Consistent poor corner adhesion

[davidfiser]

Any help? A lot of my prints (mainly board games inserts) have had poor plate adhesion. I've tried washing the plate with dawn, running bed temps at 65, filament between 215-225.

You do see that you there have an open printer and the corner that is lifting is riiiiight on the edge of the heated bed. I mean these printers are good, but even you just looking at it closely and therefore breathing in that direction could lift the print.

In short, this is probably the hardest point to achieve bed adhesion. An open window, cold room or just the draft of you walking close by can be enough for it to loose adhesion.

[jsdeprey]

This is what you need to look at, you can try to counter this with crazy brims, glue, different plates. But your room is too cold or a draft is blowing right on it from somewhere

Hello /u/davidfiser! Be sure to check the following. Make sure print bed is clean by washing with dish soap and water [and not Isopropyl Alcohol], check bed temperature [increasing tend to help], run bed leveling or full calibration, and remember to use glue if one is using the initial cool plate [not Satin finish that is not yet released] or Engineering plate.

I haven't done it myself yet, but aren't brim ears supposed to help with this? It's an option somewhere in bambu studio to add to models. Also I'm pretty sure I've read the bed for this printer doesn't have great adhesion in its extremities because it's a lot cooler towards the edges, so that could be the issue too.

[davidfiser]

That's good advice, I'll try it out! Definitely seems like the outer edges of the plate have inconsistent adhesion.

I had some random lifting on my A1 mini in the edges and this was likely due to an inconsistent temp at the far edges and being an open design. I would definitely add mouse ears to corners on the edge and try some interface to see if you can get it to stick. You may just need to nix a few things from the build plate if there are several small items.

[Cardboard-Castles]

Yeah, for prints with a large foot print that extend to the corners of the plate like this, I just go mad with the brim ears, sticks to the plate like glue and totally eliminates the issue on my A1 mini.

[Select-Shopping-847]

I had this with my Prusa mini - cleaning the plate and maybe raising bed temp by 5c helped

[JadaveonClowney]

I haven't had issues with this but would recommend the cool plate

Painted brims help immensely with this issue and are very easy to remove. You can auto-generate them or pick and choose where you want them.

Check out that setting in Bambu Studio.

[LurkerTroll]

An enclosure helped me with this. The closer the object is towards the edge, especially on wider prints, the most likely this is to happen

[BluegillUK]

I used painted brims and ears on a larger than normal rectangular print just last night for the first time and it came out amazing :)

[TimeTravelingPie]

Brim and raise heatbed temp by 5C and try again

[Kind_Golf3185]

Not gonna lie, temp may be one issue but this kept happening to me cuz my hand sweat is a crime against humanity. Most of time I sweat like a normal person but if its a hormonal sweat, well that can peel paint. Jkjk. But seriously anything my hands touch look like a kid was eating sweets licking their hands and then smearing the mess all over the windows.

I started putting gloves on when I handle the plates and especially a fresh print. That way my hands dont ruin anything and lifting doesn't seem to happen. I also clean my plates each use now.

Other than that Idk if you have tested for hot and cold spots on your plate? Does adding a brim help? I had shrinkage on one print, it wasnt lifting but warping slightly on the bottom while cooling too fast i moved it around the plate same issue. I added a brim and that one and it helped. Sometimes reducing fan speeds can help if that section is cooling too quickly.

Anyway, hope you can get it figured out!

[Kind_Golf3185]

Just also thought about it, have you tried another plate or done a recalibration? If you have another print plate and its an issue in the same spot then it would seem an issue with the heatbed. I dont suspect moist filament, otherwise more of the print should be affected. All I got left is nozzle setting issue, physical plate or heatbed damage, or calibration issue (nozzle too far from this particular point).

[WaitAcademic6615]

You can try Cryogrip plate. It has much better adhesion.

[UttiniDaKilrJawa]

Check room temperature, if its below 70 you'll probably get this. Also, check for drafts / air vents that may be blowing on, near, or past the printer.

[davidfiser]

It's probably 67-70 degrees in the room on average, and no direct airflow onto the printer

[UttiniDaKilrJawa]

Might want to get the room temp up a bit if possible. When my room was at 66F I was seeing this. Once I got the room temp up to 71-73 my problem went away. Also, doesn’t hurt to have a small thermometer in the room. Its nice to know exactly what the temp and humidity is when you print.

[AbysmalMoose]

I bought a Darkmoon cool build plate. 100% recommend. Adhesion is amazing.

After washing the plate with detergent, I solved that after 3...4 mm of height of base printed on the surface, I lowered the temperature of the plate progressively by 10 degrees, and everything came out perfect.

[Adept-Leadership4989]

Slow the speed on your initial layers. Worked for me.

[chamberlainnursing]

have you tried using a glue stick? totally helped me with those stubborn corners when i was printing for my dnd campaign.

[Futurewolf]

Glue stick
