you’re buying from a super-premium source, like @Faberdashery_Ltd1
I usually print at 190-200C, but when I print white I need to go over 240C
Argh, the RepRap wiki. Always good for some outdated surprises.
I’ve seen that info on the wiki back in 2010 - it’s a prime example of many of the seemingly set-in-stone rules that circulate in 3D printing forums that never seems to get questioned.
That set of rules might have been true for that one specific batch from that one specific manufacturer, but it’s in no way universally applicable.
Yes and some print better than other colors. I find black kind of hard to print with.
@Andre_Courchesne1 Even if it isn’t the colors affecting it directly, yes you may need different temp settings for each roll of filament, depending on quality, age and supplier.
Just tried at 210C and same result. I’ll try bellow 200C a bit later.
@Andre_Courchesne1 have you tried drying the filament before use?
@Thomas_Sanladerer Strangely I never had to do that with my black or solver spools.
It’s printing right now at 230C and it’s better not perfect, but the 1st layer (especially the infill areas) stuck to the tape which is good.
Printing done at 230C is not that bad, but could be better. I’ll try at 240C later.
240C make a mess, worst than at 200C…
Jumping 10 degrees is actually pretty huge, I recommend only moving up and down 1.5 deg C during testing and doing small test prints.
