the tempareture on the spool is usually given as quite a large spread.
usually 200 -240 for pla.
I have never bought a spool of pla that goes as low as 180-190.
So why people try and print pla at these temperatures, I have no idea.

225 is high, I usually use somewhere between 200-220.

And yes the colour and brand of pla make a lot of difference.

I find that black pla prints well at the lowest temp. White and coloured pla tend to print at higher temps.

It also depends on how your printer works. Direct drive will get away with lower temps than bowden systems.
Also the quality of your heater and the ability of the thermistor and board to keep the temp stable will make a difference.

There is currently NO standardisation for 3d printer filaments.
Different producers use different additives and don't have any legal requirement to declare them.

I'm not colour focussed, so I tedn to use whatever make and colour filament gives me best results - spray paint is cheaper than filament if people want to change the colour.

Hands down the best filament I've ever used if flashforge's red.
It's a semi-translucent filament, but just fabulous to work with and seriously tough.

Printed a little plastic key for paper towel holders recently. just a flat piece of plastic with a cutout. 1.5mm thick.
The flashforge red priunted it out bang on specification.
As the original was white I switched to esun white filament.
Kept all the settinsg the same and used the same stl.
The white ones are between 0.1 and 0.3 mm thicker than the red one.
I have no idea why.

3d printing is currently as much an art as a science. Until we get some kind of legislation to standardise filament manaufactur, that's how it's going to stay.
