PEI is a reusable and maintenance free build surface for a 3D printer, removing the need for adhesives and glues when printing ABS/PLA filaments.

All you need to do to in order to replace your existing (and perhaps weathered) PEI Sheet is remove the existing sheet from your heat bed, use a razor to remove any excess adhesive and replace it with this product! It's a good idea to ensure your PEI is clean using some isopropyl alcohol prior to printing.
