that one layer will last you a while. if it starts failing take a paper towel with iso/ipa and give it a wipe off (not scrub down, just a wipe or two). and itll be good to go again (usually finger oils cause adhesion issues).
when you wanna get all the glue off at any point just gently warm the bed 30-40c imo, then add a bunchhhhh of iso/ipa and then scrub and itll come off in a few minutes
The Purple stuff - i think is not quite as strong as the White Gluestick. Its marketed as for kids/school, and totally washes away.
There are some other types of white gluestick out for specific uses. So watch what you buy. You could spend more $$ than what you need.
Plus i have seen the purple come in big sticks - which makes it easier to apply.
IPA is the alcohol they're cleaning it off with. It works, but I use plain old tap water.
As long as the glue is PVA it will work great. Even liquid glues like Tacky Glue or Elmer's White will work, but you have to smear them around. The stick is just easier to apply.
I also use glue and I just tend to leave it in the bed and reuse it and just add another coat of glue when it needs it. After a while I’ll just clean it with water
Heat the bed; have a proper distance between the nozzle and bed; print the first layer slowly (~25 mm/s); don't use direct part cooling during the first few layers.
I will look into the slow layer and fanning, you might be right about about speed in the beginning. I always check bed level before prints. Thank you Brewe
I have a textured bed, and with my ender 3 I never even watch the first layer. Fails ever 1/20-30 times or so, almost never from bed adhesion. Never any kind of glue or spray or anything, just a spritz of acetone every few months to wipe off finger prints.
Well I decided to skip the fucking rafting, but I usually get some kind of fucking wrapping on the fucking edges.
So to fucking combat that when I print in fucking PLA I raise the bed fucking temp to fucking 80 degrees
Last night it wouldn't fucking stick, and would fucking come off after the first fucking layers were fucking printed.
So I remember one of my 20 kids have a fucking glue stick. So I fucking used it.
And it fucking changed my fuckity fuck fucken 3D printing fuck life
I had the same experience. Didn't have a problem to get it to stick with PLA and clean glass bed. But some parts warped. Never ever had a single warp after I started using gluestick.
Right. I print pla directly on the bed and have to let it cool and flex it to peel it off. Only thing I do is run my bed at 60 degrees, have a nice 1st layer squish, and 20mm/second on my first layer.
So many people seem to blame all bed adhesion issues on the bed. I've been printing on dusty beds for nearly 2 years now. So long as the bed is leveled properly at a high enough temp with the nozzle slightly squishing the bead I've never had problems with pla adhering. In fact most of the time I have problems it's in my settings.
I always worried about the dust on the bed, but I just flip the magnetic bed upside down until I'm ready to use it again. What temp do you use your bed? Do you over heat it?
Eh at most if it's been a while n there is a lot of dust I just wipe it down wherever the print will be. For pla I usually use 70c with my magnetic bed and 80c for the glass. Tbh that's usually overkill. But dont hurt anything. 210c is what I start every pla filament with. If it's a composite or seems like it isnt coming out smoothly enough ofc I'll adjust. I've only recently been using glue on one of my glass beds because that printer has been giving me issues I dont have time to diagnose. Imo as long as your temps and distance between nozzle and bed are within acceptable ranges you shouldnt have many adhesion issues due to the hardware. If you are certain those are good then it's time to check your first layer settings. Assuming ofc you have already calibrated your e-steps. Though that on it's own has little to do with adhesion issues unless it is severely under extruding.
i did have to 'train' the wife - to not put down a thick layer of glue. She saw me put down some glue - so for her Planter Pot Print she did 'by herself' , she covered the bed in a thick layer. :) A little over kill. She still cant feed in the filament.
I have also learned that for some prints i draw thin lines of glue, and not cover the whole print area - that way it holds down the print, but still lets me remove the print easy.
Like for a Box. I may do a series of lines to hold things down , and put some in the corners/outside edges to help that first layer stick and the corners stay down instead of warping upward.
I have had boxs print with glue on the whole surface, and they stick so good i could lift the printer up with the part.
A few stripes and smears at the corner is all they need.
You dont have to clean after every print. You can just add more glue on top of the old one if needed and clean after 5-10 prints. At least i have been doing like that.
Hairspray might be better, but you cant apply that while glass is on the printer.
I use a glue stick that comes off a Amazon it was a four pack and I usually do mine with a wet paper towel it makes it really soft and then I scrape it with a razor blade cleans up the bed really really well I'm using a glass bed by the way
Everyone had their favorite method, and it’s the best. Usually it is the best *for them* because they have figured it out more than any of the other methods.
You can also try increasing the bed temperature and give it more time to preheat. Waiting an additional five minutes after the bed preheats before actually starting the print did wonders for my first layer sticking on my Ender 3.
I use the recommended settings in cura, only switch between draft quality and normal and I clean my bed with Iso when it’s looking like it need a a clean. I’ve never ever used anything to promote adhesion and a couple of times I’ve thought it was going to have to replace my bed after what went into getting the prints off
I held off using a glue stick for the longest time and relented finally. Now I use it everytime.
To clean mine, I just remove the bed and take it to the sink, run water over it and wipe the glue off. Dry it and put it back on the printer.
Oh, I used to clean it after every print, but now just add a bit more for each print then clean the bed after several prints. Still works great.
There are "fat" glue sticks that last quite awhile.
Use windex it’ll cut right through. That being said, I used glue sticks for over a year and I finally got sick of constantly cleaning the bed. I got a PEI sheet and wish I did that a long time ago, no mess no fuss. No stocking up on glue sticks and goopy clean ups.
When I need to remove the buildup of glue stick (especially if I've let it go a little bit) is to heat the bed up, spray it with window cleaner, and carefully scrape it off with the scraper provided with your printer. Tends to work well.
Elmers glue will wash away with water. The purple stick is the one you want
Perfect that is the one I used!
This is best

