Soon, the trashy yellow/whiteish painter tape will be back to take its revenge
Oh no! I need to hide my old cold glass bed
No need to worry, i still use mine. One of my supports came loose this morning and i superglued it back down. Cant do that with a flex bed.
Hold my beer.
Team hairspray over here
Hairspray gang
Team tape still got your back

How often do you print?
Yeah, hairspray was the one
Yeah, still doing hairspray here, petg with less than 10 adhesion failures on a little over 20k prints
For real, I'll never understand all the people who shout and scream that you shouldn't print petg on glass. I've put probably 5 Kg of the stuff through my various printers, all using bare glass ranging from stuff I stole from my parents picture frames when I was younger, to high end borosilicate OEM options. I've never had adhesion, or over adhesion problems. No Raft. No Brim.
Just hairspray
I killed my glass bed with petg. Learned the hard way. Had nothing to do with the adhesion method (I didn't use anything, just a perfectly clean bed), when the prints cooled the glass cracked off layers stuck to the prints.
99% of my prints are ASA, used PETG once and that was it for that bed.
Now I just use textured sheet springmetal beds
Huh, now I'm thinking possibly the hair spray IS the reason I have never had overadhesion problems. It probably acted as a release agent.
Could be! I've never been a fan of using anything to promote adhesion, technically prints should stick to the bed material just by being the correct temp.
I go to brims before I'll use anything. Sugar water was my favorite go-to though. Sticky under heat, hard when cooled.
That is exactly it, yes. For PLA, hairspray helps it stick. For PETG, hairspray helps it release. Don't print PETG on glass without some sort of release agent. It won't tear up your bed 100% of the time, but it will eventually.
No seems OP just can't figure out he's supposed to print on the PEI surface 🤦🏼
That’s cute. I print many things on the PEI surface and it works great for many things. Did you know it’s possible to have different solutions for different problems?
Kapton is PEI. Years ago, it was just the easiest way to get PEI for hobby printers. I still have a couple 6" wide rolls.
If your bed isn't sticking too well anymore, wash it with dish soap, like some straight up cheap dawn (not the fancy moisturizing). Alcohol is not a degreaser, so once you start to accumulate oil on your bed it starts just spreading it around. A quick scrub in the sink will bring it back to new.
Kapton tape is a brand of Polyimide (PI) tape whereas PEI is Polyetherimide. I'm pretty sure PEI is a "class" of PI though, so I think it's a "all PEI is PI but not all PI is PEI" kind of situation. I know it's a bit nitpicky, but I feel like it's important to make the distinction.

That's not really true but man people like to reshare that, huh.
Dish soap works great for degreasing, for sure. IPA will too, but you will need more than a spritz.
I do wash my beds regularly. I use dawn ultra with a Rubbermaid reveal brush to make sure it’s clean!
Your attitude in this reply, all by itself, makes me assume you have no idea how to print properly on PEI. Nearly anything you need Kapton for, prints perfectly on PEI. What material are you printing? It looks like boring basic PLA.
Take u/kageurufu's advice, some of us might actually know more than you. :)
EDIT: I mean for frick's sake it looks like you're printing PLA with huge brims. Please don't be printing just PLA.
Oh god, I read your other comments, please take u/kageurufu's advice. You're causing yourself so much pain in your hubris.
I don’t know who you are, but you make a lot of assumptions. You claim I have hubris, but your comment is dripping with self-righteous indignation. I have 6 printers with a wide variety of bed types and filaments, but I am always learning. You seem to think that your way and knowledge is the single truth. Good luck to you with that! I am experimenting and learning and enjoying the process, even when snotty jerks like you come along and toss insults around to make yourself feel superior. Have a great night!
A newbie with 6 printers is still a newbie. Good luck, we gave you the correct answer. Go buy some dawn dish soap. 👋
Take care Raymond!
We haven't. OP is stuck in 2019 though.
Yeah I'm sticking with my PEI, lets these newbies find out the hard way we already figured all this out hehe.
There are legitimate uses for tape. But 99% of us will never need them if we have a PEI sheet.
I certainly hope you’re not this vile to all new folks who are still learning. Why would you ever think it’s appropriate to act like this?
It's so strange to me that you're potentially leading a whole generation of ignorant newbies back to the dark ages today with this post, yet you have the nerve to suggest someone else is being vile to them.
There is no valid reason to be using Kapton tape in 2024.
Well you clearly have all the answers then. I’m really happy for you!
