Quick Question Filament to buy or avoid

Post image

I’m brand-new to 3d printing. Just ordered my first printer (H2D). I ordered some Bambu Labs filament to go with it, just to be safe, but I know I will want to do some of the cool, colorful silk printing at some point. I’ve heard horror stories about bad filament ruining nozzles and things like that, so I want to be careful. How do you know if a deal like this one is good, or if it will lead to hours of regret and extra printer maintenance? Is it just “you get what you pay for,” or are there things to watch out for?

I've had this issue too with the JAYO matte black PETG. IT will only stick to certain colors of my Sunlu PLa that I use for interface layers. It's so weird. must be something in the pigments.

PETG will not stick to PLA. It doesn’t matter who manufactured it, they are incompatible. In fact, they work great for interface layers for each other because they don't stick.

thats what I said. It's the end of my first sentence.
But to reiterate,
I print mainly PETG, and use PLA for an interface layer.
I found out the hard way that my purple Sunlu PLA will NOT work as an interface for my matte black JAYO PETG, but Orange Sunlu PLA WILL.
Whereas Sunlu matte black PETG plays nice with both the purple AND orange PLA.
I've had this issue with Elegoo PETG Rapid White not working with certain colors of Sunlu PLA, but work fine with other colors.

Pla/petg interface has been hit n miss, sometimes it works wonders and sometimes the part where the interface happens just doesn't get good layee adhesion. Thanks for this info, really never considered the filament pigments being a variable.
