That's good to know.CT4 wrote:Elmer's Purple Glue Stick works really well with PLA on a cold bed plate.
I was originally very reluctant to try Elmer's Purple Glue Stick. The idea of coating the build plate with kids glue didn't sit well with me. One time at work I was printing on a MakerBot Replicator 2X, and the printed objects were curling on the edges and I absolutely needed the prints completed ASAP and without any edge curl. I decided to give Elmer's Purple Glue Stick a try out of pure desperation. I was surprised at how well it worked, and how easy it was to use and cleanup. I was like WHY DIDN'T I TRY THIS BEFORE! It's not at all messy or sticky like I had imagined. When applied thinly, the glue drys quickly and forms a nice smooth surface, that's not tacky whatsoever.
I like that the Elmer's Purple Glue Stick is non-toxic, and washes off easily with water, and doesn't have a strong smell.
Sometimes I just put a very small amount and spread it with a damp cloth to get a nice super thin even coat to aid adhesion a little bit.
Someone needs to make a glue stick specifically designed for 3D printers. One with a large applicator that puts the glue on in a super thin coat. Maybe make some modifications to the formula so it's easy to spread thinly and dries super fast.
