Solid support. Stable foundation. Premium prints.
Give your Ender 5 Plus the upgrade it deserves with this Platform Support Plate Kit — engineered to reinforce the build platform, eliminate flex, improve flatness and deliver more reliable large-format prints.
Key Features:
-
Reinforced support plate: A rigid metal (or aluminium) plate designed to sit under or replace the factory build platform, providing strong support across the full build area.
-
Optimised for Ender 5 Plus: Sized to match the large 350 × 350 mm (or approx ~377 × 370 mm) build surface of the Ender 5 Plus.
-
Improves print reliability: Helps reduce bed sag, uneven support and first-layer inconsistencies — particularly important for tall models, heavy infill or demanding filaments.
-
Better thermal and mechanical stability: With a stronger substrate, your hotbed and build surface perform more consistently across time and temperature cycles.
-
Easy to install: Drop-in or bolt-on upgrade that works with your existing bed, heaters and printing surface. Re-level your bed once and you're ready.
Why upgrade your platform support plate?
Large-format printers like the Ender 5 Plus benefit significantly from a strong and flat build surface. Stock platforms can show subtle flex, especially under the weight of large prints or heavy build surfaces (glass, PEI sheets, etc). This flex can lead to:
-
Uneven first layers
-
Warping or peeled corners
-
Reduced bed adhesion consistency
-
Prints shifting or failing part-way
By upgrading to a dedicated support plate, you’ll enjoy:
-
A flatter, more rigid base for your build surface
-
Fewer print failures due to platform movement
-
Better first layer adhesion and more repeatable prints
-
A stronger foundation for advanced materials and larger prints
