This is the most commonly used Build Plate coating, especially when you are printing with PLA filament. PLA sticks to it very well, and you can usually print 5-10 items before having to replace it. We use 3M Blue Tape on all our build plates because we find it works best, and is easy to replace. While some manufacturers sell large sheets of it for $1 each, we buy it on a 6” wide x 60 yard roll from McMaster Carr for about $60, which makes our cost about $0.27 per linear foot. Even if your build plate requires two lengths joined together, that cost is about half of what most others charge.
