3d printing with Polylactic acid, adhesion to print bed

  1. Nov 6, 2013 #1
    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?

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