keep object stick to the glass

Hi, I have tried a few different brands of hair spray on my RepRap with mixed result, some stick to the glass better then the other. I am wondering on the commercially available 3D printer, what do they use to keep the object stick? Thanks.

The pro printers use a mesh carriage
or
Garolite
to grab bottom layers

you could try buildtak

or

PrintinZ

you could try some elmers purple glue stick
put it on with bed cold

ABS Juice for ABS prints (ABS plastic melted in 100% Acetone from hardware store)

Aqua Net Hair Spray the bright pink label for PLA.




The trick for both of them is to make sure you coat the area you want to print well, usally two coats.

The ABS juice when you have enough it will have a milk white appearance.

The PLA hairspray method you spray it till its wet once and then let it dry then spray it a second time not as much just a good coat. I usually heat it up right away after the sencond spray and by the time the print starts its dry.
