Warping issues with PLA Galaxy (but not Matte or PETG on same model)

Hi all, I am currently producing my first product from 3D printing and offering a few different colours. I have fine-tuned PLA Matte and PETG to print flawlessly for my model (pictured) without any warping; this is a functional tool so I am using 5 walls and 25% gyroid infill; I have stress tested it but I really don’t want it breaking out there in the world so I’ve perhaps over-built it a bit now, but that’s fine for now.

In general, to fix the warping for my model, I raised the bed temp by 10 degrees from standard and I use brim ears on the trouble corners. The print room is quite cold, which is why I probably struggle with warping, but I got it figured out with these two materials. Another fix was a specific orientation on the bed, weirdly if the tool head faces towards the back of the machine then the print will warp again. I have also used taller skirts on prints to help with the possibility of drafts, but as I am printing a lot of these, I want to cut down on waste.

Anyway, I love PLA Galaxy Purple as my signature colour - but I can’t get it to print this tool without a bit of warping. It’s only really noticeable to me, or other deep 3D printers, but I want to know some other ways to fix it for the same perfect results I have with the others. I have seen people suggest turning off aux fan or 20% at maximum, which I am trying on this next batch. But I just find it a bit strange that PLA matte works perfectly, and even PETG which I have had a lot of troubles with, but PLA galaxy is difficult. And yes, I am cleaning the buildplate regularly…

Thanks in advance!

The most prominent factor in warping is environmental cooling. You’ll have far fewer warping issues if you move your printer to a warmer location or make it cozy for the machine with a dedicated enclosure or tent.

The anti-warping sweet spot for my X1 is 35-39°C chamber temp with PLA. However, this does lead to heat creep when ironing or having many retracts in a short time.

Perhaps the glass particles in this filament make it quicker to cool down. I know long term I should make an enclosure - especially as I’d like to experiment with the more difficult materials as well like ASA, etc… just lack of space at the moment. Thanks for the tip, motivates me to get it done