Damn, how thin is your skin that you think that comment was "vile"? That was some mild snark at worst.
I don’t have thin skin, I’m just not so simple to think rudeness and incivility is charming or appropriate. But you do you. 🤷🏻♂️
Well, you called a mildly rude comment "vile", so you either have thin skin or you're a liar. Literally no other option there. 🤷🏻♂️
😆😅😅 I am a firm believer in having many tools in the toolbox
thats what she said!
Wait till you get a PEI sheet haha, but yea kapton tape was great before those, until it starts tearing.
I have this on top of a PEI coated glass bed. I have PEI sheets in all of my other printers but this one can be tricky with certain prints.
Spring steel for life--> FLEX = pop!
(no grip and pull required)
They don’t make one for the J1S as far as I can tell!

Damn you! Why’d you have to do that? I’m already at twice my Amazon budget for the month. I’ll order from aliexpress.
Considering it's the exact same brand and board...good call. I'm not exaggerating when I say the PEI spring steel bed was one of the single best upgrades I've made to my printer(s.)
Good luck and good printing.
Yeah I have PEI beds my other 5 printers!
Nice. Even Kapton tape on spring steel would be a pretty solid improvement, I suppose.
If you're having problems with prints that's an issue of layer height or bed heat or first layer fan cooling or all of the other things you can control in a print. Having to put things on the bed of a 3d printer to get a print to stick hasn't been an issue for many years.
I’m so glad to hear you don’t have these issues! How awesome for you!
Oh I can do the sarcastic nice guy thing too.. aww it's so cute you're being so nice to negative feedback in face of being downvoted in every comment you make because you thought you discovered something amazing and despite everyone telling you it's pointless and/or not needed you attempt to belittle them instead of just accepting that maybe your 3D printing knowledge is a little outdated or your system isn't setup properly and needs some tweaking.
I suppose that would seem profound and impressive to simple-minded folk. I’m experimenting and learning, and having fun doing it. I know full well that kapton tape is an old school technique and chose to try it out. I laugh at guys like you who pop along and sprinkle their negativity around because they have no actual skills for meaningful human interaction. Have you ever wondered why you walk through the world the way you do? But carry on!
Oh man! I haven’t seek kapton tape in a printer in a long time. That’s old school cool, man
For sure! I love my J1S and this PEI coated glass bed is great for most things! Sometimes though print is really stubborn and it won’t stick to this bed. Glue didn’t seem to help. Since I started using laptop for this material and print, it’s been aces.
Side note I really wish my iPhone would stop autocorrecting kapton to laptop.
What year is this????
lol!
no is not :( sorry, is not. ... I'd rather go back to abs slurry than to capton tape, it does not bring good memories .. it's expensive, it damages easily, some materials grab too hard some not hard enough... almost everything is better than capton, even regular glass + hairspray is better than kapton :(
To each their own right? I use PEI plates mostly, but for this printer and this specific print —- kapton was king!
of course, but move from kapton was one of the smartest and most important steps in reprap history :D
I still use ABS slurry! Nothing beats it when it comes to printing on large format (1000mmx1000mm) glass beds. Prints stick like nobody's business when the bed is hot and as soon as it cools they pop right off.
try printbite (geralite) :D works even better ... I used abs slurry for a decade and then I stumbled upon printbite :D never looked back
Wow the cost of kapton tape has gone WAY down since Ive used it last, I remember buying this stuff wholesale for the company I was working for at about 50 to100 dollars a roll depending on the size back in the early 2000s from dupont.
Kapton Tape is very closely related to PEI, if not chemically identical. This is why we started coating beds with it.
Kapton is polyimide, but yes, similar to polyetherimide.
I use garolite. Usually when it cools the parts lift off like they are sitting there.
Salt water on glass ftw
Oh shit, now this is a throwback.
Not needing tape in 2024 is magical.
Fuckers will spend money on anything except a PEI bed
I have 6 printers and 6 PEI plates. Who are you talking about?
I have PEI tape which is similar to Kapton tape. Stuff still goes hard after many years of printing.
Just get a G10 plate
Evokes fond memories of my first printer, the Printrbot Simple Metal
I guess glass just doesn't work for some people, it's all I use
Y
This is all ridiculous.
Then just laugh at it. 🤷🏻♂️
I'm not gonna lie, kapton sheet on an aluminum bed gives a really nice surface. It also doesn't seem to be seriously harmed by acetone and is cheap to replace. If I wasn't on a MK3S I'd probably still be using kapton.
