Bed adhesive

What are the general thoughts on bed adhesive?
Dedicated bed adhesive, hairspray, Pritt stick, WHY ?

Used dimafix before, excellent .
Some decentish results using cheapo hairspray but not convinced .
Used nothing at all sometimes worked sometimes didn't

I can get 3DLAC for £10.89 or dimafix for £ 24.47 (£4.50 of that is delivery) same size.
Is the dimafix worth the extra, can I go buy an adhesive at a local (ish) shop, Edinburgh,Scotland?

Really can't see the point in not using an adhesive, cost of use is trivial compared with the cost of the filament/electricity involved in a multihour (even day) print
if it fails nine tenths of the way in due to bad bed adhesion.

I used 'Got to by Glued' for a bit trying to get PETG to adhere better. Made one heck of a mess that's hard to cleanup.

Now, I just up the bed temperature by 10 degrees and that seems to work much better.

Shall try that Bug, at the mo' pretty much everything gets a bed temp of 60 maybe up that to 65, 66 etc till 70 don't want to go much higher than that with PLA,shall try printing a Benchy or calibration cube or ... (something quick).

I like 3DLac but for me on the Bambu Lab Cool Plate it's more of a release agent than an adhesive as the plate is so stupidly sticky and shouldn't be used without glue.

For ABS on a smooth PEI a craft shop purple glue stick is excellent and just washes off.

PLA I print on textured PEI with nothing else.

Eh ? Surely a typo or some such in there .

Nope, that’s exactly how it is. The surface will get damaged if you don’t use an interface material as removing the print is a bugger.

So why would you glue it if the bed is allready super sticky. :confused:

Edit :-Oh right because your not using it as glue your using it as "release agent",

I use hairspray and it works well for me. TO be honest, I have never understood why people have an issue with prints sticking to beds during runs. I just don't have a big issue with it.

I picked up some Polymaker PolyTerra and I just can't get it to stick well at all,
it's just PLA but for some reason it resists sticking consistently which I just don't get.

Probably teaching you to suck eggs, but you tried a higher bed temperature regardless of what it's listed at?

I've had a few cheap rolls that allegedly called for 60 degree beds and wouldn't adhere at all unless I added something to make them adhere or I pushed the bed temp up to make the first could have layers stick.

yeah that's the job this weekend. I suspect it could be the bed not heating evenly?

Vision Miner Nano Adhesive. AMAZING stuff. Expensive, but worth it. https://visionminer.com/products/nano-polymer-adhesive?variant=39412520517681

I've used hair spray, layerneer bed glue and others. VMNA flat out just works.

Bed surfaces tend to wear out and stop sticking, this adhesive just keeps on working.

Turns out my bed was just WAY out of level.
