Elmers Disappearing Purple School Glue Sticks, Washable, Jumbo Size, 40 Grams, 3 Count

*** Update *** For you 3D printers out there... alcohol doesnt really clean this stuff off. I tried acetone and it doesnt help much either. I happen to have some CRL 1973 Glass Cleaner on hand and it tapes off this sticky glue very well. ***************** I use this for 3D printing. It was recommended The Purple One, and yes it works great! I use this directly on a glass build plate and it STICKS! This is true, since when you miss a spot, this area has a tendency to lift and curl. My heated build plate was damaged and had to get a pane of glass to continue printing (without heat). This glue turns white and (hard) waxy when heat is applied (from the hot filament) and is very difficult to get off. It is said to use alcohol to remove it, but perhaps acetone may work better. Im sure its great for kids to do their projects, since my 7yo walks by and says, Did you buy those? Those are some HUGE glue sticks!, so I assume they use Chapstick-sized glue-sticks in school. The harder cured consistency is probably a good thing for kid projects.

These sticks are huge, much bigger in person than pictures make them appear (theres nothing in the pictures to compare by scale). Theyre about 4 inches long by 1.25 inches in diameter. I bought these specifically for 3D printer bed adhesion and they are perfect for it. Not only did they resolve the slight warping I experienced, the color changing functionality is nice, its basically purple when wet, so it goes on purple (until the layer dries) and it will turn purple again if re-wetted with water. This makes it handy to tell where youve applied it and when cleaning up, just rub a wet paper towel on it and it turns purple showing you where it needs to be removed. The bed adhesion is actually TOO good, I can tell it makes a big difference to adhesion because the prints are far more difficult to remove than they used to be. Even my preferred technique of spraying rubbing alcohol as a release agent around the perimeter of the print, no longer works with this. I suspect the glue forms such a tight bond that the alcohol cant seep under. What I find works better with this is hot water soaked towel (or paper towel), wet the perimeter so the hot water dissolves the glue at the perimeter of the print, then slide floss under and work my way through until it detaches from bed. After removing the print I find the glue has done nothing to damage the print itself. It washes off the print and the bed completely with water alone (I clean the bed with rubbing alcohol as well).

I love the purple glue. You can see if you have the whole area covered. Great for all types of paper.

Elmers Glue Stick Disappearing Purple always works well and purple color fun to use.

Used by disabled kids in my classroom

Always depend on Elmers Glue sticks to be of superior quality and was not disappointed.

The purple color makes it easier to see coverage on the print bed. Cleans up easily with water.

I use this to flatten my eyebrows when applying halloween makeup. I have sensitive skin and this worked well and didnt irritate my skin. Perfect.

Very neat and clean, non-greasy at the same time sticks well. My sons school will not accept anything besides this, its that good.

I bought a few packs since I print a lot and wanted to give it a try and it works like a charm. Easy to clean up and lasts a while a few hundred 3d prints if you know how to use it
