ELEGOO Build Plate for Mars 3 & Mars 3 Pro

A replacement plate for the Mars 3 and Mars 3 Pro. The working face is sandblasted and anodized, and that roughness grips the first layer far better than polished aluminum — prints stay put instead of tearing loose during peel. An oversized hex socket screw holds leveling longer than the stock hardware, and an Allen key is in the box.

Specifications

• 150 × 95.6 × 10 mm plate, aluminum alloy
• Sandblasted and oxidized surface for strong bottom-layer adhesion
• Upgraded large Allen socket screw — leveling stays put through peel forces
• Drop-in replacement, Allen key included

Compatibility: ELEGOO Mars 3 and Mars 3 Pro, 143 × 89.6 mm build area. The genuine plate isn't sold on AliExpress — the link points to a multi-size flexible magnetic plate set for the Mars and Saturn lines. Pick the 143 × 89.6 mm option; the magnetic base sits on the stock plate and lets you flex prints off.
