Our take

A flexible PEI spring-steel plate is the single best adhesion upgrade for most FDM printers: prints stick when hot, then release with a flex when cool. WhamBam's magnetic base and quality PEI end the glue-stick and scraper era.

What we like

  • Prints release by flexing the plate
  • Excellent adhesion when hot
  • Durable textured PEI
  • No more scraping or glue

What to keep in mind

  • Must buy the right size
  • Magnetic base has a temp limit
  • PEI wears over years
Best for: Anyone fighting bed adhesion or prying prints off glass.
