Print Bed Magnetic Sheet

Adhesive-backed magnetic base sheet for a 180 mm 3D printer bed. This is the magnet layer that bonds to the aluminum bed and holds a removable spring-steel build plate in place.

Why use this sheet

• 180 mm x 180 mm size for small-format beds, including Micron-class and other Printers for Ants builds using a 180 mm bed stack.
• High-temperature magnetic base for heated-bed use; the current supplier spec rates the magnet for use up to 140 °C.
• 3M 300LSE adhesive backing for bonding the magnet to a flat aluminum bed plate.
• Trim-to-fit magnetic sheet format for custom bed stacks and replacements.

Specifications

• Size: 180 mm x 180 mm
• Adhesive: 3M 300LSE high-strength acrylic adhesive backing
• Use: magnetic base layer for removable spring-steel/flex build plates
• Bed temperature note: supplier spec lists the magnet as good up to 140 °C

Fitment

Use this with a flat 180 mm aluminum bed, including the 180 mm variant of our Black Anodized Ultra-Flat Aluminum Bed. It is intended for small Voron/Micron-style and Printers for Ants bed stacks where a removable spring-steel plate is used.

Gotchas

• This is the magnetic base only; it is not a PEI sheet, spring-steel sheet, heater, thermistor, or aluminum bed.
• Install on a clean, flat, degreased bed surface and give the pressure-sensitive adhesive time to wet out/cure before heating hard.
• Check your actual build plate size before ordering; this listing is for 180 mm x 180 mm.
