3D Lab Tech Magnetic Sheet for build plates

Enhance your additive manufacturing setup with this high-performance 3D Lab Tech Magnetic Sheet for build plates, designed for precision applications and sustained high-temperature operation. Engineered for continuous long-term use at up to 150°C, this sheet maintains structural integrity and magnetic strength through repeated thermal cycles, ideal for high-temperature materials such as ABS, PETG, ASA, and Nylon.

Featuring a 1.5 mm thick magnetic substrate, it delivers exceptional holding force for spring steel build plates, ensuring optimal bed adhesion during active print phases while allowing clean part release post-cooling. The uniform magnetic field provides consistent contact across the entire surface, minimizing layer shifting and print warpage.

An industrial-grade 3M 468MP adhesive layer (rated for 150C long term) ensures a secure, durable bond to the printer’s build platform. This high-performance adhesive is rated for elevated temperatures and resists shear, creep, and delamination even under extended heating cycles.

Compatible with most Cartesian and CoreXY 3D printer models, this magnetic build sheet provides a reliable interface between the heater plate and removable spring steel flex plate systems, enhancing first-layer precision and long-term machine reliability.

Installation
Scuff and wash aluminum build plate thoroughly to remove any oils or residue from manufacturing, align magnetic sheet, remove backing, and apply even pressure with a roller to remove any bubbles. doing so will achieve a stable, permanent attachment within minutes.
