K2 Plus Smooth Build Plate 370x370mm - Double Sided Flexible Print Bed

In this review of the K2 Plus Smooth Build Plate, the bottom line is simple: this 370x370mm double sided flexible plate is aimed at K2 Plus owners and hobbyists who want a durable, textured alternative to glass. The reviewer found the main reason to buy is the combination of a 0.4mm ultra-high temperature stainless steel core and dual textured films that offer predictable adhesion and easy part removal, particularly for PLA and PETG prints. This plate is judged as a practical upgrade for those seeking better surface finish and long term flatness.

Key Features

• Ultra-high temperature stainless steel: the 0.4mm steel core resists bending and rust, keeping the plate flat under repeated heat cycles for reliable first layers.
• Double-sided textured films: one PEO side shows a large diamond pattern and the PET side a carbon-fiber style pattern, giving neat, repeatable surface finishes without color conversion.
• Improved elasticity: the chosen materials make it easier to flex parts off the bed, reducing the risk of damage when removing finished prints.
• Stable adhesion: tested on multiple machines, the plate provides good hold for common filaments like PLA and PETG while still allowing part removal when cooled.
• 370x370mm fit for K2 Plus: the size is matched to the K2 Plus platform so installation is straightforward for owners of that model.

Who It's For

This plate is best for Creality K2 Plus owners and small shop users who print mostly PLA and PETG and value a textured surface that improves visual finish without extensive bed prep. Makers who prefer a durable metal core over glass will appreciate the flatness and reduced risk of film delamination at higher temperatures.

It is less suited to users who need absolute maximum adhesion for exotic materials without any additional tweaks, or those who rely on adhesive glues or rafts as a primary bed strategy; some customers reported mixed adhesion results depending on filament condition and print speed, so advanced tuning may be required for very intricate or high-speed prints.

Pros & Cons

Pros

• Durable stainless steel core that resists warping and maintains flatness after repeated use.
• Two different textured surfaces for aesthetic and functional choice without swapping plates.
• Good elasticity aids part removal, reducing the need for prying tools.

Cons

• Adhesion is mixed for some users; humid filament or high-speed settings may require tuning or higher bed temperature.

Our Verdict

The K2 Plus Smooth Build Plate is a sensible upgrade for K2 Plus owners who want a robust, flat platform with two attractive textured surfaces and easier part removal. It delivers strong value for routine PLA and PETG printing, though users should expect to tune bed temperature and speed for the best adhesion with difficult filaments.

Frequently Asked Questions

Will this plate fit the K2 Plus out of the box?
Yes, the plate is 370x370mm specifically sized for the K2 Plus and should fit without modification.

Which side should I use for PLA?
Both sides work with PLA; the PET side gives a carbon-fiber style finish while the PEO side provides a larger diamond texture-choose by aesthetic preference and test adhesion.

How do I maintain adhesion?
Keep the surface clean with alcohol, monitor nozzle-to-surface distance, and increase bed temperature or slow print speed for humid filaments or intricate models.