It’s amazing actually. It’s an absolute nightmare to get on straight, with static and sticking together and its tendency to tear. It’s also hard to get back to a single pulled piece after it splits. But it’s magical!
Single sheets sized to your bed solve... most of those issues, but then introduce their own (it's like installing a screen protector the size of your bed). It can be hard to find appropriately-sized sheets though.
I’ve noticed that! Dealing with the roll is a pain. I’m sure there’s a dispenser that would work
5mil kapton sheets were my go-to before PEI. The extra thickness makes it indestructible. Put it down with a plastic scraper or whatever, prick bubbles with a needle, and it lasts a very very long time. Much better than 1-2mil tape in my opinion
Yeah, that’s what I like. The think PEI coated glass bed that came with this printer has been great for a lot of things but it’s not flexible like spring steel so getting things off can be difficult. It’s also not as forgiving with glue since it heats up differently. I just found with this print the tape is a good substitute.
I haven't found anything that works better than plain blue painters tape. For thin prints it's tricky to get them pried off but it works great. I miss the factory bed on my ender 3 V2 because prints would pop off by themselves as the bed cools down, but adhesion was an issue.
You are the real monster here…
Is it good for ABS and PETG ? Having some troubles with adhesion.
Abs or ASA... Nylon. But if you have bed adhesion problems with PETG which itself is like glue and won't fucking release sometimes if you pull hard... It's probably dirty bed or wrong z offset.
Probbably just weird PETG.Everything else sticks quite well but this spectrums matte PETG is just different!
For PETG I really recommend a G10 bed. It's smooth and shiny like glass, yet it sticks. It's not even originally meant for printbeds. It costs 4 usd or so on AliExpress. Worth trying. Makers Muse I think had a YT video in it. Also my clear white G10 bed looks quite cool.
But watch out, for PLA it might not be great. And idk about the high temp filaments. This is a polymer glass composite, those 100° temps might be too high.
Yes!
I currently use an old printer for ABS, and that printer does not have an PEI sheet, so Kapton (with an ABS slurry) it is.
If one want to use glass and apply Kapton tape on, here is how to do it:
- get a flat rectangular bowl or tray, 5-10 cm deep and a bit larger than the glass plate you want to cover.
- fill it with a bit of soapy water (Dish wash liquid). 1 cm height is enough.
- span the Kapton over the tray from one side to the opposite one in such a manner, that the sticky side faces down. And you must be able to slide the glass plate in.
- dip the glass in the soapy water, and then pull it up against the Kapton tape. The soapy water will prevent the Kapton to stick firmly, you can adjust the glass.
- carefully remove glass and Kapton, wipe the bubbles out and let it dry. After some hours the water is gone and the Kapton sticks on the glass.
With a bit of practicing that works like a treat.
That seems too stuck for my liking. Your bed won’t be level after yanking that hard on it.
It was perfectly level when I did the calibration
I dunno if I'm weird, but I use kapton tape under my PEI plate to fill in low areas and make the bed more level.
Lots of people use kapton as a bed shim! It works great for that!

No. This is the Snapmaker J1S
What filament is that? Good looking color
It’s Polymaker PolyLite PLA in Cosmic Meteor I believe
“you don’t even need brims”
has brims on. also just use a PEI spring steel plate
I do, for many prints. But I use lots of tools available to me.
How is this done??? I have a print I might want to try this on.
I don’t know if I should answer your question. I don’t think the grumpy old men of this sub will allow it. 😅
Imagine needing to relevel every single time
Imagine having nothing of value to offer to a conversation except assumptions and snark. 🤷🏻♂️
I am adding to the conversation. It's snark
You want to make it more magical? Put on a layer of blue painter's tape down, then lay kapton tape on that of that. It will leave a subtle imprint of the painter's tape on the 3D print that's glossy, almost like a holographic trading card
That sounds pretty cool.
Honeycomb Storage Wall pieces? I recognize those hexagon tabs
Yep! Good eye!
I use glue on the bed.
Everything sticks very well while it's hot. After finishing the bed cools down and prints pop off on their own, with a sound. No need to rip them off like OP does.
Pro tip for everyone, especially if you don’t have a super sturdy high-end printer
DONT PULL PRINTS OFF THE BUILD PLATE WHILE IT’S MOUNTED!!!
That’s how you get shitty first layers. You need to be as gentle as possible to your bed - more so if you don’t have auto bed leveling
Thank you!
Have we gone full circle and back on tape again?
