Why use a Glue Stick for 3D Printing?

A glue stick helps your 3D print stick better to the print bed. A print bed is the surface where your object is printed on. Basically, the plate.

Sometimes your 3D print can come loose or warp a bit during 3D printing. Especially with larger objects with PLA it could make a big difference. If your first layer isn't sticking well, or your print comes loose during 3D printing, it could be worth trying to 3D print with a glue stick. It's usually recommended when you have a glass bed or PEI bed. Though in our experience, PEI actually sticks pretty well on its own.

How do you apply it?

Make sure the bed is clean and cooled down. Apply a thin layer with the glue stick over the print surface, and let it dry briefly before starting your 3D print. When you're done printing and the bed has cooled down, you could remove your 3D print. The glue should let go on its own.

How do you clean the bed?

A little warm water and a cloth is enough, glue stick dissolves easily in water.

Which glue stick?

Pretty much any glue stick works, and you don't need a special 3D printing glue. Though official 3D printing glue does make cleaning your bed a bit easier.
