Glue goes even further... · 5:33am Apr 6th, 2019
There is only one format appropriate for relaying to you the story of the glue that came on the back of a glass print bed I got for my 3d printer.
>Be...
>me.
>Old printer dies hardcore. Get new one.
>it arrives. Quickly assemble it as much as possible.
>Some parts need to be printed by the printer before upgraded parts can be used.
>However, glass bed can be applied, and should be, for reasons of printing properly.
>notice glass bed has glue backing.
>Not good.
>bed has to be removable for cleaning, and I cant leave the paper backing on there. It will catch fire, probably.
> attempt to remove glue with some rather potent cleaners.
>glue remains on the back.
WTF.bbq
>touch glue to see if the tackiness is gone.
>Entire glass bed is suspended from my finger as I pull my hand away form the bed!
>loose layer of skin removing finger from glue.
>Soak for 20 minutes with cleaner.
>Glue doesn't budge!

>Notice odd thing about the edge of the plate. Apparent chipping. Inspect.
>Not chipping.
> "Glue" is actually a 2mm thick layer of polymer filled with an adhesive!
>looks up the glass bed's specs.
>Sees "Thermal Adhesive layer bonds to bed when bed is heated."

>Gets to peeling layer off slowly.
>Takes a lot of scraping and chemicals to do anything at all to this junk.
>Realizes that 95% of thermal adhesive's sticking power comes after it's been heat-activated, and this stuff heat activates at 60C.
>No way it got to 140F in transport.
>This glue is literally using only 5% of its power!
>Imagines glue activating like:
>get pealed off glue patch.
>use it to stick together two pieces of scrap aluminum.
>Toss in oven at 140 for a few min.
>remove from oven.
>get pliers.
>attempt to separate scrap bits.
>Pull till I feel my shoulders start to give out.
>scraps are note even a mm more separate form another than they were before!
>attempt to jump on one scrap while other scrap is clamped.
>Scraps support my bodyweight, even with the jump!
>Get old blacksmith's hammer I keep for breaking things apart on occasion.
>5 pounds of steel, pointed wedge head.
>Give one scrap bit what for!

>Scrap doesn't even notice it's been hit...

>Aluminum plate fucking dented and bent!
>glue is fine.
>parts might as well be welded together.
>HOLY. FUCKING. SHIT!
>Decide to see if I can buy this SSJ3 Glue.
nope.sadness
>Realize if I hadn't peeled this off that bed would literally never come off the carriage.
>Would have had to throw out the heated bed and get a new one.
>All hail random thermal adhesive, lord of the glues!
This is a very random story about glue and printers.
Meep found the Sovereign Glue. Of course you can't get it to release, Meeps. That stuff only lets go with Universal Solvent (or a Wish or Miracle spell)...

Nice.
Jesus fuck that’s some strong glue.
5039055 It's a non-epoxide polymer (ie not an epoxie) which uses nanotechnology as the adhesive. Not nanomachines, but like, this stuff is the result of studying super tiny scale stuff back in like 2011. It's basically a nanoglue, and is sadly not sold outside of industrial applications yet :c
ALso this bed was 25.99.
The glue is apparently 2/3rds the manufacturing cost!

So clearly this adhesive is in fact available for sale (for about $26 or so), you just need to remove some sort of pesky glass print bed from it first before you can actually do anything with it.
But if its a thermoplastic glue on a heated bed, firstly, what was it supposed to stick the thing to while its cold, and second, it wouldnt no longer be stuck to that thing so good when it was actually working as a heated bed?
Did someone just send you a tablet screen with thermal bonding instead?
Considering how much work that was, are you certain you were supposed to remove it?
5039062
Yeah, my little sister is a materials scientist who specializes in nanomaterials. There is some really really neat engineering coming out of that research.
5039084 Suposed to, no. Wanted to/needed to for my use case? Yes.
5039070 Fair enough!
5039087 Given your family, I'm not surprised. Please let me know if you have an eccentric roboticist cousin with a suspiciously hot SO who is very socially awkward.
Goddammit Meeps, my sides!!

Was that a reference to something? That seems like a reference to something.
Weird Science?
5039097
Hmmm. . . I have lots of cousins, but none that matches that description. . .
5040137 OH! It's a reference alright... but I'll never tell! *promptly falls through the floor*
If you were not supposed to remove it, then what was your use-case where you needed to remove it?
Also, how much are you selling your leftover super-duper-uper-glue for?

I did not want the print bed permanently affixed to the carriage so i can utilize other print beds. Glass is a very good 3d printing surface, but like all materials it has its advantages and disadvantages. For example, when utilizing the stock bed, it is very easy to remove parts. Less so when using glass.
More importantly, eventually the glass needs to be removed so left over layers of PLA can be cleaned off it. You cant' exactly soak a whole 3d printer in a tub of water, dish soap, and simple green and expect it to work again. You also DO need to clean the bed as a 1 micron thick layer of plastic isnt' realy going to be visible, nor scrape off the bed easily, and that WILL cause problems printing because suddenly the bed is uneven as 4-5 of these layers have piled up and your nozzle drags and scrapes on one section of the print...
I have no leftovers. I used it to fix bits of my truck.
