What customers say
Consumers consistently praise this build plate for dramatically improving the 3D printing experience, highlighting two major themes: ease of use and reliable quality. Users report exceptional bed adhesion during printing, eliminating frustrating failures. Once cooled, the spring steel design allows prints to release effortlessly with a simple flex, making post processing much faster. This reliable performance and the plate's durable construction establish it as a high value upgrade that delivers consistent results across various filament types.
Know before you buy
This plate is specifically engineered for the WonderMaker ZR with precise dimensions of 310x310mm and integrated positioning holes. While it may physically fit other 310x310mm printers, the alignment holes and magnetic base compatibility are optimized exclusively for the WonderMaker ZR.
No, the textured PEI surface is designed to provide excellent adhesion for most standard filaments without the need for additional adhesives. Simply ensure the surface is clean and free of oils or dust before you start your print.
Once the print is finished and the plate has cooled, simply remove the sheet from the magnetic base and gently flex it. The print will typically pop off the textured surface with minimal effort.
The textured PEI surface is highly versatile and works exceptionally well with PLA, ABS, PETG, TPU, and Nylon. The texture helps minimize warping and provides a reliable grip for these common materials.
For routine maintenance, wipe the surface with high-percentage isopropyl alcohol (IPA) using a lint-free cloth to remove oils and residue. Avoid using harsh chemicals or abrasive tools that could damage the PEI coating over time.
