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.
- 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 epoxied 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
- Custom spec 3M LSE adhesive combines 468MP’s thermal properties with LSE’s incredible adhesion properties to a variety of low and high surface energy substrates.
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.
