I have used adhesion promoters for years on other printers. For borosilicate glass pei in need of conditioning, there is a trick to reconditioning those surfaces. But I am digressing.
Glue stick - 1st thing. The purple Elmer’s glue stick
- yes, you could make a thinned glue by dissolving a stick into IPA until it is thin enough to wipe
- I way I used to do it was to make a couple of wipes on the plate, then spray ipa over it and spreading it all over the plate.
Tried the Hairspray only a few times. Many have success. My tries worked but I don’t like the smell.
3rd party adhesives — Magoo, 3d gloop I hear are great.
My personal favorite is Vision Miner Nano adhesive promoter.
If the Hair spray works for you great. Others gave you a traditional tip that works.
I use Vision Miner exclusively now. As a promoter and a release agent that provides a layer between say pei and PETG.
Vision Miner Nano does only leave a very thin coating and I have not seen it transfer any wipe marks. Though like all the water soluble promoters, some times the stud sticks to the surface of the print but, it is easily washed off with water.
