I'm shocked.
Just finish last printing without a glue for first layer.
Only pure glass plate and PLA filament.
Usually each time, I'm use glue or duct tape for a first layer.
Maybe this is a special PLA ?
Guys can you write me any other filament what I can use without glue ?

Did you use a heated bed? PLA does stick to clean glass if it is heated, there are people who do it that way.

PLA will stick to an unheated bed, the lower end printers are sold without a heat bed just for the purpose of printing PLA.
The bed is usually covered in blue painters tape or simple copy paper that is clipped to the glass.
I know of no other filament that will stick to an unheated bed other than PLA. I do remember some experimentation with
some nylons with an unheated bed but I do not remember the specifics of the article or where I read it at.
