Glue for the bed surface?
-
Hi *,
What do you guys use to glue the surface of the bed to the aluminum plate?
I understand that the most commercial suppliers use that M3 4xx "tape" which is stable at higher temperatures. I had a lot of problem to apply it manually to surfaces. I tried a glue in spray cans which should be stable till 150° but it lost it's bond at 60°C already.
I search for a glue which is more like a lotion which can be easily applied and which can displace every air below the surface.
Any ideas?
Cheers, Chriss

what problems did you have?

@Veti
Well, the usual problem you have if you apply a sticky foil to a surface. I have air bobbles, the glue on the film changes it thickness if it came in contact with the surface and you have to pull it off for "reorganization". Is is freaking expensive, bad to store and not very available.I'm not a fan of glues which are like a film, I prefer liquid glues....

Most people I think use flexible build plates now with PEI surfaces
-
sure.. buth they do not stick on the aluminum plate just by the pure air. All of them needs to be glued somehow....
-
@Chriss you get a magnetic sheet with them. That attaches to the aluminium plate as they have a sticky back and then that holds the flexible sheet in place.
I have them installed on all 3 of my printers and my resin printer -
OK, jay... I think yo do not want to understand me..... So I will try it again:
And how do you think that the lower magnetic part sticks to the aluminum plate? By it's good will?
It makes no difference what the upper site of your build plate is... there are enough religious fights going on. The question is HOW to glue the (whatever) material to the aluminum thingy. -

@jay_s_uk
And this back sucks....I search for a replacement of exactly this pile of shit. -
@Chriss Not on any of mine it isn't.
Its typically 3M tape and I've taken them up to ~120 degrees C with no sign of failure -
They do not fail at temperature. They overall concept is broken. You can not avoid air bobbles and you can not change the orientation while you apply it.

just use the same principle as with applying a screen protector on your phone.
slowly and use a soft scraper to push out air bubbles

That may work with small foils... don't know, I glue huge foils always wait. Just some drops of screen cleaner in some water.

Did this ever worked for you? I do not see any posibillity to push a air bobble out of the middle of a 500x500 bed. The M3 tape is far to sticky in my opinion.
-
I installed my 500x500 build surface with no bubbles at all.
If you have some, just use a needle to pop them and let the air out. Problem solved -
Installed a Lot of 300x300 pei sheets. If you are going slow its bubblefree

thats not gonna solve the problem of applying the next layer without bubbles
if you can't get the hang of installing the film bubble free maybe buy a heated bed with pre-installed magnets and steel sheets with pre-installed PEI or whatnot.

Hi,
I tried BuildTak's system on one of my printers and like it so much that I put it on my other printer.
A little patience and care is needed to be sure.
I fold back an inch or so of the protective backing to expose the sticky bit and get things lined up just right.
Then using a small wooden block I apply pressure over that area.
Then I gradually pull back the protective backing applying pressure as I go.

We use Rapid Tac. It allows us to reposition and work out any bubbles before drying.. It’s main purpose is for the vinyl sign making business.
edit we don’t use this as the glue- we use it to apply the 3M backed PEI sheets to build surfaces, etc..
