Compare the BuildTak-style Smooth PEI Ultra Sheet with 3 other pei build sheets
Our verdict
Mirror-smooth bottoms for display parts. Smooth PEI still wins when you care about glossy first layers. Adhesion is strong (sometimes too strong on PETG), so we keep a glue-stick or release agent nearby for sticky filaments. Overall 8.4/10.
