It seems my post was removed for some reason, maybe because I had a filament supplier link in it although I was not advertising anything. It was a genuine question, but it would be nice to get a basic notification when posts get removed or not approved for whatever reason.
So here I try again, no links involved this time:

I just bought a white PLA spool from a trusty German manufacturer (+Thomas Sanladerer had it reviewed once) and it drives me nuts. It just won’t stick to the print bed, no matter what I do. Hot-end up to 220°, bed 70° glass with glue stick or hairspray. It’s like trying to print on a non stick Teflon pan. It only likes to stick to the Hot-end nozzle. I never had issues with adhesion, no matter if it was pla or abs. Bed is level within 0.02mm.
Is there any secret to the white PLA? It’s the first time I try it out.

I’ve always printed PLA onto acrylic or blue tape. Never had much luck with it on plain glass.

Also, apologies about the removed post – it shouldn’t have been. Thanks for reposting.

I print onto glass with hairspray 70 for the bed is too hot 45 -50 depending on ambient temperatures. On clean unused glass I spray one layer and let it dry then a 2nd layer right before printing. If the glass is dirty I use hairspray and a scraper to clean it off. Spraying hairspray on old hairspray turns it to liquid again. Easy to clean. If it has anything else on clean with anything from acetone to xylene. Wash the glass after and reapply hairspray again.

I print the cheapest, no-name PLA on plain, cold, window glass coated with Aquanet Super Hold (purple can) hairspray and it sticks like crazy.

Guys, let’s talk about your experience with WHITE PLA, as I said, I never had issues printing PLA and ABS so far. Always had perfect adhesion, so things like under/over extrusion, distance to bed, etc. are in my opinion things that I already taken care of.
I would try going even higher with the temp, maybe 230-235 ? I read somewhere that the white would need such temps…
The PLA is from dasfilament.

Tried again at 230C, fresh coat of Hairspray. A little better, but corners are just being dragged and adhesion is really poor…
I guess I have to take out the velcro and print on a raft… I have no other ideas

@David_Sherwood Yes, you are right, it was squishy because as a last resort I tried to reduce the first layer height with 0.05mm, and it did improve to some degree. So instead of printing at 0.2 mm I was printing at 0.15 with the same extrusion as for 0.2.
Now I did manage to get a semi-decent first layer going up to 235°C and 75° heatbed with a squished layer. Anything below that and it would just drag it all over. Second layer went perfect at 210° and 55°.

Lower layer heights for the first layers will make adhesion worse, as that leaves less room for soaking up imperfections in the bed. My slicer profiles are generally set up to increase layer height and width by 30 to 50% for the first layers.
Keep in mind there is a difference between layer height and nozzle height - lowering layer height will also decrease the amount of material the extruder will pump out, simply lowering the nozzle and setting Z0 closer to (or even below) the bed will smear the plastic stronger against the bed surface.
I’ve been printing DAS PLA at 210/55C onto PEI, glue stick, MagiGoo, anything, essentially, and got good adhesion every time. Color shouldn’t affect this, but some colorants may absorb more moisture than others.

I have started from my standard settings from the last spool of PLA I had. Just changed spool and adjusted the diameter in slicer. While I never had adhesion issues before, I had absolutely no luck with this white one. My bed is extremely flat and level, so this is no issue. @Thomas_Sanladerer ,do you happen to have the DAS White PLA in your “stock”, just to check if it’s really behaving so totally different…

@Romeo_Pavel while i do have a few different colors of DAS (natural. opaque, etc), i don’t have the white version specifically. Though i’ve not seen significant differences between different colors of quality filament yet. Have you tried another color from DAS?

11

@Thomas_Sanladerer No,this is my first filament from DAS. I only used cheap e-bay stuff so far with great results.

So I tried with plain glass, as suggested by dasfilament team. And surprise surprise ! There are absolutely no adhesion issues ! For me at least, it’s the first filament where additives like hair spray and glue-stick actually not only does not help, but on the contrary, it makes things worse ! So thank you all for helping me out.
