3d printing with Polylactic acid, adhesion to print bed

Click For Summary
SUMMARY

Polylactic acid (PLA) is a widely used material in 3D printing, but achieving proper adhesion to the print bed can be challenging. Users have reported mixed results with various methods, including heated glass beds, blue painter's tape, and hairspray. A recommended solution is using a thin layer of Staples blue glue stick, which has proven effective for enhancing adhesion without the drawbacks of other methods.

PREREQUISITES

Polylactic acid (PLA) is a very popular raw material used for plastic extrusion 3d printers. Myself and many others in the 3d printing community have have experienced difficulty getting the the first layer to stick to the bed.

I have tried a couple things so far
1) Heated smooth glass bed, Pros: pretty, Cons: doesn't stick
2) Glass with layer of blue printers tape, Pros: works ok, Cons: bad for small geometry like small circles or letters, ugly
3) Hairspray before print, Pros: works great, Cons: hairspray gets on other parts


Is there some material that is a more permanent solution than hairspray? Maybe some kind glue that when dry will be attractive to PLA?

Hi!

Staples (blue) Glue stick works good for me. Just a thin layer works excellent.
