Well I decided to give the Aqua Net hair spray a try instead of slurry to keep parts attached to the bed.
My first attempts were not very successful, either with clean glass or with the etched glass so I had temporarily switched back to slurry.
This morning I decided to give it another try, and this time I used much more than I did the last time. Using more definitely seemed to do the trick. A few nice things about the hair spray.
- I can print directly on glass, no etching required
- It smells much nicer than slurry (and yes, I got the non-scented but you can still smell it)
- It's very cheap, a large can was a little over a dollar at Wal-mart
- Taking it off is very easy, just spray a bit more and wipe it off, or scrape it off if you want to
- Even with extremely thin tall parts it didn't warp or peel up, and this was with 110 c bed temp.
So for now I'm going to keep using this as an option for printing, until I have some problems, or I'm satisfied that it's working well with all different types of parts.
Once I've reached that point I'll be cutting a new bed from my piece of borosilicate glass and use that.
