NO Glass Clips for Printrbot-solution by welwell Dec 28, 2012

Description

After running the extruder nozzel into my glass clip, I was determined to find a better solution. Enter SUGRU, a silicone based putty that hardens overnight, retains elasticity and resists high heat. I simply placed Sugru on the edges of the glass plate and heat bed and let it set up overnight. Now I have a surface with no obstructions. I implemented this in May 2012, and have used it with no problems since. My heat bed runs at 100 degrees C.
I have no affiliation with Sugru, but I think it's a great product.

great idea, I happen to have some sugru on order. Never used it before

Glad you like it. It's been a year now with daily prints, and the sugru is still holding strong.

Thank you for this idea!!!!!! I had trouble to hold the glass on position because (my PLA clips softened while printing. With sugru - I love this thing - it holds perfectly down and you don't have to pay attention on the extruder position any more (he could move the glass clips away from the glass)

Instructions

Sugru can be purched in the USA here: sugru.com/us/buy
Open the sugru pack and place the sugru as shown in the picture.
Let it set up for 24 hours

In addition, I bought a black Plumbing/Soldering/Torch mat at Home depot which I placed between the plywood base and the heating bed. So the layers are: plywood base, plumber's mat, Heat Bed Element, glass plate.

That's a great idea. I used Sugru to cover the solder joint on the heated bed. I happen to be a Sugru dealer as well.

Can you remove the glass? Did you put anything on the edge of the glass so the Sugru would not bond it in place?

I ask because I always remove my glass and set it on an aluminum sheet to make it cool very quickly and I have several glasses so I can continue to print with another.

Aught to work with whatever oil or maybe harder fat smeared on the edges, right?

If you (or any one else reading this)experiment with it, I and I'm sure others would appreciate a bit of feedback on the matter. Thanks guise!

No, I don't remove the glass. That's a good idea tho if you want to remove the glass. Sugru is elastic enough that it should work....

Never thought about using some form of silicone like that. Great tip! Thanks!

Think I'll buy some silicone that's usually for making somewhat temporary enginegaskets. IIRC, some folks (@instructables?)use a silicone with a vinegar/acetic acid base and mix it with (corn)starch to make a substitute; "ghetto-sugru".