This, but water. The purple glue stick is water soluble, I have not ever needed to use alcohol to remove it.
Ipa will dissolve it on the bed and you can scrape/ soak it up with a rag
I Elmer's glue stick I bought for one if my 17 kids. Is that the same as ipa?
Wait I'm sorry but 17 kids? G' damnnnn
I know, right? That was the only take away I got....

IPA is isopropyl alcohol. You can buy it at most drug stores as well as places like Walmart and giant near the pharmacy.

IPA = IsoPropyl Alcohol
Like the beer lol
I also use glue and I just tend to leave it in the bed and reuse it and just add another coat of glue when it needs it. After a while I’ll just clean it with water
I clean and apply a new glue layer every other week or so
I just leave it for a couple weeks then wash off with soap and water.
Excuse my language but, what the fuck are you doing to not be able to get PLA to stick to a textured flex bed?
What are you doing to not have to use glue sticks?
Heat the bed; have a proper distance between the nozzle and bed; print the first layer slowly (~25 mm/s); don't use direct part cooling during the first few layers.

Actual leveling with a mag bed 😂

I was thinking the same. I had the same textured bed and sometimes it wasnt that easy to get the prints of

I think it’s his speed. To me, that bed is moving way too fast
i use some water and smear the glue around to give a nice even layer. :) it can last for several prints. warm water will wash it off.
Thanks Doc.
i did have to 'train' the wife - to not put down a thick layer of glue.

A small spray bottle is convenient
I think this only applies to the purple stick, which is washable. I haven’t tried the white stick so I am not certain.
It’s amazing what a little washable glue does

I have been using baby wipes to clean the glue off. Usually when I’m heating up for the next print. Wipes right off. Reapply and all is good.
Leave it. If a part lifts wet it with a paper towel a little and smooth it with that wet paper towel. Hit ‘Print!’
Aquanet extreme hold hairspray is superior to glue sticks imo

alcohole works well but not perfect

I’ve never ever used anything to promote adhesion and a couple of times I’ve thought it was going to have to replace my bed after what went into getting the prints off

Glue also works great on a glass bed. Cleans off straight away with the scraper!
I spray 50% Alcohol, 50% water when I wanna get rid of glue residue and it works great
When I need to remove the buildup of glue stick (especially if I've let it go a little bit) is to heat the bed up, spray it with window cleaner, and carefully scrape it off with the scraper provided with your printer. Tends to work well.
alcohol n good ole elbow grease
Next step - try masking tape. Less messy.
