    By selecting 'Yes', you confirm you have measured your heatbed's overall dimensions. Staymag trims to fit easily, so we recommend ordering an oversized magnet to aid in installation. Lastly, you confirm that you have read the documentation in addition to our shipping and returns policies.

SKU: Staymag Category:


Staymag is our aerospace-grade, USA made, 150 ºC rated, 3M adhesive-backed magnet sheet for your 3D printer’s heatbed. Staymag offers the strongest magnetic pull strength per unit of thickness; competitors have to offer thicker magnets to achieve a similar strength. Staymag was originally developed to be continuously submerged in hot oil sumps to protect sensitive equipment from metal particulate damage.

Staymag Highlights

  • 0.85mm thin – enables faster heat-up times and reduces mass for printers with a moving heatbed compared to thicker, lower pull strength magnet sheets.
  • Uniform pull strength – covers the entire surface of your heatbed, unlike embedded magnets that can eventually come loose and create localized ‘hotspots’ of pull.
  • Designed to withstand the heat – true 150 ºC rating, unlike competitors who falsely advertise 70 ºC ‘fridge’ grade material without providing a datasheet. Staymag Datasheet here

Circular shape pricing is the same as rectangular due to scrap losses.

Consider ordering an Everflex™ plate to have the finest spring-tempered flex plate to use with your Staymag sheet.
