Should I use 3D print bed adhesive?

The decision to use a 3D print bed adhesive ultimately depends on your specific circumstances and the type of material you are using to print.

If you are printing with materials that have a tendency to warp or peel off the print bed, such as ABS or Nylon, then using an adhesive can help improve the adhesion of your prints to the bed and reduce the likelihood of warping or lifting.

On the other hand, if you are printing with materials that typically adhere well to the bed, such as PLA, then using an adhesive may not be necessary and could even make it more difficult to remove your prints from the bed.

There are different types of 3D print bed adhesives available, such as glue stick, hairspray, or specialty products like TACK3D or PEI sheets. Each has its own advantages and disadvantages, and you may need to experiment to find which works best for your specific printer and material.
